Boasting a soft and breathable feel, the Helix Moonlight is a hybrid mattress with both foam and coil layers. It’s soft to lie on, but has a little bounce to it, too. This mattress is one of the softer models Helix offers, and it has a ton of great reviews! So, I had to test it out for myself to see if it lives up to the hype.
Keep reading to find out everything you need to know about the Helix Moonlight, including construction details, what type of sleeper it’s best for, and how it truly feels.
Helix Sleep was launched in 2015, and the NYC-based company currently offers a selection of mattresses, pillows, toppers, bedding, bases, and more! The company also owns Birch by Helix, a line of mattresses made with 100% organic-certified materials, and Allform by Helix, which is a line of modular sofas.
The Helix Moonlight is one mattress in a collection that also encompasses the Helix Sunset, Helix Midnight, Helix Dusk, Helix Dawn, and Helix Twilight. To learn more about these mattresses, check out our main Helix mattress review where we break down each model!
What is the Helix Moonlight Mattress Made Of?
The Helix Moonlight is a hybrid mattress, meaning it combines foam layers with pocketed coils for a soft and bouncy feel. Plus, a reinforced perimeter in the pocketed coil layer adds awesome edge support, which means you won’t slide off the bed if you get too close to the side.
Here’s what’s inside the mattress, layer by layer.
Cover – The Helix Soft Touch mattress cover is made entirely of polyester, so has a nice, breathable feel to it. This increased airflow helps to establish a cooling tone for the mattress.
Comfort – Just below the cover is a comfort layer of Helix Dynamic Foam, which is a latex hybrid-foam alternative designed to contour to your body. This isn’t memory foam, so it won’t provide that “sinking” feeling some people love. Instead, it feels more like a gentle cushioning with a bit of lift and bounce.
Transition – This layer is also made of Helix Dynamic Foam, providing your body with ergonomic support that’s still soft and comfortable.
Base – First up is the body shape layer, which contains individually-wrapped coils for bounce and mobility. The layer of coils has a reinforced perimeter for edge support, meaning you can roll right to the edge of the bed without worrying about sliding off! Beneath the coils, you’ll find a base layer built of DuraDense foam, providing the mattress with support and stability.
How Does the Helix Moonlight Mattress Feel?
So, now we know what the Helix Moonlight mattress is made of, it’s time to go over how it actually feels, starting with firmness.
As with any feel factor, firmness can be quite subjective depending on your body composition and how you like to sleep. For reference, I’m a stomach sleeper and around 5’10” and 190 lbs.
After lying on this mattress for a while, I decided to give it a firmness rating of 5.5/10. Given that the industry standard is a 6.5 rating for medium firmness, my rating confirms that this bed is quite soft.
This lines up with the description of the Helix Moonlight as one of the softer models in the six-mattress line. I gave this mattress a 5.5 because the Helix Dynamic Foam established a soft and plushy feel that really cushioned around my body for extra comfort.
A soft mattress like this is generally a good bet for side sleepers who want to avoid uncomfortable pressure on their shoulders and hips. It could also work well for back sleepers who prefer a softer feel. That said, they are not typically great for stomach sleepers who need extra support to keep their spine aligned while they sleep. And if you’re looking for something super soft, you can always add a cushy pillow-top mattress cover to any mattress you like.
Testing the Helix Moonlight Mattress
While mattress firmness is important, it isn’t everything. As well as rating the firmness of the Helix Moonlight, I conducted a few specific tests to see just how the Helix Moonlight performs for pressure relief and motion transfer.
To get a sense of how the mattress relieves pressure on potentially sensitive spots like your joints and lower back, I used my trusty pressure map.
How does it work? Well, it’s actually pretty simple. After setting up the device map on top of the mattress, I rolled around on it to see how much force my body exerted on the structure. The device creates a color-coded map of that pressure, where blue areas show low pressure and red areas show high pressure.
Back – The Helix Moonlight will probably work well for back sleepers; as you can see, the pressure map is almost entirely blue, with just a touch more pressure around the lower back and hip area. The comfort foam layers offer some pleasing pressure relief, especially around the shoulder and neck area.
Side – The mostly blue pressure map here shows that the Helix Moonlight is a pretty ideal choice for side sleepers. There was some slight pressure on my hips and shoulders, but it was still at the lower end. Overall, I was comfortable lying on my side.
Stomach – In my opinion, the Helix Moonlight is too soft for strict stomach sleepers. Generally speaking, a strict stomach sleeper would fare better with a firmer mattress, which can support the spine and position the body really soundly atop the mattress.
I also tested this mattress for motion transfer—basically, how much movement you can feel from one side of the bed when you’re resting on the other. This is something relevant to all sleepers, but it’s particularly crucial for anyone sharing their bed with a partner or a pet who might move around at night.
Our motion transfer test involves dropping a 10 lb. steel ball onto the mattress from three different heights (four inches, eight inches, and 12 inches) and measuring the type of disturbance it causes using a seismometer.
These are some pretty middling results, suggesting that you may well be disturbed by motion transfer (unless you’re a super heavy sleeper, of course). Given that the Helix Moonlight doesn’t have a memory foam comfort layer, which goes a long way to isolate movement, this isn’t super surprising! That means that the Helix Mattress is not necessarily ideal for light sleepers who aren’t alone in the bed. If low motion transfer is a priority for you, there are three other Helix mattreses in this line that perform better in this test due to their memory foam comfort layers—the Helix Sunset, Helix Midnight, and Helix Twilight.
Should You Buy the Helix Moonlight Mattress?
The Helix Moonlight is a hybrid mattress that uses soft foams for pressure relief and pocketed coil support for some added bounce. The gentle feel is great for side sleepers and the bouncy coils mean you won’t feel stuck in the mattress while trying to change positions.
Helix Moonlight Pros
- I really like this mattress for side sleepers, as it didn’t put too much pressure on my shoulders or hips!
- The hybrid build is super bouncy, which makes for a really pleasant feel—and you can change positions without feeling “stuck” in the mattress.
Helix Moonlight Complaints
- I also would not recommend this bed for stomach sleepers. I think the model is just too soft! Most stomach sleepers will need a firm mattress that keeps their hips in line with their shoulders—with this mattress you’re likely to find your hips sinking down into the bed, throwing your spine out of alignment and potentially causing some aches and pains down the line.
