Helix vs. Casper
Most sleepers are combination sleepers which means that they change their sleeping positions many times throughout the night. If you are a combination sleeper as well, finding a mattress that can perfectly work for all your sleeping positions, especially if you share your bed with a partner can be a real challenge, but is not impossible with so many mattress choices available on today’s market.
In this Helix vs Casper review, we’ll be comparing two such mattress brands known for their ability to appeal to a wide range of sleepers with different sleeping styles. One is Helix, a completely customizable mattress, while the other is a new, updated universal comfort version of the Casper mattress that has gained a great popularity in the past several years.
Read our review and see which one may better suit your sleep preferences.
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.
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.
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.
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
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.
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.
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
• 10 Year Warranty
• Made in America
• Free Shipping
• Money back guarantee
The Helix mattress is priced at $900 for a Queen. This is a good price for customization and the quality materials and construction used in this mattress.
The “Split Mattress” configuration adds $100 to the price.

Construction and Materials
The Casper mattress is a 10″ all foam mattress made up of 4 layers:
- 1.5″ Top Comfort Layer – This layer is 1.5″ of open cell foam designed to provide cooling and comfort to the mattress.
- 1.5″ Response Layer – This layer is 1.5″ of responsive memory foam which provides bounce and responsiveness.
- 1.5″ Support Layer – This layer is 1.5″ of Zoned Support memory foam, which provides primary support and multi-regional zoned support to the areas of body where it is needed most including back, hips, and shoulders.
- 5.0″ Foundation Layer – This layer is 5″ of durable support foam that acts as the foundation and provides deep compression support.
The cover of the Casper mattress is made of a soft polyester blend. It is thick and snaps back into place quickly and won’t bunch up when you move around at night. It is removable as well so that it can be taken off and cleaned.
The exterior small dimples give the mattress a good feel and aid in breathability and increased airflow through its various layers.
Firmness and Support
While the Helix offers multiple customization options, the Casper comes in one universal firmness option designed to appeal to around 80% of sleepers, and we rate it at a 6.5 out of 10 (10 being the firmest).
Unlike the original Casper we reviewed that incorporated latex in its comfort layers, this one has a more supportive, faster response top comfort layer made of responsive foam.
The underlying comfort and support foam layers provide the body contouring and “sinking in” sensation that memory foam is normally known for, without being too soft and causing us to sink down too much and feel trapped in foam.
This mattress also provides enough support in the comfort layers without making Andrew sink all the way down through them and come to rest on the base and core support layers beneath as this updated version is also much denser and better made.
It does a great job of providing body hug and contour without causing you to feel trapped in foam, and it is supportive enough for all sleeping positions. It has enough give in the top comfort layer to support your shoulders and hips and enough firmness if you switch to your stomach and back.
As I have already mentioned, this mattress now includes Zoned Support which provides your body with optimal support in the areas where it is needed most such as your hips, back, and shoulders.
The new Casper mattress is much more comfortable than its predecessor which is largely due to the removal of the latex layer and including highest-quality foam layers.
The open cell foam used in the top comfort layer provides cooling and breathability and makes the mattress feel very comfortable for all types of sleepers.
The layer of responsive foam provides enough bounce and responsiveness needed when switching positions during the night and supporting your weight with ease, especially if you are a heavier sleeper like Andrew (230lbs) without causing too much motion transfer. All this makes this mattress excellent for sex as well.
The Casper has that classic memory foam body contouring and hug feel without causing the “sinking down into a hole” feel that traditional memory foam mattresses often tend to cause.
Although some review sites describe the Casper as being firm, we feel it is of perfect firmness with its responsive memory foam providing necessary bounce and responsiveness while cradling your body and creating that well-known feeling of hug typical for memory foam.
All in all, the new Casper is a comfortable, supportive and cool sleeping mattress that will provide you with a comfortable and sound sleep and the much-needed rest.
Being designed to sleep cool through advanced testing and molecular engineering, the Casper mattress, just like the Helix, does a great job at not sleeping hot. The open-cell foam used in the top comfort and cooling layer helps promote airflow throughout the night and prevent heat retention.
Casper even went so far as to have the thermal resistance tested by a third party lab, Element Materials Technology, and found it outperformed competitors.
As a couple living in Texas, we are very tough when it comes to beds that sleep hot and don’t do what they advertise, but the Casper does exactly what it says – it does not sleep hot at all.
The unique design and construction of this mattress prevents the buildup of heat and eliminates sweating during the night and the feeling of stickiness typical for most memory foam mattresses.
Sinkage and Motion Transfer
Although sinkage is largely weight dependent which means that heavier people will experience a larger degree of it than lighter people, the Casper does an excellent job at preventing excessive sinkage and preventing Andrew from bottoming out the mattress and rolling off its edges even though it is only 10″ thick.
Replacing the latex layer with foam did a great job at making the mattress responsive without causing excessive motion transfer, which makes it especially good for couples.
As mentioned, edge support is also great with this mattress, and better than in most all foam 10″ mattresses we have reviewed. The high-density foams used in its construction do a good job at providing even support throughout the mattress, including the edges and preventing us from rolling off them and Andrew from bottoming out the mattress.
Smell / Off-Gassing
The Casper mattress gets high marks in this category for not having too much of a noticeable smell upon opening the box which most memory foam mattresses tend to have due to their construction and their plastic packages.
With this mattress, there was markedly less off-gassing and odor which was rather surprising to us given its all foam construction.
- Engineered in-house at Casper Labs
- Designed and assembled in the USA
- Compatible with Casper sheets, pillow, duvet, foundation, and adjustable bed frame.
- 100 night Trial period
- 10 Year warranty
- Free Shipping
- 100% money back guarantee for Returns / Refunds
- Certi-Pur certified
The Casper mattress is very reasonably priced, coming in at $995 for a Queen, which is an excellent price given the quality of the materials used in the construction of this bed.

Which Mattress Is Right for You?
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.
Choose Casper mattress if you like:
- A supportive mattress – This mattress provides enough support in the comfort layers without making you compress through them, and it is suitable for all sleeping styles. It also includes Zoned Support which provides your body with optimal support in the areas where it is needed most such as your hips, back, and shoulders.
- Memory foam feel – The top comfort layer of the Casper mattress made of responsive memory foam creates that classic memory foam body contouring and hug feel without causing the feeling of being trapped in foam that traditional memory foam mattresses often tend to cause.
- A mattress that sleeps cool – The Casper mattress sleeps incredibly cool throughout the entire night. The open-cell foam used in the top comfort and cooling layer works together with a dimpled cover to promote airflow through the mattress, prevent heat retention, and create a cool and comfortable sleep surface necessary for a quality and sound night’s sleep.
