Luxi vs. Helix

In continuation of our mattress face off series, today’s Luxi vs Helix comparison will be between the two unique customizable models.

These are not typical one-size- fits-all mattresses that can be found anywhere. They enable couples to have their own individual sides completely customized to their comfort needs or preferences.

With both of them made for the same purpose and dedicated to the same market segment, you may have a tough time choosing the right one to buy. We have tried out both of them and this is our review. Last updated Feb 17, 2019 @ 11:50 pm



Construction and Materials

The Luxi mattress is a 10″ thick memory foam mattress made up of 4 layers of latex, memory foam, support balancing technology, and support foam.

This mattress is unique in that it has “Flip-it / split-it” customization which means that each side of the mattress can be adjusted individually by unzipping the covering and re-configuring the layers. Besides this, the Luxi mattress combines many other unique innovations including a patent-pending Support Balancing Technology layer that enhances the softness and support within the layers.

Luxi Mattress Layers

It consists of the following layers:

  • 1.5″ Top comfort layer – This layer is made of 1.5″ of latex designed to provide cooling, comfort, and bounce to the mattress.
  • 1″ Middle support layer – This layer is made of 1″ of memory foam which minimizes motion transfer and provides responsive support and pressure relief.
  • 3.5″ Middle support layer – This layer is made of 3.5″ of proprietary Support Balancing Technology layer and is used to enhance the feel of memory foam and latex layers and support the body during sleep.
  • 3.5″ Bottom foundation layer – This layer is made of 3.5″ of base foam and provides the foundation for the layers above.

The Luxi has a 3/4″ quilted foam cover which makes a soft and durable outer layer that can be unzipped to configure the mattress.

The Luxi Support Balancing Technology layer is unique in that it provides cushioning comfort and conforming qualities of memory foam but with a responsive elasticity that rebounds quickly when the sleeper changes positions. It provides support similar to that offered by the pocketed coils and distributes body weight evenly across the mattress.

A layer of high-density open cell memory foam, enhanced with latex, and a breathable quilted organic cotton cover provides greater airflow, keeps the mattress cool, and offers an additional softness and better wear-life than most traditionally constructed memory foam mattresses.

Luxi individual side customization

We feel this is a great mattress for couples with different sleep preferences as it allows a good degree of customization so it can suit both sleepers and minimize motion transfer between them.

Firmness and Support

As we have already mentioned, the Luxi is a customized comfort mattress in that its SBT layers can be flipped upside down to put the softer SBT “knobbies” on top for a softer feel, or the bottom support layer for maximum firmness.

In the soft configuration (SBT layer on top), we would say that the Luxi is around a 4-5 out of 10 (10 being firmest.) The company did send us an additional soft comfort layer that we installed on top of this which made it a 5 layer mattress and placed it near 3-4 in terms of softness.

The default shipping configuration is around a 6 out of 10 (10 being firmest), with the latex/foam layer on top. The firmest option with the support layer on top puts the mattress around an 8 out of 10 in terms of firmness.

Support was consistently good with the Luxi, as the configurable design allows so many options depending on personal preferences of the sleepers. I configured my side to the medium firm while Andrew liked the soft, but both of us felt very good support being side sleepers.

The Support Balancing Technology does an excellent job of distributing our weight evenly during the night and supports Andrew’s heavier weight pretty well.


The Luxi is a very comfortable mattress, with the latex, memory foam, and support balancing technology construction providing a comfortable night sleep in all sleeping positions.

The ability to switch out sides makes it perfect for all sleepers from those preferring a softer feel to those wanting a firmer feel.
The soft cover makes a very nice sleeping surface that also includes padding in it which enhances comfort during the night.

Sleeping Hot

The Luxi sleeps quite cool due to the latex top layer, and the Support Balancing Technology layers and quilted cover that allow greater circulation of air through the mattress.

However, how cool this mattress will sleep depends on which layer you will put on top. The support foam layer tends to sleep less cool than other layers and may cause some heat retention.

Sinkage and Motion Transfer

As for sinkage, there was some sinkage on the softest comfort setting while the firm setting caused a minimal degree of it.

How good edge support in this mattress is depends on the side of the mattress and firmness setting again.

When it comes to motion transfer, we can freely say that it is non-existent with the Luxi mattress due to its split design. We tested it as a couple and did not feel each other moving during the night at all which makes this mattress one of the best mattresses for couples.

Smell / Off-Gassing

There was a minimal amount of off-gassing coming from the Luxi mattress upon opening the box, which is above average when compared to the other mattresses we have reviewed.

Construction and Materials

Helix is a 10″ hybrid mattress made up of latex, micro-coils, and foam. It consists of the custom configured layers to achieve the right degree of customization for your sleep preferences.

• 2″ Top Comfort Layer – This layer is 2″ of synthetic Dunlop latex designed to provide bounce, cooling, and responsiveness, and it can vary in firmness from ILD 15-32 (ILD being Indention Load Deflection, a measure of firmness) based on your answers from the questionnaire.
• 2″ Pressure Relief Layer – This layer is 1.5″ of micro coils that provide pressure, relief, bounce, and comfort, and create a similar feel to innerspring mattresses.
• 2″ Support Layer – This layer is 2″ of polyfoam that provides deep compression support and serves as the transitional support between the comfort and lower support layers. It also varies from ILD 20-26 based on the questionnaire answers.
• 4.5″ Foundation Layer – This layer is 4.5″ of high-density support foam that provides the overall foundation and support. It also ranges in ILD 26-33 based on the questionnaire.

Helix mattress internal layers

The cover of the Helix mattress is made up of 100% polyester, with a soft white top and lower blue bottom. The cover is thin and designed to assist in airflow and improve cooling.

Firmness and Support

With the Helix mattress, there is no pre-set level of firmness that can be evaluated based on pre-set factory construction of the mattress.
Instead, Helix customizes firmness and support for each sleeper according to their questionnaire answers and designs a mattress with different values for each side. Once the mattress is designed, they manufacture it and send it to your doorstep.

In our case, Andrew’s side required more support for his heavier weight (230lbs) and a softer feel which resulted in a mattress that felt around a 5 out of 10 on the firmness scale, with 10 being the firmest. Mattresses that are around 10″ thick usually tend to not be thick and supportive enough to handle my partner’s weight, but the Helix does a great job here due to the varying ILD of each layer in his side of the mattress. As for myself, I generally prefer a firmer mattress, and my side ended up being firmer without additional support for weight, and felt more of a 7 out of 10, with 10 being the firmest.

Helix mattress build specs


The combination of latex, micro coils, and foam with the soft breathable cover provides a necessary level of comfort on each side of the Helix mattress, while the hybrid design of latex and micro coils provides a good degree of bounce and responsiveness. As the Helix is essentially a latex and coil hybrid in the top layers, it provides more of a “sleeping on top of” feel vs. a “sleeping down in” feel typical for most full memory foam mattresses.

Sleeping Hot

The Helix mattress does an excellent job at minimizing heat buildup during the night due to the combination of latex and micro coils in its construction. The split design of the bed prevents the transfer of heat and helps in temperature regulation.

Sinkage and Motion Transfer

Just like the Luxi, the Helix mattress varies in terms of the amount of sinkage and motion transfer, depending on the construction of each side and weight of the sleepers.

Andrew’s side of the mattress customized to suit his weigh provides more support and less sinkage, while my side does the same for me, and I also don’t feel any significant sinkage.

Helix mattress profile

Edge support in this mattress is solid, but this again depends on the side of the mattress and gives varying results.

Motion transfer is good with the Helix as the blended mattress uses different material construction on each side depending on the individual preferences of the sleepers. Such construction of the mattress isolates the movement and prevents the shaking of the mattress when changing positions or getting in and out of bed during the night.

Smell / Off-Gassing

The Helix mattress that we reviewed gets high marks in this category for not having a noticeable smell upon opening the box. The hybrid latex and micro coil design (with roughly half the bed being constructed of foam) had some off-gassing but it largely dissipated over the first few nights.

Customer Service

Helix Sleep provides about the standard amount of customer service you can expect in a “Bed In A Box” online mattress retailer that includes:

• 100 Night Sleep Trial

Choose Luxi mattress if you like:

  • Adjustable mattresses – The Luxi mattress is unique in that it has “Flip-it / split-it” customization which means that each side of the mattress can be adjusted individually simply by unzipping the covering and re-configuring the layers.
  • Sharing your bed – This mattress could be a good pick for you if you plan on sharing your bed with a partner because of its split foam construction, which allows you to fully adjust each side of the bed to your and your partner’s specific sleep preferences.
  • Changing your sleep positions frequently – The Support Balancing Technology layer does an excellent job of supporting your weight in different sleep positions while providing enough pressure relief for a comfortable night’s sleep regardless of how much you toss and turn.

Choose Helix mattress if you like:

  •  A custom mattress – The Helix is made from foam / micro coil layers that can provide a wide range of feels and different levels of firmness. By adjusting the position of a certain foam, along with customization to density and ILD value, Helix is able to mix and match different types of mattresses within one design.
  • A split mattress – With the Helix, you can have two split mattresses sewn into one mattress. This is especially good for couples with different needs and body characteristics.
  • Sharing your bed – The Helix uses different material construction on each side depending on the individual preferences of the sleepers. Such construction of the mattress isolates the movement and prevents the shaking of the mattress when changing positions with your partner or getting in and out of bed during the night.
