Helix Sunset Mattress Review

Helix Sleep makes hybrid bed-in-a-box mattresses to suit any body type. Their line includes six standard models and six Luxe models (and a Plus model made for heavy people). You can find out about all of these models in our Helix mattress review and Helix Luxe mattress review. But if you’re interested in the Helix Sunset, the brand’s softest model, or the Helix Sunset Luxe, Helix’s luxury version of this mattress, you’re in the right place!

In this review, I’ll tell you more about both Sunset models, let you know which sleepers I’d recommend them to, and put them through some tests. Stay tuned to learn if one of these soft memory foam hybrids could work for you, or skip down to my review summary to save time.

Is the Helix Sunset a Good Mattress for You?

Before I get into all the details, I want to give you a general overview of who the Helix Sunset and Helix Sunset Luxe might work best for. The Sunset Luxe is very similar to the standard Sunset model, but it’s 2 inches thicker, uses zoned support (more on that below), and has a more cooling cover than the standard model. Both models should work for similar sleepers.

Who I recommend the Helix Sunset mattress for

  • Both these beds are really soft, which makes them great options for side sleepers looking for a soft, contouring feel.
  • Thanks to their memory foam layers, the Helix Sunset models also provide the cushiony, sinking feeling that memory foam fans really enjoy.
  • If you struggle with joint pain the Sunset line could be a great solution for you! These soft beds offer plenty of relief for sensitive pressure points and joints.

Who I don’t recommend the Helix Sunset mattress for

  • These beds are not great options for strict stomach sleepers. I’d recommend these folks check out our best mattresses for stomach sleepers or opt for a firmer Helix model.
  • Couples might find that they’re too easily disturbed by their partners on the standard Helix Sunset mattress, which doesn’t offer much motion isolation. The thicker Sunset Luxe is the better option for these sleepers.
  • Heavy sleepers (over 250 lbs) won’t get the durability or support they need from the soft Helix Sunset mattresses. I’d recommend they check out the Helix Plus or consider one of our best mattresses for heavy people.

How Firm is the Helix Sunset Mattress?

Next, let’s get into what you really want to know before buying a new mattress: feel! Keep in mind that feel is subjective, and is influenced by your body weight, shape, and preferred sleeping position. For reference, I’m around 5’10” and 190 lbs, and I sleep on my stomach. So, my firmness rating might vary a little from your own.

I tested the Sunset and the Sunset Luxe, and thought they felt quite similar. I gave both of these beds a firmness rating of 5.5 out of 10 on the mattress firmness scale. The industry standard for medium firmness is a 6.5 out of 10, which means these are soft mattresses.

The soft feeling Helix Sunset Luxe.

The standard Sunset has a typical memory foam feel that should work well for back and side sleepers. It did a great job of alleviating uncomfortable pressure pressure on joints like the shoulders, hips, and knees. Generally speaking, I would not recommend this mattress for stomach sleepers like myself—most stomach sleepers need a more supportive mattress to keep their spine safely and comfortably aligned at night.

Helix Sunset Back Sleepers
Back sleepers that like a softer feel should like the Sunset.

Like the standard Sunset, the Sunset Luxe had a soft, contouring feel. But its zoned lumbar support system offered a bit of extra support around my hips and lower back. So back sleepers who struggle with back pain might prefer the Luxe model. The Luxe is also a bit thicker thanks to its gel visco pillow top, so if you prefer an extra-luxurious feel the Luxe is the way to go.

Helix Sunset Mattress Performance

Firmness is an important factor to consider when selecting a mattress, but it’s not everything. I also conducted some tests to see how the Helix Sunset performs for several different sleeper types. You’ll see the results of the standard model’s tests in the graphics below.

Testing the Helix Sunset Mattress in Different Sleeping Positions

A mattress will feel different to you depending on your body weight and preferred sleeping position. Below, I’ve broken down how the Sunset will perform for several different sleeper types.

Is the Helix Sunset a Good Mattress for Light Sleepers (Under 130 lbs)?

  • Light Back Sleepers – Lightweight back sleepers should really like both Sunset models. They’ll get plenty of contouring around the lower back on these beds.
  • Light Side Sleepers – Both of these beds are also good fits for light side sleepers. They’ll offer plenty of sinkage and pressure relief to these folks.
  • Light Stomach Sleepers – I’d steer these sleepers to a firmer model, like the Helix Dawn, to ensure they’re getting proper lumbar support.

Is the Helix Sunset a Good Mattress for Average Weight Sleepers (130 – 250 lbs)?

  • Average Weight Back Sleepers – Both Sunset models are good picks for these sleepers, their foam layers really alleviate tension at the lower back.
  • Average Weight Side Sleepers – These sleepers should really like both Sunset models. They’ll get plenty of cushioning around sensitive joints on these beds.
  • Average Weight Stomach Sleepers – Because both Sunset models feel so soft and plushy, I wouldn’t recommend them to these sleepers. Stomach sleepers generally fare better on a firm mattress that prevents their hips from sinking into the bed.

Is the Helix Sunset a Good Mattress for Heavy Sleepers (over 250 lbs)?

If you’re on the heavier side, you’re likely to sink further into the Sunset mattresses and experience more pressure in each sleeping position. I wouldn’t recommend either of the Sunset beds for an above-average weight sleeper, their coil layers are not quite firm enough to support them. Instead, I’d recommend an innerspring mattress with a firm feel or the Helix Plus mattress.

Helix Sunset Mattress Pain Relief Performance

Pain relief is a major feel factor, as a mattress that relieves pain will ensure you’re comfortable all night without hurting your hips, knees, shoulders, and lower back. In order to test a mattress’s pain relief capabilities, I use a pressure map. It’s a mat device I can roll out on top of a mattress. When I lie down on it, the map measures how much force my body exerts onto the bed. It then produces a pressure map for visual help—areas of low pressure are blue to green, and areas of high pressure come up yellow to red. Lower pressure means less pain!

Helix Sunset Pressure Relief
I was impressed with the pressure relief at the shoulders on the Helix Sunset.

Back Pain — Based on the pressure maps above, the Helix Sunset models could do a great job alleviating tension and pressure at the lower back. But, I’d personally recommend folks with back pain opt for a slightly firmer mattress to help them maintain a neutral spinal alignment.

Shoulder Pain — The pressure map created from lying on my side was largely blue, with areas of slightly more pressure around the hips and shoulders. Overall, this map suggests that the mattress does a great job alleviating pressure at the shoulders. The Luxe should alleviate even more pressure around the shoulders, which might be nice for particularly sensitive folks.

The Sunset Luxe is a great choice for side sleepers with sensitive joints.

Hip Pain — Similarly, the Sunset should feel comfortable to folks with hip pain. But I’d recommend the more cushioning Sunset Luxe to these sleepers based on the amount of green in the pressure map above.

Helix Sunset Mattress Performance for Couples

Couples tend to do best on mattresses with good motion isolation, enough responsiveness for sex, cooling features, and strong edge support. Read on below to learn more about these terms and find out how the Sunset mattress stacks up.

Motion Transfer

Motion transfer is a measure of how much movement you can detect from one side of the bed while resting on the other, and mimics what you might feel if you sleep with a partner who moves around at night.

To test motion transfer, I dropped a 10 lb steel ball onto the mattress from three different heights and used a seismometer to measure how much disturbance it caused. Each of the three heights is meant to mimic a different movement.

Helix Sunset Motion Transfer
Motion transfer test results for the Helix Sunset.

In my opinion, the results from the motion transfer test on the Helix Sunset were not great. The smallest drop caused a medium disturbance, and the other drops showed pretty major disruption. For those reasons, the Helix Sunset would not necessarily be my first choice for light sleepers, or people who sleep with particularly rambunctious partners or pets!

On the other hand, the Sunset Luxe’s quilted pillow top offered a little more motion isolation. Thanks to this top layer the Sunset Luxe offers more of the motion isolation you might expect from a memory foam mattress. I’d opt for the Luxe model if you sleep with a partner.


Most mattresses with low motion transfer scores are not great for sex, because it’s difficult to move around and change positions on these beds. Couples often want a mattress that balances motion transfer and responsiveness. I’d say both Sunset models do a fairly good job of this. It shouldn’t be too difficult to move around on these hybrids. But, if you’re looking for a lot of responsiveness, I’d opt for a more medium-firm feel and avoid beds with memory foam top layers.


Couples overheat more quickly than solo sleepers, so often prefer cooling mattresses. Luckily, both Sunset mattresses sleep cool. The Sunset Luxe includes more cooling materials than the standard model, so particularly hot sleepers should opt for that mattress.

Edge Support

Edge support is a measure of how supported you’ll feel on the side of your bed as compared to in the center. Great edge support makes a bed feel larger, which is a perk for couples. The Sunset models both had average edge support, which is what I’d expect from softer beds like these.

What is the Helix Sunset Mattress Made Of?

The Helix Sunset is a hybrid mattress, combining pocketed coils with foam layers. It has a soft, breathable cover, a layer of memory foam for a nice, contouring feel, individually wrapped coils, strong edge support, and a supportive base layer. Below, I’ll take you through the Sunset and the Sunset Luxe layer-by-layer.

Helix Sunset

Cover — The 100% polyester soft touch design cover is designed to promote airflow, which can help prevent overheating at night. It feels soft and breathable.

Comfort Layer — Below the cover, there’s a layer of Memory Plus Foam. This foam is designed to relieve joint pressure for total comfort throughout the night. The special Helix-blend foam cushions the body and has a comfy, soft feel.

Transition Layer — The transition layer of the Helix Sunset mattress is made with Helix Dynamic Foam, which provides a soft, cushioning feel and some good ergonomic support.

Support Layer — Next up is the body shape layer, made of hundreds of individually wrapped wire coils. These coils provide a cradling feeling, and also add a nice bouncy feel to the bed. They are also reinforced around the perimeter of the mattress to provide solid edge support.

Base Layer — The final layer of the mattress is made with DuraDense Foam, a type of polyfoam that supports the entire mattress on top of a slatted bed frame or box spring.

Helix Sunset Luxe

Cover — The Sunset Luxe’s mattress cover is made of eco-friendly Tencel and offers even more breathability than the standard Sunset’s cover.

Pillow Top — The top layer of the Luxe is quilted with gel foam to offer even more body-contouring and a nice plush feel.

Comfort Layer — Next up is the same Memory Plus foam that’s in the standard model!

Transition Layer — Below that is the same Helix Dynamic foam that the standard model offers.

Contour Layer — The Luxe adds an additional high-grade polyfoam layer to provide deeper body contouring.

Support Layer — Next up is a pocketed coil layer. The Luxe includes more coils than the standard Sunset and these coils are zoned for support, which means they’ll feel firmer at the lower back and softer at the shoulders.

Base Layer — Last up is the same layer of DuraDense Foam you can find in the standard model.

Helix Sunset Unboxing and Off-Gassing

The Sunset and Sunset Luxe are both bed-in-a-box mattresses, which means both will have  an off-gassing and decompression period after they’re unwrapped. Be sure to leave either of these beds in a well-ventilated room during off-gassing to ensure any odor dissipates within 24-48 hours. You may also want to make sure you have a friend nearby to help you unbox the Sunset Luxe, which is a heavy bed.

My Final Thoughts about the Helix Sunset Mattress

Now that we’ve covered what’s inside the Helix Sunset mattresses, how it feels to sleep on them, and how they performed in our various tests, I can list a few things for you to consider when deciding if the Helix Sunset is the right choice for you or not.

My favorite things about the Helix Sunset mattress

Both of the Sunset mattresses are great options for side sleepers. The firmness level of these beds mean they’ll offer plenty of plush pressure relief to these folks. I also think these beds are great picks for side sleepers who sleep hot. The Sunset Luxe especially does a great job of temperature regulation thanks to its cooling cover, gel-infused foams, and breathable pocketed coils. I’d highly recommend any memory foam lovers take a look at the Helix Sunset line.

My Helix Sunset mattress complaints

That said, these mattresses are definitely too soft for stomach sleepers. Back sleepers who like a firmer feel might also find these beds a bit too soft. But if a hybrid mattress with a body-contouring foam layer is appealing to you, Helix offers plenty of different models, so you should be able to find one that works for you.

I’ve also noticed that Helix mattresses do have a strong off-gassing smell when you take them out of the box. But, most bed-in-a-box mattresses have an off-gassing period. If you’re concerned about odor leave your new mattress in a well-ventilated room for at least one day before adding sheets.
