Helix has been very successful with its personalized mattress. Customers have found the right mattress by taking a quiz regarding their sleep position, weight, and firmness preferences and then purchasing a mattress that is customized to these factors.

Now, Helix offers three special mattresses made to fit more specific sleeping needs. One of these mattresses is the Helix PLUS, which is designed to offer extra support for big and tall sleepers.

This review will cover everything people need to know about this mattress, including a full breakdown of the construction, the pros and cons, comfort, support, edge support, motion isolation, breathability, durability, and much more.

The Helix Plus is a supportive hybrid that could be a great match for heavier sleepers. 

Who Might Like The Helix PLUS …

  • Heavier people- If someone is larger and worry about support or a sagging mattress, this might be the mattress for them. It has durable materials that will fight body indentations, and the extra tall coils should keep people well supported.
  • Those who are looking for a long-lasting mattress- If someone needs a mattress that will last them for some time, the PLUS could work for them. Its high-density foams and coils will ensure this mattress lasts for a while.
  • Back or stomach sleepers who want extra support- While this mattress is made for heavier people, it could be a good fit for anyone who wants a mattress with extra support. If people sleep on their back and/or stomach, they shouldn’t have to worry about their hips sinking in too far on this mattress.

Who Might Not Like The Helix PLUS …

  • Lighter people- If someone is smaller than average, this mattress really isn’t made for them. It will probably be too firm for most smaller people. If someone is smaller, they should consider one of the other, softer models.
  • Side sleepers- Even if someone is a heavier person, this mattress may be a bit firm on their side. People may feel some pressure on their shoulders and hips. This mattress is quite firm, so they may want to look at a softer Helix model.
  • People who prefer a classic memory foam feel- If people like to sink into their mattress and sleep “in” it rather than “on,” this might not be the best choice. It has a balanced hybrid feel, so people sleep “on” the mattress.

Construction Overview

  • The mattress is 13” tall and features multiple foam and support coil layers.
  • The cover contains Tencel, a material known for its breathability and cooling properties.
  • The first layer is 1.5” of Helix Dynamic Foam, which is a latex-foam hybrid.
  • Next, there is a 1” layer of gel memory foam, which provides great pressure relief and body contouring.
  • After that, there is a 1.5” transition layer of Memory Foam Plus, which is an extra layer to help with contouring and support for heavier people.
  • Then there is an 8” layer of individually wrapped coils, which is highly supportive, breathable, and durable.
  • Finally, the base layer is 1” of Dura Dense foam, which the support coils can rest on.

Construction Takeaways

  • The foam layers are high-density, which should keep the mattress from sagging (as mattresses can often do with heavier people).
  • The coils are specifically designed to handle heavier weights. They are taller and can take more compression than typical coils, so they should give the extra support that heavier people need in their mattress.
  • The mattress is also designed to keep people cool while they sleep, as the cover is quite breathable, and the coils should allow for nice airflow.
  • The durable components should make this a longer-lasting mattress and a great overall investment. The high-density foams, coils, and durable base layer should give this mattress a long life.

The Helix Plus is a supportive hybrid that could be a great match for heavier sleepers. 


This mattress felt like a 7 out of 10 in terms of firmness, or a bit firmer than average. It has a relatively soft comfort layer, but when I press down, I engage the transition layer and coils fairly easily. On my back, I felt very nice support, as I felt the top foam layer pressing into my lumbar area, and my hips sunk in a bit, but not too much.

On my side, I did feel some pressure on my shoulders and hips. Again, I believe I was feeling those supportive layers beneath the comfort layers.

Moving to my stomach, I felt well supported ,as I did not feel my hips sinking in as they often do when I am on my stomach. It was a very nice match for me in this position.

In terms of feel, the mattress has a balanced hybrid feel where there is a bit of that responsive foam feel on top with the feeling of coils beneath.

Motion Transfer

During my tests, I did see some motion transfer, probably because of the use of coils in the construction. The glass was disturbed when I pressed into the mattress. Also, when I rolled near the glass, it was disturbed.

This was not surprising to me. While there is foam on top, it doesn’t allow you to sink in. All-foam mattresses are often better with motion transfer.

Overall, I think the motion transfer was below average on the Helix PLUS.

Edge Support

If someone is a larger person, they will also want to know if they can use the full surface area of the mattress, as edge support is very important.

This mattress actually reinforces the outer coils to make the edge more secure, and sitting down on the mattress, I don’t feel like I am going to fall off. Also, when I am lying down, I feel like I can lie fairly close to the edge without rolling off.

Overall, I felt the edge support was decent on this mattress.

What Makes This Mattress Stand Out?

  • It is supportive enough for heavier people- The taller coils and extra layers of high-density foam should ensure larger people get the support they need.
  • The mattress shouldn’t sag- Heavier people often make indentations in their mattresses over time, but the high-density foams used in this mattress are designed to prevent this sagging.
  • Overheating shouldn’t be an issue on this mattress- The cover is breathable, and the coils allow for good airflow, so people shouldn’t be getting hot on the Helix PLUS.
  • It should be a long-lasting mattress- Those same components that fight sagging should also ensure this mattress lasts for quite a few years.

Unboxing This Mattress

The Helix PLUS is a bed-in-a-box mattress, which means it will come compressed and be shipped straight to the shopper’s door.

People will want to begin by removing the rolled up PLUS mattress from its box. Then, preferably with another person’s assistance, they should position the roll on their bed.

Then they can carefully cut away the first layers of plastic until the still-compact mattress can be laid down flat. Then, they should pierce through the final layer of plastic and the Helix PLUS will expand. They can then simply clear away the excess plastic and allow their mattress to breathe and fully expand.


I think the Helix PLUS does a very good job of addressing the issues that heavier sleepers deal with. Lack of support and sagging are both addressed, and I feel very nice when I am on my back and stomach. Lighter people and many side sleepers may find this mattress to be too firm, however. There are many softer options in the Helix line.

The Helix PLUS comes with free shipping and returns, a 100-night sleep trial, and a 10-year warranty. There is also an optional cool cover for purchase as well as Helix pillows.

Consumers should take a look through this review multiple times, assess their own needs and preferences, and then ultimately make a more informed decision.
