Robust design that supports up to 1,000 pounds
Reliable edge support
Provides a flat and supportive sleep surface that’s great for back and stomach sleepers
Cons
Not an ideal fit for sleepers who want deep contouring
Movement on one side of the mattress causes vibrations on the other side
The Helix Plus Mattress is geared toward sleepers who require strong support from their bed. Its sturdy, dependable design is engineered to accommodate up to 1,000 pounds of body weight.
With a hybrid construction, two foam layers lightly cushion the body and thick coils provide a steady base of support. Optional add-ons include a cooling cover with a quilted pillow-top.
We brought the Helix Plus into our Test Lab for an in-depth look. We’ll cover our testing team’s conclusions and go over the design of the Helix Plus as well as its sizing, pricing, and performance ratings we awarded the mattress after testing it.

Testing Team Takeaways
To test the Helix Plus Mattress, we had three people on our testing team each take the bed home with them for one week. Here are their initial observations.
Logan Foley

Side sleeper

Has too many dogs in bed
This mattress felt a bit too hard for me personally, but I can see why it appeals to people who want a sturdy and dependable bed.
Jeremy Klein

Side sleeper

Nightly melatonin user
Like Logan, I usually lean toward a mattress that has deeper contouring for my hips and shoulders. I did like the ability of the Helix Plus to stay cool and its stable edge support.

Sleeps with a weighted blanket
While it’s definitely on the firm side, the overall design of the Helix Plus Mattress is really effective at ensuring that the bed cushions the joints without caving in beneath you.

Side Sleepers
In our Test Lab, the Helix Plus was a hit with side sleepers weighing at least 130 pounds, especially those over 230 pounds. Most of our side sleepers under 130 pounds thought the mattress felt too hard.
Side sleepers need the most cushioning of any sleeper type. When you sleep on your side, much of your weight rests on your hips and shoulders. This position can lead to uncomfortable pressure points when sleeping on a mattress that’s too firm.
The Helix Plus has the right firmness and overall performance to suit side sleepers with a higher body weight. Among those who weigh 230 pounds or less, side sleepers may find that the mattress lacks an optimal level of cushioning for their joints.
Back Sleepers
Like side sleepers, back sleepers need a balance of pressure relief and spinal support. However, back sleepers tend to prefer a firmer mattress that doesn’t compress too much beneath the midsection.
During our hands-on tests, the Helix Plus met these needs for most back sleepers. It was especially popular among back sleepers over 130 pounds who appreciated its sturdy feel and light cushioning to support the lumbar region.
Stomach Sleepers
The Helix Plus Mattress delivers firm support that our stomach sleepers weighing at least 130 pounds found exceptionally comfortable during our testing.
Stomach sleepers need the most support and lowest amount of contouring of any sleeper type. A mattress that’s too soft won’t hold its shape under the abdomen, causing the body to bend into an uncomfortable U shape.
The firm foam layers in the Helix Plus don’t allow stomach sleepers to sink into the mattress the way they might on a softer model. The pocketed coil core also helps keep stomach sleepers feeling as if they’re sleeping on instead of in their mattress.
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
“Since you don’t sink into the foams much, it’s easier for vibrations to move from one side of the mattress to the other.” – Logan
In our testing, one of the weaker points of the Helix Plus was its tendency to transfer motion across the mattress.
The coils and resilient materials generate a bounciness that makes it more likely to notice small vibrations when someone moves on the other side of the bed.
Based on the feedback from our testers, this shouldn’t be a huge concern for most people. But the Helix Plus may not be the optimal mattress for people who want to limit potential disruptions to their bed partner when they get in and out of bed.
Pressure Relief
7.5
/ 10
“There’s enough cushioning to prevent harsh impact against the surface of the mattress, but there’s less contouring than you’ll find on many other foam hybrids. That can be either good or bad depending on your preferences.” – Brad
Most of the pressure relief in the Helix Plus comes from the foam layers. The foam compresses under the heaviest parts of the body to help provide essential cushioning.
That said, the mattress has a firm (7) feel, which limits how much the foams conform to your pressure points. Ultimately, this reduces support for some people but increases it for others. In our testing, people over 230 pounds were most likely to value the pressure-relieving abilities of this mattress.
Temperature Control
8
/ 10
“I had no issues with the temperature of this mattress. I found that it slept cool, and the optional cooling cover is just icing on the cake.” – Jeremy
Our temperature control testing showed solidly above-average results for the Helix Plus. Since you don’t get hugged by the foam, there’s lots of space for air to move over your skin and resist heat buildup.
At the same time, air can flow through the pocketed coils, reducing heat buildup in the mattress. For hot sleepers, the optional cooling cover may be a worthwhile investment to get even better temperature regulation.
Edge Support
9
/ 10
“Everyone who tested this mattress noted that the edge support was a huge strength. The firmness level plus the reinforced perimeter really make the edge feel sturdy.” – Brad
Strong edge support is a standout characteristic of the Helix Plus. The support core of this mattress is lined with thicker coils to deliver more pushback around the edge. According to our testers, this extra reinforcement had a noticeable positive impact when they wanted to sit or sleep near the perimeter.
Ease of Movement
7
/ 10
“Given the firmness and minimal sinkage, I found that I could switch sleeping positions without much resistance.” – Jeremy
In our testing, most sleepers were able to move easily across the mattress. This is largely a function of the firm (7) feel and the fact that you don’t sag down into the foam layers. The pocketed coils also add a degree of bounce that enables easier movement.
Off-Gassing
7.5
/ 10
“There was a light but noticeable ‘new mattress smell” from the Helix Plus, but it was similar to what you’d expect from any foam hybrid.” – Logan
Almost all mattresses with foam materials give off an odor when they are first unpackaged, and the Helix Plus is no exception. Based on our testing, though, the smell is not too pungent and should fade away within a few days.
The smell comes from the off-gassing of tiny particles created during the manufacturing process. These trace chemicals are not considered harmful, and their odor will go away more quickly if you turn on a fan or open a window in your bedroom.
The Helix Plus Mattress is 11.5 inches tall. Our team rated it as firm, or a 7 on our 10-point firmness scale. This makes it firmer than most competing hybrid mattresses, which is a deliberate aspect of its design. The Helix Plus is built to support people with a higher body weight, giving them a supportive and durable mattress.
The cover of the Helix Plus is made with a knit fabric, but you can choose to upgrade to a GlacioTex cooling cover that uses special fibers to help dissipate heat. That optional cover also adds 2 inches of height to the mattress in the form of a quilted pillow-top.
The top layer is made with Helix’s Dynamic Foam, a type of adaptive polyfoam that reacts to the body’s weight to offer tailored cushioning. The next layer is a denser polyfoam that helps resist sagging and sinkage.
The support core of the mattress has two components. The top part is 8 inches of pocketed innerspring coils that are reinforced around the perimeter. These coils give the mattress its sturdy feel and strong edge support. Beneath the coils is a thin layer of high-density polyfoam that absorbs noise and enhances stability.
