The Good Housekeeping team has evaluated a few Helix mattresses in the Good Housekeeping Institute Textiles Lab, analyzing over 1,200 data points to offer a comprehensive review of what you can expect from a Helix mattress. Check out the full review here are scroll down to see what the found: 

Helix Midnight Luxe 

Performance 

Helix's best-selling mattress is the Midnight Luxe. It's made for side sleepers, the most common sleeping position, and has the same medium level of firmness as the Dusk Luxe along with the built-in Euro top. Our testers, including side sleepers and side-back combo sleepers, gave the model high scores across the board. I've tried out the Midnight Luxe, and it's not hard to see why it's a crowd favorite.

It has a classic foam hybrid feel: The foam contours to the shape of your body and cradles pressure points. Those who like the feel of soft memory foam will love the way this mattress cushions their bodies rather than crushing it, like traditional firm innerspring beds might, but users who prefer to feel like they're sleeping "on top of" their beds may find it less than ideal.

Overall comfort & support

As expected, the Midnight Luxe was especially popular among side sleepers on our panel who appreciated the comfortable pillow top and cushioned feel. One consumer tester noted, "I like how my shoulder and arm sink into the mattress, so I don't feel pain in my shoulder." Others agreed: "I love this mattress! I sink into it as I sleep, making it feel comfortable and cloud-like," said one combination sleeper. "I sleep with my partner and we both really like how it feels when we lay in all positions — side, stomach and back." She also noted that as someone with a large bust, she finds it comfortable even when sleeping on her stomach. 

The Midnight Luxe has a true medium feel, so if you're a side sleeper looking for something a little more plush (which was the case for some survey panelists), consider the Sunset Luxe instead. 

Edge support

It's similar to the Dusk Luxe with medium edge support. One of our reviewers summarized, "the edge of the bed definitely sinks in, but not so much that you can't sit on the edge."

Motion isolation

Since the Midnight Luxe has a classic foam hybrid feel, there isn't much bounce. As a result, it has great motion isolation. One tester shared, "I don't feel [my partner's] tossing and turning as much as I did with our previous mattress, which is a game changer — seriously." 

Temperature

Our reviewers were divided on whether they maintained a comfortable body temperature on this bed. While there weren't any complaints, users gave it moderate scores overall. One tester with the cooling cover version commented that while she hasn't felt as hot or sweaty at night, "it doesn't feel particularly cool." 

Materials

The 13.5-inch Midnight Luxe is comprised of foam layers on top of coils.

Helix Dusk Luxe 

The Dusk Luxe is our pick for the best mattress for couples because it's combination sleeper-friendly and has a versatile medium firmness. It earned high scores from testers and panel members alike and remains one of the brand's most popular mattresses, second only to the Midnight Luxe (which we discuss further below). We also like the comfortable, built-in Euro top, which is rare to see on a boxed bed.

The mattress is designed for back and stomach sleepers and has a responsive feel with a bit more bounce than your average hybrid. Lying down on the Dusk Luxe (with the cooling Glacio-Tex cover rather than the standard Tencel lyocell cover) for the first time, I remember feeling immediately comfortable and didn't want to get up. It had a luxurious, pillow-top texture with a textbook medium firmness feel.

Overall comfort & support

Our reviewers, especially couples and combination sleepers, appreciate the balanced, supportive feel of the Dusk Luxe. "The mattress is contouring but feels supportive under pressure points," said one tester. "I like that the mattress is soft and conforming enough for [sleeping on my back] and supportive enough for side or [stomach] sleeping." Another user told us it was a good fit for her as a side sleeper and her partner, a back sleeper. She described the bed as "not too soft so you don't sink in, but not so hard that it doesn't move to best support you." Others commented on how easy it was to switch positions at night and spoke highly of the comfortable depth.

Still, a few wished it was a bit more firm. If you prefer a firmer bed, we recommend the Dawn Luxe. 

Edge support

Helix's Dusk Luxe is a hybrid mattress with several layers of foam on top of coils. Typically, innerspring mattresses have excellent edge support, whereas foam mattresses struggle to provide the same sturdy edges. Our reviewers don't always agree on Dusk Luxe here: Some find the edge support much better than other beds they've tried, while other reviewers say it leaves much to be desired. I personally found it middle of the road — I've encountered mattresses with much worse edge support, but it's not particularly noteworthy.

Motion isolation

While innerspring mattresses often have poor motion isolation and foam mattresses isolate and absorb any motion, rather than transferring it, hybrid mattresses fall somewhere in the middle. Most of our testers and panelists found the motion isolation adequate, but some noted they could feel movement if their partner was too close to them in the bed. 

Temperature

Memory foam, which is used in the top layers of the Dusk Luxe, is notorious for trapping heat while innerspring coils can help provide breathability. A hybrid bed, once again, falls in the middle, making it a nice compromise. Testers who previously slept on foam beds noticed improved sleep. "The first night we had the Helix, I didn't wake up sweaty at all and woke up feeling more refreshed than I had in months. It felt like a revelation," said one. Still, while it sleeps cooler than a memory foam mattress, it isn't the coolest mattress on the market. Helix also offers the option to add on a cool-to-the-touch GlacioTex cover for an extra fee, which one of our reviewers is currently in the process of testing.

Materials

Like most hybrids, the 13.5-inch Dusk Luxe combines layers of foam with a coil base.
