Helix is a direct-to-consumer mattress company known for its sleep quiz. This quiz recommends a mattress model based on the customer’s weight, sleep position, and personal preferences. To accommodate a wide range of sleep styles, the standard Helix line consists of seven hybrid models.

Each standard Helix mattress has a distinct firmness level and is designed for a different type of sleeper. The Sunset (a 3 on our 10-point firmness scale), Midnight (6), and Twilight (7) are intended for side sleepers. The Moonlight (4), Dusk (6), and Dawn (8) are geared toward back and stomach sleepers. The seventh model, the Helix Plus (7), was created for any sleeper who weighs more than 230 pounds.

While each Helix mattress is intended for specific sleeper types, our tests show some of these hybrids appeal to sleepers who fall outside their target groups.

In addition to the standard versions, each model except for the Plus is also available in Luxe and Elite versions. These optional upgrades add extra comfort layers, zoned lumbar support in the coil system, and specialty cooling covers. Helix also offers the Helix Kids mattress for children between the ages of 3 and 12.

We’ll take a closer look at all seven standard Helix mattress models and discuss their materials, performance, and customer ratings. We’ll also highlight the potential benefits of each model to give you a clearer idea of which option may be best for you.

Testing Team Takeaways

To test Helix mattresses, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.

The phrase “something for everyone” gets thrown around a lot, but with Helix this is truly the case. You can choose from a wide range of hybrids ranging from affordable to high-end, and each one is designed for certain sleepers based on their weight and preferred position. As a side sleeper, I personally prefer the Midnight and Dawn — take the Helix Sleep Quiz to figure out your best match.

What Helix gets so spot on is in their understanding that comfort is not universal, mattress firmness is personal. Outside of being tailored to your preferences and needs, I think the Helix beds are really well-rounded — they do so many things well from a quality support system, pressure relieving comfort layers that also don’t lead to heat buildup.

Side Sleepers

Our tests suggest most side sleepers will find the Sunset, Midnight, and Twilight mattresses most comfortable. These findings are in line with Helix’s intended designs. Side sleepers on our team weighing up to 230 pounds awarded high ratings to the Sunset and Midnight, while those over 230 pounds preferred the Twilight. We also found the Moonlight — while meant for back and stomach sleepers — contours closely and should provide adequate cushioning for most side sleepers who weigh 230 pounds or less.

Side sleeping generally requires more cushioning than other sleep positions. Extra padding beneath the shoulders and hips is key because these areas are prone to pressure buildup. A sturdy support system is also needed to promote even alignment.

Back Sleepers

Our testing team found that back sleepers weighing less than 130 pounds felt comfortable on many of the standard Helix models, but ultimately gave their most favorable ratings to the Moonlight. Back sleepers between 130 and 230 pounds preferred the Dusk and Midnight with the Twilight coming in at a close second. For back sleepers over 230 pounds, the Plus and Dusk received the highest marks.

We’ve found back sleepers usually prefer medium firm to firm mattresses. Sturdy support prevents them from sinking too deeply into the mattress, while some cushioning on the surface can alleviate pressure points and sore spots.

Stomach Sleepers

Stomach sleepers on our testing team under 130 pounds found the Moonlight most comfortable among the seven standard Helix hybrids. Our stomach sleepers between 130 and 230 pounds were more partial to the Dusk and Twilight, while those over 230 pounds preferred the Dawn, Plus, and Twilight. 

Stomach sleepers often need firmer mattresses than other types of sleepers in the same weight group. This is because lying face down exerts a lot of compression on the mattress. Without sturdy reinforcement, stomach sleepers can sink excessively and experience neck and lower back pain.

Helix Mattress Performance

In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.

Motion Isolation

7.5 / 10

Helix Moonlight: 6.5 / 10

Helix Dusk: 8 / 10

Helix Dawn: 6.5 / 10

Helix Sunset: 8 / 10

Helix Midnight: 6.5 / 10

Helix Twilight: 5.5 / 10

Helix Plus: 8 / 10

Each Helix mattress isolates motion to a different degree. Our team found that the Sunset and Moonlight reduce the most motion transfer, while the firmer models don’t absorb movement as well. — Danny

Most Helix hybrids isolate motion well thanks to their thick foam layers. The Dusk and Sunset absorb the most motion of all the Helix models. The Plus also has a two-layer comfort system that limits the spread of vibrations across the mattress surface.

The Moonlight, Dawn, and Midnight produce some motion transfer, but probably not enough to cause too many sleep disruptions.

Pressure Relief

8.5 / 10

Helix Moonlight: 8 / 10

Helix Dusk: 8 / 10

Helix Dawn: 6.5 / 10

Helix Sunset: 8 / 10

Helix Midnight: 8 / 10

Helix Twilight: 6.5 / 10

Helix Plus: 8 / 10

The softer Helix models – the Sunset, the Moonlight, and the Midnight – are where you’ll get the best pressure-relieving cradle. I find each of these models have a nice soft hug for my shoulder and hip areas, which allows an effective amount of sink. I weigh around 180 lbs and very much prefer softer feeling beds, so these three Helix models are what I would choose when it comes to pressure relief, but your mileage may vary depending on your weight and body profile. — Jackson

Most Helix mattresses alleviate pressure well for their intended weight groups. Our tests show The Moonlight, Dusk, Sunset, and Midnight offer the best pressure relief thanks in part to the plusher surfaces. The Plus is constructed specifically for larger individuals, and it can relieve pressure points very well for sleepers in this group.

The firmer Dawn and Twilight push back more strongly against your pressure points, lowering their performance ratings in this category.

Temperature Control

8 / 10

Helix Moonlight: 6.5 / 10

Helix Dusk: 6.5 / 10

Helix Dawn: 8 / 10

Helix Sunset: 6.5 / 10

Helix Midnight: 6.5 / 10

Helix Twilight: 6.5 / 10

Helix Plus: 6.5 / 10

Like a lot of foam hybrids we’ve tested, I felt some heat on the standard Helix mattresses — not an excessive amount, but noticeable all the same. If you run hot in bed and don’t mind paying a little extra, I recommend the cooling cover upgrade. This add-on makes a huge difference in the surface temperature. — Brad

The Helix mattresses perform about average for hybrids when it comes to sleeping cool. Memory foam is well-known for its tendency to sleep hot, as it often traps and retains heat through the night, but the coil cores of these beds promote airflow to help balance out heat retention. The Dawn sleeps a bit cooler than the other models thanks to its firm feel.

You can upgrade any standard Helix hybrid to include a cooling pillow-top layer encased in GlacioTex fabric. This material dissipates body heat on contact, so the upgrade may be a good idea if you are prone to sleeping hot.

Edge Support

8 / 10

Helix Moonlight: 5.5 / 10

Helix Dusk: 6.5 / 10

Helix Dawn: 8 / 10

Helix Sunset: 5.5 / 10

Helix Midnight: 6.5 / 10

Helix Twilight: 8 / 10

Helix Plus: 6.5 / 10

Each Helix mattress has a reinforced perimeter, so you’ll notice extra coil pushback when you get in and out of bed, but the Twilight, Dawn, and Plus models received our highest scores during hands-on tests. — Danny

Standard Helix models all have a reinforced perimeter within the coil core, which helps to limit the amount of sinkage that occurs when a person sits or sleeps near the edge of the bed. However, each model varies in the degree of edge support it provides depending largely on its firmness and construction. The Dawn and Twilight offer the best edge support due to their firm designs. The Dusk, Midnight, and Plus also offer decent perimeter support along the perimeter.

The Moonlight and Sunset are the plushest models, which means you will sink more easily while sitting or sleeping near the edge. These models earned the lowest edge support ratings among all of the standard Helix mattresses.

Ease of Movement

7 / 10

Helix Moonlight: 5.5 / 10

Helix Dusk: 6.5 / 10

Helix Dawn: 8 / 10

Helix Sunset: 5.5 / 10

Helix Midnight: 6.5 / 10

Helix Twilight: 8 / 10

Helix Plus: 6.5 / 10

Movement across the surface of the bed depends which Helix model you’re on. The softer makes are pretty prone to trapping movement, but the firmer builds are quite good at allowing you to move freely. This is one of those sink-in vs. float-on-top factors that Helix is so good at creating personalization for within its mattress line. — Jackson

Ease of movement is another category that is largely distinguished by the firmness of each model. The softer Moonlight and Sunset contour closely and sink quite a bit, making it difficult to move across their surfaces. In contrast, the Dawn and Twilight models provide sturdy pushback against the body to help you move around and get out of bed easily. Conforming from the Plus’ two-layer comfort system may make the bed slightly more challenging to move on than other hybrids, but the firm feel still offers decent ease of movement.

Off-Gassing

7.5 / 10

Helix mattresses produce a strong odor straight out of the box — this comes from the foam layers. The smells will probably linger for a couple days, then completely dissipate. Airing out your Helix in a well-ventilated room can speed along this process. — Brad

Like any mattress that uses foam, all the Helix models produce an average amount of “new mattress smell” at first. This odor is generally considered to be harmless, and should dissipate within a few days. The Helix mattresses are all hybrid models, so their coil cores allow for more air to flow through the mattress. Any off-gassing odors should air out faster than they would with an all-foam mattress.

If you find the smell unpleasant, consider letting the mattress sit in a well-ventilated room for a few hours after opening.

Mattress Construction

Standard Helix mattresses feature a hybrid design that pairs foam comfort and transition layers with a coil core. All models share a similar construction with some slight variations. Below is a breakdown of each mattress construction.
