Construction
The Helix Plus mattress is 11.5 inches high. Designed to support heavier or big and tall sleepers, it has a combined weight limit of 1,000 pounds or 500 pounds for one sleeper. The foam and coil layers of this hybrid mattress combine to provide support, contouring and temperature control. The following sections describe the construction in detail.
Firmness
On a firmness scale of 1 to 10, the Helix Plus has a medium firm rating of 6 to 7. This firmness level ensures support for the plus-size sleeper without sacrificing comfort. It helps keep the spine properly aligned as it relieves pressure on neck, shoulders and hips.
Choice of Cooling Cover
Temperature control is a key factor for getting a good night sleep. With the Helix Plus mattress, you have two options for a cooling cover layer.
- TENCEL fabric — a breathable layer of fabric made from eucalyptus tree fibers. This cover choice offers moisture wicking and a soft texture to keep you cool and comfortable.
- GlacioTex cover and pillow top — cool to the touch, this cover is made from fibers that draw heat away from the body. The pillow top adds an extra level of comfort.
Ultra Dense Helix Dynamic Foam Comfort Layer
For pressure relief, the next layer is made of ultra-dense memory foam. Helix Dynamic Foam gives the mattress a medium firm feel and slight cushioning at the surface.
Transition Layer
The higher density Helix responsive Foam layer offers heavier sleepers a balance between support and contouring. This dense latex-alternative foam layer conforms to your body shape without letting you sink. It reinforces the medium-firm feel as it helps keep your spine properly aligned.

Extra Large TitanCore Coils
Inside the mattress core, 8 inch steel coils support and cushion plus-size sleepers. This support extends out to the edges of the mattress, where reinforced coils prevent sagging. You’ll love the bounce from the coil layer, which cradles your body while still offering ample support. The individually wrapped coils also provide motion isolation and permit airflow for additional cooling.
DuraDense Bottom Layer
The bottom layer of the Helix Plus mattress is made of DuraDense foam. This extra dense foam provides a final layer of durability and support to prevent impressions and sagging.

Helix Plus Mattress Review: Pros and Any Limitations
The Helix Plus mattress offers a variety of features that are helpful for heavier sleepers. After our research, we believe it offers the following benefits and minor limitations.
Balance Between Cushioning and Support
With the Helix Plus, heavier sleepers enjoy a balance between support and cushioning. The medium-firm mattress has layers of the highest density foam for durability and support. The Helix Dynamic Foam combines with the coil core to cradle your body without sagging.
This construction can help your spine stay aligned and take pressure off your neck, shoulders and hips. With your spine in a neutral position, you can sleep comfortably and wake up without feeling stiff or sore.
Edge Support
Edge support is crucial for preventing sagging. The core layer of coils is reinforced at the perimeter to provide extra edge support. With this feature, you won’t feel like you’re sliding off the edge when you get out of bed. You’ll enjoy the same level of support in every area of the mattress.
Sleep Cool and Comfortably
Waking up too warm or sweaty can make it difficult to fall asleep again. Besides, it’s downright annoying. With the Helix Plus, you can have your choice of a cooling top layer. The TENCEL fabric layer feels soft and helps keep you dry. The GlacioTex cover and pillow top option feels cool to the touch and draws heat away from the body while adding an additional layer of comfort. Whichever layer you choose will keep you cool and comfortable.
100-Night Sleep Trial
It takes time to get used to a new mattress. The best way to make a decision about a top-rated mattress for heavy people is to literally sleep on it for a while. The 100-night sleep trial gives you plenty of time to try your new Helix Plus. You’ll have to keep it for a 30-day break-in period, but you can return it within 30 to 100 days after the delivery date. You don’t have to worry about being stuck with a mattress that’s not right for you.
Convenient Delivery in a Box
After you order your Helix Plus mattress, you don’t have to deal with scheduling delivery and installation. You can go to work, run errands and live your life, knowing that the mattress will be delivered to your home. However, you may want to use a dolly or have someone help you carry the box to your bedroom.
Decompression After Unboxing
Once you’ve taken your Helix Plus out of the box and cut away the plastic wrap, you’ll have to wait a short time before you can use it. The mattress will need up to 45 minutes to decompress after you unroll it. You may also want to open the windows and let it air out to get rid of “off-gassing” odors that can occur with new mattresses.
Flexible Payment Options
It can be easier to make a purchasing decision when you can pay in installments. Thanks to monthly payment options through Affirm, Helix Plus may be more accessible. You can apply for the monthly payment plan at checkout.
Special Discounts
It’s nice to know that Helix recognizes the contributions of certain members of the community. The company offers discounts to veterans, military service members, military spouses and family members, first responders, teachers and students. Whether or not you are a member of any of these groups, you can feel good about purchasing from a company that offers this recognition.
