The Helix Moonlight is a softer hybrid mattress that doesn’t compromise support or durability. It’s a great choice if you are longing for that memory-foam feel, without feeling like your spine’s alignment is sinking out of place.
Our in-house testers, along with Dr. Tedesco, our chief medical product tester, tried out the Helix Moonlight in our studio to determine whether it’s worth its price and who it best fits. The Helix Moonlight is great for couples, combination sleepers, and hot sleepers in particular, due to its highly versatile hybrid design.
I’ve been reviewing mattresses with Sleepopolis for a few years now, and I appreciate the value of a good night’s sleep as an athlete and certified wellness coach. Our team at Sleepopolis has reviewed over 500 mattresses, and since 2024 alone, we’ve helped 15,622 people find the right bed for their home. Our team of expert testers, combined with the medical guidance of our chief medical advisor, Dr. Raj Dasgupta, MD, FACP, FCCP, FAASM, and the hands-on insights of our chief medical product tester, Dr. Joseph Tedesco, has offered unbiased reviews using our testing methodology that have helped at least 60,100 people get a mattress that fits their unique sleeping needs.
In this review, I’ll go through everything you need to know about the Helix Moonlight mattress, so you can decide if it’s the right bed for your sleep and lifestyle needs.
Our Helix Moonlight Mattress Review Summarized
The Helix Moonlight is a more affordable hybrid mattress that is highly durable despite its softer-than-average 6 out of 10 firmness. The mattress is a great choice for hot sleepers, especially when you add Helix’s GlacioTex Cooling Cover. The budget-friendly Helix Moonlight punched above its weight in many of our performance tests, showing that a comfortable, quality mattress doesn’t have to break the bank.
The Helix Moonlight mattress is a hybrid bed with a medium feel, providing both softness and support for back and stomach sleepers. It excelled in our cooling and motion isolation tests, making it a fine pick for couples who sleep hot. It’s likely a touch too soft for certain sleepers, like those over 230 pounds, especially if they sleep on their side.
What our tester says:
“I feel great on my side. It’s a bit softer than average, but still supportive enough for my spine to feel neutral. I feel pretty weightless overall, and super comfortable to boot.”
Our Review Process
At Sleepopolis, our team of certified sleep science coaches personally test each mattress. We start by unboxing the mattress to figure out how difficult (or easy) it is to get the mattress from the box to the bed. Then, we spend time lying on the bed in different positions, taking time to assess it on our back, stomach, and side. Next, we perform our Sleepopolis tests, using specialized tools to measure qualities like motion transfer, bounce, and pressure relief. Our last step is to open up the mattress and take a look at each layer. These steps allow us to give our final verdict on each mattress.
Helix Moonlight Mattress Sleepopolis Scores
Our Scoring System
We rate each mattress on a scale from 1 to 5 to reflect its overall quality. The number is comprised of individual scores from hands-on testing of materials, firmness, pressure relief, motion transfer, cooling, responsiveness, and more. Learn more about our methodology.
Helix Moonlight Mattress Overview
The Helix Moonlight is an affordable ($999 for a queen) hybrid mattress that combines coils and foam. The mattress is designed to offer a softer feel while still providing sturdy spine and joint support.
Our testers found the Helix Moonlight a great choice for couples, due to its top-notch motion isolation (4.3 out of 5), edge support (4 out of 5), and responsiveness (4 out of 5). In addition to couples, these performance scores indicate that the Helix Moonlight would be a great pick for combination sleepers, thanks to its versatile hybrid design and responsive support across different sleep positions.
In the testing studio, we also found that the Helix Moonlight had solid temperature regulation (4 out of 5 for cooling). We tested this mattress without the optional GlacioTex Cooling Cover and found it to be “cool-to-the-touch, making it a good pick for hot sleepers. However, those who really heat up at night will likely want to pay the additional $281 to stay cool and comfortable throughout the night.
Experiences may vary by person. But heavier sleepers, especially those who sleep up on a bed’s edges or share the bed, may find Helix Moonlight’s edges sag a bit too much for their comfort. Heavier sleepers want a mattress with edges that can better support their weight. Additionally, our heavyweight tester didn’t feel excellent pressure relief, but our pressure map didn’t show much buildup, suggesting that some larger-bodied sleepers may find their sweet spot on the Moonlight.
After reviewing all the test results and conducting my own research, I’d suggest the Helix Moonlight for couples looking for the most bang for their buck in a soft yet supportive mattress.
Who I Recommend the Helix Moonlight For
- Lightweight and average-weight back and stomach sleepers who want sturdy support but prefer a softer feel will appreciate the Moonlight’s healthy balance of both.
- Couples and restless sleepers will appreciate the Helix Moonlight’s ability to isolate disruptive motion transference.
- Hot sleepers should find the Helix Moonlight dissipates their body heat well, thanks to its layer of coils that stimulate airflow throughout the bed and its breathable knitted Tencel cover.
Who I Don’t Recommend the Helix Moonlight For
- The Helix Moonlight had decent edge support, but sank a bit more than average when testing it with heavier weights. Heavier couples may prefer a mattress designed for heavier sleepers, such as the Helix Plus.
- Fans of firmer beds will likely find the Helix Moonlight too plush for their liking despite its hybrid design.
- Heavier side sleepers may not experience enough pressure relief for their joints and back with the Helix Moonlight.

Helix Moonlight Value
I compare a bed’s price to its construction quality, fine print, and performance in our testing. The Helix Moonlight’s queen-size model is currently available for $999, which is a decent price considering its quality and when compared to similar-grade hybrid mattresses.
The brand Helix is also well-known for using more eco-friendly foams and offering a lifetime warranty, reflecting its confidence in its products. Looking at all its features, its 4.3 out of 5 overall performance score, and comparing the price to other hybrids, I would say the Helix Moonlight is worth its price.
If the Helix Moonlight is still out of your price range, you can check out some of our top choices for a cheap mattress.
What Is the Helix Moonlight Mattress Made Of?
Dr. Raj Dasgupta offers some insight on the benefits of hybrid mattresses, saying, “A hybrid mattress is a special kind of mattress that combines the support of traditional springs with the comfort of modern foam. It aims to offer a balance between firmness and softness, making it suitable for various sleep preferences. It’s like a superhero of sleep comfort, providing the best of both worlds for a better night’s rest.”
The Helix Moonlight is a softer-than-average hybrid, measuring 11.5 inches tall. It features multiple strategic layers, including a breathable knitted Tencel cover, three comfort-foam layers, a coiled layer, and a high-density poly foam foundation. Helix offers its GlacioTex Cooling Cover for an additional $281. Although sleepers who don’t get too hot at night should enjoy a breezy night of rest with the included cover, based on our tests, super-hot sleepers will likely think the optional cooling cover is well worth it.
Cover – The Helix Moonlight’s top layer features a breathable knitted tencel cover that provides a sturdy surface while remaining soft. You can also add the GlacioTex Cooling Cover, which is cool-to-the-touch and a great mattress topper for an additional fee.
Comfort Layers – The Helix Moonlight features a gel memory foam layer beneath the sleeping surface, designed for comfort. Underneath this are two additional layers of latex-based responsive foam for enhanced cushioning.
Transition Layer – For support and airflow, there is a layer of 1000 individually wrapped steel coils, reinforced lengthwise for enhanced edge support.
Base Layer – At the bed’s foundation is a thick layer of high-density foam to offer structural stability to the entire bed.
Helix Moonlight Mattress Firmness
I find it always important to remind readers that firmness, something I also refer to as a bed’s “feel”, is subjective. Dr. Raj Dasgupta said, “Some people may prefer a hard mattress that they won’t sink into, while others might be more comfortable on a soft mattress that’s more plush.” This is because a sleeper’s preferred, or healthiest, bed firmness is best determined by factors such as sleep patterns and body size.
For example, side sleepers tend to prefer a softer firmness that cradles and cushions their joints without causing inflammation. Whereas heavier sleepers will likely appreciate a firmer feel, which can prevent them from sinking into a bed’s comfort layers and compromising their spinal alignment during the night (leading to inflammation).
Using our firmness rating guide, where 1 is the softest and 10 is as hard as it gets, our in-house testers found the Helix Moonlight’s firmness to be a 6 out of 10. This is just a bit softer than the industry average or most common firmness level for beds, at 6.5 out of 10 (medium-firm feel). Helix refers to the Moonlight as a hybrid with a “soft feel” that still offers healthy support for all sleeper types. But our in-house tester tried it in all sleeping positions and reported their results.
On their side, our in-house tester found great joint and shoulder cushioning, without concerns for a lack of support that could lead to increased back pain. They were quite pleased on their side overall, saying, “On my side, I feel adequate pressure relief and support. There’s a great balance between the two that creates an almost weightless sensation.”
When they rolled onto their back, they felt a safe, soft feel that didn’t compromise support. They found that their spine was neutral and aligned, while remaining super-cushioned and comfortable. They said, “I feel super weightless on my back. It feels like I’m crowd surfing, and a bunch of foam hands are lifting me up. I would definitely recommend this to back sleepers.”
Finally, on their stomach, the in-house product expert was actually surprised by the level of support they felt, despite the soft feel. Explaining, “I thought it would be a bit too soft, but the foams are very responsive, so they push back against my hips and prevent them from sinking in too far.”
As I said, experiences can vary depending on one’s size and weight, but these are pretty impressive findings from our tester. It validates Helix’s Moonlight claims that the bed is a softer option for back and stomach sleepers.
Helix Moonlight Mattress Performance
Our team of sleep specialists and expert testers carefully reviews every mattress we test at Sleepopolis to deliver unbiased, research-based reports for every bed we review. Our testing is designed to help sleepers determine whether a mattress is right for them based on their unique sleep needs. I’ll break down the performance results we found with the Helix Moonlight, including its cooling and pressure-relieving abilities, and more, below.
Helix Moonlight Mattress Pressure Relief Performance
According to our chief medical advisor, Dr. Raj Dasgupta, “Your mattress can make your neck pain worse if it isn’t supportive, isn’t the right firmness, or can’t relieve pressure points.” Mattresses that lack pressure relief can make existing back pain worse and leave you aching rather than refreshed. That is why we do multiple tests to assess how well a mattress can help alleviate pressure buildup and prevent inflammation in your joints or shoulders.
The Helix Moonlight demonstrated average pressure relief, earning a 3.9 out of 5 in this category. To determine this score, we conducted two tests by multiple testers of varying sizes and sleep preferences.
Each tester tried the Helix Moonlight in different sleeping positions and described the pressure relief they experienced, providing us with a first-hand, subjective assessment. While they are resting on the bed, we also use a pressure map that measures pressure buildup in pounds per square inch (PSI), allowing us to make objective determinations about the bed’s pressure relief.
For context, a PSI of around 14.58 is considered average for side sleepers, and a PSI of 12.43 is typical for back sleepers. Lower PSI scores than the average indicate better pressure relief, and higher scores indicate worse pressure relief.
The Moonlight does a nice job of relieving pressure at the back when sleeping on my side and back. However, as I mentioned earlier, this is a soft mattress, so back pain is likely to occur when stomach sleeping. The mattress was also able to cushion the shoulders when side and back sleeping, which is perfect for relieving stiffness and aches in this area. Similarly, the Moonlight cradles the hips really well when side and back sleeping, so these sleepers should find hip pain relief.
Overall, the Helix Moonlight mattress performed excellent in relieving pain in the back, hips, and shoulders for side and back sleepers, but I wouldn’t recommend this mattress to stomach sleepers looking for pain relief in these areas. Instead, I’d steer them to our best mattress for stomach sleepers roundup for more supportive and firm options.
Lightweight Sleepers (under 130 pounds)
Our in-house lightweight tester felt excellent pressure relief resting on their side, giving the Moonlight a 4.5 out of 5 for the experience, and saying, “I feel great on my side. It’s a bit softer than average, but still supportive enough for my spine to feel neutral. I feel pretty weightless overall, and super comfortable to boot.” Their impressive 9.94 PSI reading also fully backed their claims.
On their back, they gave the experience a 5 out of 5, and the PSI reading was excellent at 7.76. Their perfect score wasn’t a surprise based on their description, “My back feels fantastic in this position. I’m getting cushioning along my entire body. This bed is a great choice for back sleepers who want pressure relief without sacrificing support.”
Average-Weight Sleepers (130 to 230 pounds)
Our average-weight tester, Livvi DiCicco, wasn’t super impressed resting on her side, giving the experience a 3.5 out of 5. She explained her score, saying, “My hips are sinking in way lower than my shoulder. I just don’t like it on my side, because I am not getting enough sinkage around my shoulders.” On her back, she felt a similar lack of pressure relief, saying, “Same thing, but to a lesser degree on my back. My lower half is sinking in more. I feel like it might cause tension the longer I lie down here.” She also gave the back sleeping experience a 3.5 out of 5.
Notably, our pressure map showed impressive results, suggesting that other average-weight sleepers may have a different experience. Livvi’s side-sleeping PSI score was 11.04, and her back-sleeping PSI score was 7.94.
Heavyweight Sleepers (over 230 pounds)
Caine Wilkes found himself sinking too much into the bed’s cushioning when resting on his side, giving the experience a 3 out of 5. He explained, “I feel a lot of cushioning on this bed, but there might be a little too much of it. My hips are sinking in much lower than the rest of my body, and I feel like that’s what’s causing pressure buildup.” Moreover, we did read some pressure buildup on the map at 15.36.
When Caine moved to his back, he felt a little better, giving a slightly higher 3.5 out of 5 score. Caine reported, “It feels better on my back, but I’m having the same problem. I’m sinking into the mattress unevenly, and I am just not getting the support that I’d want.” Despite how he felt, the pressure map read a 10.73 PSI, which is quite good considering Caine’s weight. And suggested that the Moonlight may accommodate some heavier back sleepers.
Our chief medical product tester, Dr. Tedesco, stopped by our testing studio to provide his expert input. From trying the Helix Moonlight on his side, he suggested that side-sleepers should “fall asleep relatively quickly, but may have to move a bit because they don’t feel very supported,” and gave the side-sleeping experience a 4 out of 5.
When he switched to his back, he explained his grading, saying the Moonlight had a “low 4 out of 5 for back sleepers, but a strong 4 out of 5 for stenosis patients because it provides the leg lift and a posterior tilt feeling.”
Dr. Tedesco also said he didn’t feel the Moonlight was great for stomach sleepers, because “It’s too soft. It puts you in extension because of the softness.” However, he did appreciate the Moonlight’s reliable hybrid design, saying, “Someone who doesn’t want a foam mattress will be able to sink into the Helix Moonlight but still get some pushback from the coils.”
Helix Moonlight Motion Isolation
If you’re a restless sleeper or share the bed with one (or both apply), motion isolation is going to be important to you. Dr. Raj Dasgupta says, “A mattress with good motion isolation offers undisturbed sleep, comfort for couples, personalized support, pressure relief, versatility, a quiet sleep environment, longevity, and minimized partner disturbance.”
If you ever share a bed with someone who moves around at night, and feel every one of their moves, or hear your bed’s springs creaking and crackling, this means you’re likely using a bed with bad motion isolation. After multiple tests, we gave the Helix Moonlight a 4.3 out of 5 for motion isolation, which is better than average. To get this score, we conducted two tests: a partner test and a ripple test.
In the partner test, two of our in-house testers simulated sharing a bed. It’s a pretty straightforward test, where one person rests on the bed, and another person gets in and out of the bed or changes sleeping positions next to them (and vice versa). The resting tester notes and grades how much they feel the other tester’s movements.
For the Helix Moonlight, our in-house testers gave the partner test a grade of 4 out of 5. One of the testers explained their final score, saying, “During the partner test, I could tell that someone was getting into bed and moving around beside me, but I think the pillow top did a good job muffling most of her movements. Because I never felt like I was on a rollercoaster or super disturbed.”
Then, for the ripple test, we place a large clear container of water on one side of the bed and observe how much it ripples or splashes out in response to someone getting in and out of the bed or changing sleeping positions next to it. The testers noted that despite feeling a lot of bounce, the water stayed “pretty calm and still the whole time.” They gave the score a perfect 5 for 5.
I would definitely suggest the Helix Moonlight for couples sharing a bed based on these results. If you wake up every time your partner moves or comes back from the bathroom, this bed could be the solution.
However, if you still don’t think the Moonlight is the right choice, but are concerned about motion isolation, consider checking out one of our top picks for couples sharing the bed.
Helix Moonlight Responsiveness
We observe how well a bed returns to its original shape after someone moves on its surface or weight is applied. Then use this observation to grade the quality of a bed’s responsiveness. If you’re a combination sleeper, for example, you’ll want good responsiveness to ensure the bed follows your movements with reliable support, without allowing your joints or spine to sink too much, which could cause misalignment or pressure buildup.
In addition to combination sleepers, couples will also appreciate responsiveness. Because it is a sign that a bed will likely offer a good surface for moving around on or for sex.
Our in-house testers found the Helix Moonlight to be very responsive, giving it a 4 out of 5 overall score for the category. To get this score, we used three tests: a switch test, a weighted kettlebell test, and a bounce test.
Switch test: In this test, a tester simply rests on the bed, switching sleeping positions and assessing how easy it is to do so, while consistently feeling the bed’s bounce-back support as they move. The tester wrote, “The three layers of foam have a quick response to pressure, which made it pretty easy to move around on this bed. I think most people will be able to move around on this bed with no problem.” The tester gave the switch test a 4 out of 5.
Kettlebell test: We place a 53-pound kettlebell on the bed and measure how deeply it sinks into its layers. When we placed the kettlebell on the Helix Moonlight, we measured 3.8 inches of sinkage, which is slightly above the average of 3.7 inches. It’s a decent, but not excellent result, with our testers giving the test a 3 out of 5 accordingly.
Bounce test: Here, our testers climb a six-foot ladder, drop a 25-pound ball onto the Helix Moonlight, and measure how high it bounces back to assess the bed’s bounce. The testers recorded a bounce-back height of 30 inches, which is excellent, considering the average recorded ball bounce is 16.3 inches. Our testers gave this test a 5 out of 5.
Based on these findings, couples and lightweight or average-weight combination sleepers should find the Helix Moonlight great. However, considering the sinkage, heavier sleepers may find the responsiveness lacking and prefer a mattress more suited to their weight.
Helix Moonlight Cooling
If you find yourself settling into bed and then rushing to adjust the AC because you feel trapped in your own body heat, you likely have a bed with subpar cooling or are what we’d call a “hot sleeper.”
The Helix Moonlight is a hybrid mattress that should appeal to those who wake covered in sweat. As Dr. Dasgupta said, “Hybrids offer more support and airflow because the coil system in a hybrid mattress promotes air circulation, leading to a cooler sleeping experience, which is especially beneficial for hot sleepers.”
The Helix Moonlight offers multiple cooling features, including its breathable knit Tencel cover and a layer of coils that generate airflow throughout the bed’s core. Additionally, Helix offers, for a fee ($281), its GlacioTex Cooling Pillow Top, for even more enhanced cooling. But we conducted two tests to see how well these cooling features really perform and gave the Helix Moonlight with its standard cover a 4 out of 5 rating based on the results.
Feel test: In this subjective test, a tester lies on the bed and assesses how comfortable the bed’s temperature regulation is. They described their experience, saying, “As I lay there, I didn’t really feel the bed heating up at all. I thought the cover did a great job keeping me chilled and preventing my body temperature from rising. If anything, I felt more cool than neutral.” They gave this test a 4 out of 5.
Thermal gun test: In this objective test, we use a thermal gun to measure a bed’s core temperature, before and after one of our testers rests on the Helix Moonlight for roughly five minutes. For reference, if the thermal gun reads a temperature increase of less than 5 degrees, it’s considered top-notch. An increase of 5 to 10 degrees is considered good, 10 to 15 degrees decent, and anything more than 15 degrees would be deemed poor.
The Helix Moonlight’s beginning temperature read 64.1 degrees. After our tester rested on it, we pointed the thermal gun at the mattress and measured 70.8 degrees, a 6.7-degree increase over the baseline. This is at the better end of good cooling, and just below excellent. And our tester gave the mattress a 4 out of 5 for this test.
The tests suggest hot sleepers will likely find comfort with the Helix Moonlight. But I would suggest that super-hot sleepers opt for the GlacioTex Cooling Cover, just in case the Moonlight on its own isn’t enough. If you’re a hot sleeper and still not feeling the Helix Moonlight, check out our top picks for the best cooling mattresses available today.
Helix Moonlight Edge Support
People underestimate the importance of edge support until they slip off the side of the bed after just sitting down to watch some television.
I define edge support by how sturdy a bed’s sides are. Quality edge support signifies a durable mattress, but also means you can expect the same cushioning and sturdy support you get at the center of the bed’s surface on each of its edges. This is important for couples who need to use the full surface of a bed, and seniors or people with mobility issues who need a sturdy edge to hold on to when getting in or out of bed.
The Helix Moonlight scored an overall 4 out of 5 for edge support, which is good, but we would deem average for a luxury-grade bed like the Moonlight.
Seated test: One of our testers sat on the edge of the Helix Moonlight and assessed how secure they felt. They said, “When I sat down, there was a bit of compression into the top three layers of foam. However, I thought the coils did a nice job of catching me and preventing me from totally sinking in. I think someone could easily sit here and tie a shoe or just take a breather without feeling unstable.” They gave this test a 4.5 out of 5, meaning the Moonlight is likely a good choice if you use your bed for lounging or watching television.
Lying Down test: Here, a tester will rest in multiple sleeping positions along the bed’s edges to determine whether they can expect the same reliable support as in the bed’s center. The tester was impressed by the Helix Moonlight, saying, “I felt very secure when lying on my back, side, and stomach.
Couples should be able to spread out and sleep right up to the edge without issue.” They gave their experience a 4.5 out of 5, and I think this is a good sign that couples could appreciate Helix Moonlight.
Tape measure test: This test involves stacking three different weighted plate sets to resemble a person on the bed’s edges, then measuring how much each set sinks. The lightweight set (99 pounds) sank roughly 3.5 inches and received a 4 out of 5 score. The average-weight plates (154 pounds) sank 4.5 inches and also received a 4 out of 5 score. Finally, the heavyweight set sank 5.5 inches, receiving a 3 out of 5 score.
You can expect quality edge support with the Helix Moonlight, which most likely reflects a durable, sturdy bed in the long term. I would say heavier sleepers may find the edge support a bit lacking, based on the weighted plate set results, but experiences can vary. If edge support seems important to you, you can check out some other beds we’ve reviewed that also demonstrated good edge support.
Helix Moonlight Mattress Performance For Couples
Based on our testing results, the Helix Moonlight is a strong option for couples. The bed received a 4 out of 5 for cooling and responsiveness, and a 4.3 out of 5 for motion isolation, both of which are good signs for couples.
The Helix Moonlight’s motion isolation abilities should help prevent your partner’s movements from waking you up during the night. Furthermore, its cooling features should help prevent the body heat of both people from becoming an issue when sharing the bed. And the bed’s responsive support should offer a good surface to cuddle on or have sex on, without feeling like you’re going to sink into the bed too much.
Overall, I think this is one of the better picks for couples seeking a bed, thanks to its versatility and the performance scores I mentioned. But, if you’re still unsure, you can also check out some of our other suggestions in our 2026 best mattresses for couples review.
Other Performance Factors to Consider
Sex
Considering the Helix Moonlight’s responsiveness, edge support, and noise scores, we gave the mattress a 4.3 out of 5 grade for sex. The bed’s excellent responsiveness, or bounce, should make it easy to move around without feeling trapped in place. Its edge support should also provide pretty reliable full-perimeter support across the entire bed’s surface, especially given the bed’s reinforced coil layer. Moreover, as I’ll describe in the next section, despite having coils, the bed was very quiet when moving around on it and observing noise. So, if you have roommates or children, you won’t have to stress so much about the amount of noise you’re making.
Noise
Our in-house tester gave the Helix Moonlight a 5 out of 5 for noise, as the bed was virtually silent during testing. The tester went so far as to jump up and down on the bed and said, “This bed is very bouncy, so I had to do a jump test and see if the springs made any noise. They did not!”
Base Compatibility
Helix claims its mattresses work well with most standard bed frames, but specifically recommends using its Helix Foundation frame. However, our in-house tester didn’t find the best compatibility with the Helix Moonlight when they tested it on an adjustable base, giving the mattress a 3 out of 5 rating. They explained, “The bed is able to bend, but it doesn’t completely conform to the base. There’s some gapping where the bed isn’t touching the base, especially in TV mode. The more you bend the bed, the more the pillow top bunches up in the middle, which is awkward.”
Durability
When I try to determine a bed’s durability or lifespan, I really focus on its edge support scores, the quality of its materials, and the fine print around the company’s purchase protections.
With the Helix Moonlight, its coiled layer is reinforced lengthwise, and our testers found good edge support (4 out of 5). Helix also offers a limited lifetime warranty, which is generally a strong sign of a company’s confidence in its product’s durability.
Furthermore, despite its competitive pricing, the Helix Moonlight is made in the USA, where manufacturing guidelines are stricter, and uses higher-quality GREENGUARD Gold-certified foams.
I think you can expect a long lifespan from the Helix Moonlight, which I would definitely deem a durable mattress for its price and bed type.

Helix Moonlight Sleeping Position and Body Weight
According to Dr. Dasgupta, “Back sleepers generally benefit from a medium-firm mattress for spinal alignment. Side sleepers find slightly softer mattresses more comfortable for cushioning pressure points. Stomach sleepers need a firmer mattress to prevent back strain. Individual factors like body weight and specific conditions also influence the ideal firmness. It’s crucial to strike a balance that supports your sleeping position while providing comfort.”
Building on Dr. Dasgupta’s point, mattresses are not one-size-fits-all. That’s why we have testers of various sizes try out every mattress we review in different sleeping positions. This allows us to provide a broad understanding of a mattress that is inclusive of all types of sleepers.
Before we dive into our recommendations, though, we want to recognize that people come in all shapes and sizes, and people of every size deserve a mattress that works for their body type. We use the weight categories light, average, and heavy to more easily categorize sleepers based on how mattresses will perform for their body type, as most mattresses are designed for the group we call “average” (130 to 230 pounds).
As a general takeaway, lighter sleepers don’t require as much support as average-weight sleepers, and mattresses will tend to feel firmer to them. On the other hand, heavy sleepers tend to need more support than average-weight sleepers and sink deeper into the mattress. As far as sleeping positions go, side sleepers likely need a softer mattress while stomach sleepers usually need a firmer, more supportive one. Back sleepers are usually somewhere in the middle.
Is the Helix Moonlight a Good Mattress for Light Sleepers (Under 130 pounds)?
- Light Back Sleepers – The Moonlight should work great for lightweight back sleepers. When our lightweight tester tried it on their back, they were pleased, saying, “My back feels fantastic in this position. I’m getting cushioning along my entire body.”
- Light Side Sleepers – The Helix Moonlight’s softer feel should provide great pressure relief and cushioning for lightweight side sleepers. Our lightweight tester said, “I feel pretty weightless overall, and super comfortable to boot.”
- Light Stomach Sleepers – Despite being soft, I think that due to the Helix Moonlight’s bounce and coils, light stomach sleepers should be able to enjoy the mattress.
Is the Helix Moonlight a Good Mattress for Average Weight Sleepers (130–250 pounds)?
- Average-Weight Back Sleepers – I think most average-weight back sleepers will find plenty of spinal support while still enjoying the soft feel of the Helix Moonlight.
- Average-Weight Side Sleepers – I’d recommend the Helix Moonlight for average-weight side sleepers, but they may feel a lack of support due to some sinkage, and need to take a little time to find their sweet spot.
- Average-Weight Stomach Sleepers – According to Dr. Tedesco, the Helix Moonlight isn’t great for stomach sleepers in this category based on his experience, because it’s “too soft”.
Is the Helix Moonlight a Good Mattress for Heavy Sleepers (over 250 pounds)?
- Heavy Back Sleepers – Some heavier back sleepers may enjoy the Helix Moonlight, due to its sturdy support generated from its coiled layer. But because of its softness, they may experience some disruption to their spine’s alignment, as our heavier tester, Caine Wilkes, pointed out: “I’m sinking into the mattress unevenly, and I am just not getting the support that I’d want.”
- Heavy Side Sleepers – I think most heavier side sleepers will sink too much into the Helix Moonlight. When Caine tried out the mattress on his side, he said, “I feel a lot of cushioning on this bed, but there might be a little too much of it. My hips are sinking in much lower than the rest of my body, and I feel like that’s what’s causing pressure buildup.”
- Heavy Stomach Sleepers – Heavier stomach sleepers will most likely find the Helix Moonlight way too soft, and prefer a firmer mattress designed for stomach sleepers.

Helix Moonlight Policies
Dr. Shelby Harris, a Clinical Associate Professor of Neurology and Psychiatry at Albert Einstein College of Medicine, tries to remind mattress shoppers to always “Check if the brand offers a trial period, in case you need to return your mattress if it doesn’t work for you or arrives defective. Keep in mind that every brand is different, and you should always read the fine print regarding warranties and returns before you purchase a new mattress.”
To help alleviate any concerns about future buyer’s remorse, I reviewed Helix Moonlight’s purchase policies to help you understand what you’re getting into.
Warranty: Limited lifetime
Sleep Trial Period: 120 nights
Shipping/Returns: Helix offers free shipping and returns. If you decide the Moonlight mattress isn’t right for you during the initial trial period, Helix will come and pick it up, free of charge.
Helix Moonlight Mattress Vs. Competitors
If you’re still unsure if your lifestyle and sleeping patterns are right for the Helix Moonlight, I lined it up against some of its competitors, so you get a better idea of what’s out there today.
Helix Moonlight vs Brooklyn Bedding Aurora Luxe
The Brooklyn Bedding Aurora Luxe is also a hybrid mattress, but available in three different firmness options (soft, medium, and firm). Our testers experienced better cooling (5 out of 5) and responsiveness (5 out of 5) with the Aurora than with the Helix Moonlight. However, the Aurora Mattress is considerably more expensive than the Moonlight.
- Price: Before discounts, the Brooklyn Bedding Aurora is $2,265 for a queen-size model.
- Sleeping position: With the bed’s multiple firmness options, all sleeper types should be able to find a model that works for them.
- Cooling: Our testers found excellent cooling with the Aurora, giving it a 5 out of 5.
- Body weight: Again, thanks to its multiple firmness options and hybrid build, people of all sizes should be able to find an Aurora model that supports them.

Helix Moonlight vs Saatva Classic
The Saatva Classic is an innerspring mattress, not a hybrid. The Saatva brand carries a lot of weight as a luxury and eco-friendly (organic and recycled materials) brand, and that’s reflected in its pricing. The lack of foam makes the Saatva have considerably worse motion isolation (2.8 out of 5) than the Moonlight. However, the Saatva offers its Classic model in three firmness options.
- Price: The Saatva Classic is currently $2,179 for a queen before any sales or discounts.
- Sleeping position: Despite offering multiple firmness options, the lack of foam layers makes the mattress less ideal for side sleepers and a better pick for back and stomach sleepers.
- Cooling: The Saatva Classic demonstrated similar cooling quality (4 out of 5) as the Moonlight during testing.
- Body weight: The Saatva Classic’s firmness options and innerspring design make it a great choice for average-weight and heavier sleepers. I think many lightweight sleepers will like the Classic, depending on their sleeping patterns, but lightweight side sleepers may struggle to find a model soft enough.

Helix Moonlight vs Nolah Evolution
The Nolah Evolution stands taller than the Moonlight at 15 inches and features a hybrid design. What stood out most during testing was the bed’s better motion isolation (5 out of 5) and edge support (4.6 out of 5), which may make the Nolah Evolution a slightly better choice for couples.
- Price: At the time of writing, the Nolah Evolution is $2,277 before discounts for a queen.
- Sleeping position: Our testers found the Nolah Evolution worked best for lightweight and average-weight side and back sleepers.
- Cooling: The Nolah Evolution has slightly better cooling (4.5 out of 5) than the Moonlight.
- Body weight: Heavier back and stomach sleepers may find the Nolah Evolution not firm enough, despite its three firmness options.

Other Models from Helix
The Helix Moonlight is one of many mattresses offered by Helix. The Moonlight specializes in offering a softer hybrid feel with back and stomach sleepers in mind. Below, I’ll compare the Helix Moonlight to some of the other beds Helix produces that we’ve reviewed.
Helix Moonlight vs Helix Midnight
The two Helix mattresses are quite similar in design (hybrids), but the Helix Midnight runs a bit firmer than the Moonlight, making it more ideal for some back sleepers. Performance scores were quite similar. However, the Helix Midnight demonstrated slightly better responsiveness (4.5 out of 5).
- Price: The Helix Midnight and Moonlight are both right around $1,000.
- Sleeping position: Back and stomach sleepers may find the Midnight a slightly better choice due to its firmer firmness. However, the Helix Moonlight may offer better contouring.
- Cooling: The Helix Midnight received a lower-quality cooling rating (3.5 out of 5) than the Helix Moonlight during testing.
- Body weight: Heavier sleepers will likely find the Helix Midnight does not offer enough support, especially heavier stomach sleepers.

Helix Moonlight vs Helix Sunset Luxe
The Helix Sunset Luxe and Helix Moonlight are also very similar, but the Sunset Luxe is more expensive, has zoned support, and is slightly firmer. Despite its higher price, we found that the Helix Moonlight actually outperformed the Sunset Luxe in cooling, edge support, and motion isolation.
- Price: The Helix Sunset Luxe is $2,400 before discounts for a queen.
- Sleeping position: Back and stomach sleepers may appreciate the Sunset Luxe’s firmer feel, even if just slightly firmer than the Moonlight.
- Cooling: The Helix Sunset Luxe got a 3.5 out of 5 by our testers for temperature regulation, which wouldn’t make it a better choice than the Helix Moonlight for hot sleepers.
- Body weight: Because the Helix Sunset Luxe is firmer than Helix’s Moonlight, it may be more accessible to heavier sleepers. Lighter sleepers may appreciate the Moonlight more, though, due to its softer feel.

Helix Moonlight vs Helix Dusk
The Helix Dusk is also a hybrid mattress, but considerably firmer than the Moonlight (8 out of 10 on our firmness scale). The Dusk is better suited to back and stomach sleepers, as well as heavier sleepers, than the Helix Moonlight.
- Price: A queen-size Helix Dusk mattress costs $999, similar to the Moonlight.
- Sleeping position: Back and stomach sleepers will appreciate the Helix Dusk’s firmer support layers.
- Cooling: Our testers gave the Helix Dusk a 4.5 out of 5 for cooling.
- Body weight: Lightweight sleepers, especially lightweight side sleepers, may find the Helix Dusk too firm for adequate pressure relief.

Helix Moonlight Mattress Policies and FAQs
How firm is the Helix Moonlight and who is it best for?
We gave the Helix Moonlight a 6 out of 10 firmness rating. I’d say this firmness level is best suited for lightweight and average-weight side and back sleepers.
Does the Helix Moonlight have a sleep trial?
Yes, the Helix Moonlight offers a 120-night sleep trial, with a free return and full refund if you don’t like your mattress during this testing period. I do suggest giving your mattress at least a month to break in after unboxing, to ensure it has fully expanded and any off-gassing is finished.
Notably, this sleep trial only applies to Helix mattresses and not all Helix sleep products, such as their bedding or pillows, which usually include a 30-night trial.
Can I return the Helix Moonlight if I don’t like it?
Yes, you can return your mattress for a full refund during the initial 120-night sleep trial if you don’t like it. Notably, this policy applies to all of Helix’s online mattresses, including the luxe version of the Moonlight (the Helix Moonlight Luxe), as well as other Helix mattresses and luxe models, such as the Helix Twilight, Helix Midnight Luxe, and Helix Dawn.
