The Helix Plus is a spring and foam hybrid mattress designed to give heavier sleepers proper support and pressure relief throughout the night. Because it was designed with plus size sleepers in mind, it should also last longer than a traditional mattress. A queen size currently retails for $1,190 but there are discounts available here to make it an even better deal. In keeping with Helix’s philosophy of custom comfort, they also offer the option to buy a cover that is cool to the touch helping you fall asleep just a little bit faster.

Overview and Ordering the Helix Plus

The Helis Plus is available exclusively through the Helix website. It comes with a standard 100-night trial where you can return it for a full refund within 100 nights of using it, that includes free shipping to you and free returns. It also has a 10-year warranty. This mattress comes shipped in a box like the one below. 

How do helix mattresses ship such a heavy mattress in a box this size? They use multimillion-dollar equipment to precisely package and vacuum seal these mattresses so they can be shipped without damage.

When you open the box, you will find a nice little manual about the mattress.

It doesn’t take long for this mattress to come to life. The spring system is engaged immediately and the top layers of foam will take a few hours to fully expand but if needed you could sleep on this mattress within 3 or 4 hours. It will take a full day for it to fully expand though.

Here’s a quick video explaining some of the features of the Plus.


Construction of the Helix Plus

Below are the construction details as listed on the Helix website.

Helix Nightfall Construction

Uniquely pressure relieving, we use Memory Plus Foam – a special Helix blend. Density: 4.0 PCF.

The bottom foam layer of the mattress provides base support and durability to the entire mattress.

My Helix Pus Findings

I have reviewed other mattresses for plus size sleepers including the Big fig and Winkbed Plus. In comparison to these, I found the Plus to be a bit softer. I weigh about 200 lbs. so I may not qualify for a heavy sleeper but in comparison to the other mattresses, this did feel softer.

The picture below shows how much sink you get with a 14 lb.s bowling ball.

Here’s another shot of sinkage towards the edge of the mattress. The coil system in this mattress uses a heavier gauge coil around the perimeter for better edge support so you can use the entire mattress and sleep right up to the edge.

Here’s a look at the inside of the mattress so you can see how each layer responds.


This mattress has a removable cover that could be washed or switched out for the cooling cover. The, “Ultra-Cool Cover” is an extra $125.nightfall cover

Helix Nightfall vs Winkbed Plus

Both the Helix Nightfall and Winkbed Plus are designed for heavy sleepers but there are some distinct differences. The Winkbed Plus is made with foam, spring and latex while the Helix Nightfall is made with Springs and foam. 

The Helix Nightfall is considerably softer than the Winkbed Plus and so is not ideal for stomach sleepers. Stomach sleepers should instead take a look at the Winkbed Plus. 

There are more foam layers at the top of The Helix Nightfall than the Winkbed Plus but the Winkbed Plus has quilted foam in the cover to give it a pillow top feel. 

The Helix Nightfall weight limit is 1,000 lbs. while the Winkbed Plus weight limit is 900 lbs so advantage Helix Plus. Compare this to the Big Fig weight limit which is 1,100 lbs. but is also the firmest of the three mattresses for heavy people. 

The Helix Nightfall, Big Fig and Winkbed Plus are the best hybrid mattresses for heavy people due to their high density foam layers, heavy duty coils.

My Helix Plus Recommendation

If you are a heavier sleeper and are frustrated with the lack of options out there, the Helix Plus is a welcome addition. It provides a softer feel with great pressure relief without sacrificing durability. The construction is well thought out in that the coil system provides great cradling of your body. The ultra-dense foams will hold up well over time and won’t feel too firm because of the cushioning you get from the coils.

Overall if you are a heavy sleeper, over 250 lbs. and looking for a softer cozier mattress that is breathable and still offers great support, the Helix Plus an excellent choice.

Helix PLUS Mattress: Pros and Cons


1. Designed for Support: The Helix PLUS mattress is built specifically to cater to plus-sized sleepers or those who prefer a firmer feel. Its reinforced support system, including the layer of XL wrapped coils and high-density memory foam, provides excellent contouring and weight distribution.

2. High Durability: Thanks to its robust construction, including a layer of DuraDense foam, the Helix PLUS mattress has a reputation for long-lasting performance. It’s designed to resist sagging and maintain its shape over time.

3. Excellent Edge Support: The Helix PLUS provides superior edge support compared to many other mattresses, thanks to the reinforced perimeters in the coil layer. This feature is especially beneficial for people who often sit on the edge of the bed or sleep near the edge.

4. Cooling Properties: With its breathable Tencel cover and open-coil design promoting airflow, the Helix PLUS mattress can help maintain a cool sleep environment, an asset for those who tend to sleep hot.

5. Trial Period and Warranty: Helix offers a 100-night sleep trial and a 15-year warranty, allowing customers to test the mattress and have long-term peace of mind about their purchase.


1. Potentially Too Firm for Some: While many appreciate the support offered by the Helix PLUS, it may be too firm for some sleepers, particularly those who prefer a plush, soft feel or lightweight individuals who might not compress the mattress enough to benefit from its conforming properties.

2. Motion Isolation: Although the Helix PLUS does a decent job at limiting motion transfer due to its hybrid construction, all-foam mattresses generally perform better in this aspect. This could be a minor drawback for light sleepers who share the bed.

3. Limited In-Store Availability: Helix primarily sells online, which means customers usually can’t try the mattress in a store before buying.

4. Initial Off-Gassing: Like many bed-in-a-box mattresses, the Helix PLUS may emit a slight off-gassing odor when first unboxed. However, this smell is non-toxic and typically dissipates within a few days.
