At NapLab, we put each mattress to the test.

We test 10 different factors that impact the performance, comfort, and value of the mattress. Testing categories include:

Test	Rating
Cooling	Exceptional
Sinkage	Deep
Motion Transfer	Low
Response Time	Very Slow
Bounce	Moderate
Edge Support	Excellent
Sex	Excellent
Pressure Relief	Excellent
Off-Gassing	Poor
Company	Excellent

How is Casper Snow Hybrid Different?

The Casper Snow Hybrid has lower overall performance than the average mattress as well as a higher price. In most cases, this is the opposite of what we want to see from any mattress.

This mattress also has a distinct memory foam feel. You will need to love the feel of memory foam to be comfortable on this mattress.

Advantages

Specific advantages for the Snow Hybrid include exceptional cooling performance, lower levels of motion transfer, and better-than-average edge support.

Neutral Factors

This mattress has 9% deeper sinkage than the average mattress as well as slightly less bounce. Still, both bounce and sinkage remain at reasonable levels and should be non-issues for most sleepers looking for a balanced feel.

Disadvantages

The painfully slow material response time is a real setback for the Snow Hybrid. In our tests, this mattress took 7 times longer for the materials to respond compared to the average mattress.

The price may also be a disadvantage to many. In most cases, if you’re paying more, you want to get better performance. But with the Casper Snow we saw a 33% increase in cost and yet a decrease in performance.

At its current level, the Snow Hybrid scores in the bottom 20% of all memory foam hybrids tested to date.

The Casper Snow Hybrid has exceptionally good cooling. During our test, I felt no significant level of heat retention around my body.

• Baseline Temperature – the temperature of the mattress before anyone lies on it
• Maximum Temperature (0 minute) – the temperature of the mattress after lying on it for 15 minutes
• Ending Temperature (5 minute) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

The mattress is equipped with a phase change material cover and also has a phase change coating sprayed on the top layer of foam. This material creates a notable cooling feel when you first lie on the mattress.

In addition, the hybrid design, high-quality foams, and limited 3.0” comfort foam layer are all having a positive impact on the cooling. The mattress also uses what Casper calls their “heat delete bands”.

These are essentially thin sheets of an aluminum-foil-like material. While the idea is interesting, I am doubtful these bands are having any significant impact on cooling. Nevertheless, the mattress still creates fantastic cooling.

In our tests, we measured a max surface level temperature of 88.1°, which is 1.47° cooler than average.

After getting off the mattress, the temperature declined by 9.9° from minutes 0 to 5.

Heat Dissipation Over Time

Based on our objective tests, subjective experience, and material analysis, I expect most sleepers will find the Snow Hybrid is exceptionally cool.

The Casper Snow Hybrid has a deep level of sinkage. In our tests, we measured a pressure point sinkage depth of 2.36”. This is 0.20” deeper than the average of 2.16”.

The level of sinkage is documented in the image below.

The mattress has more of a classic memory foam feel. It creates a dramatic body contouring hug with a slow material response and excellent pressure relief.

In addition, the Snow Hybrid utilizes zoned foams with a firmer foam in the center and softer foam at the head and foot. For many sleepers, this helps to create a more neutral spinal alignment.

In order to feel comfortable on the Snow Hybrid you will absolutely need to love the feel of memory foam.

The Casper Snow Hybrid has a low level of motion transfer. In our tests, we measured a total acceleration range of 7.95 m/s². This is 7.7% less motion than the average of 8.61 m/s².

The level of motion transfer is also documented in the video below.

The more traditional memory foam type feel is helping to reduce much of the energy and motion on the mattress. Even with a fairly limited 3.0” comfort layer, the poly foam that is acting like memory foam soaks and disperses much of the energy.

In our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.15 seconds. Motion declines rapidly thereafter and by 0.97 seconds we return to near-zero levels of energy.

While the memory foam layer does no favors for response and ease of movement, it is a tremendous benefit to reducing motion transfer. I expect most sleepers will find this level of motion transfer more than low enough.

The Casper Snow Hybrid has a very slow level of material responsiveness. In our tests, we measured a mostly recovered response time of 2.8 seconds and a fully recovered response time of 5.1 seconds.

The mostly recovered time is 2.38 seconds slower than the average of 0.42 seconds. The fully recovered time is 4.21 seconds slower than the average of 0.89 seconds.

The memory foam-like poly foam within the mattress creates great pressure relief and body contouring. However, this foam is incredibly slow to recover back to its original shape.

The level of responsiveness is documented in the video below.

Based on all of our tests to date, the Casper Snow Hybrid has the 4th slowest material recovery (for the mostly recovered measurement; it’s 3rd slowest for the full material recovery).

I will note, the response time in the middle of the mattress is slightly faster since it uses a different kind of foam. That being said, one material in one spot on the mattress is not enough to compensate for the overarching slow feel to the Snow hybrid.

For reference, the video below shows the response time taken from materials directly in the middle of the mattress.

There is just no way to sugarcoat this factor. The Snow Hybrid has a very slow material responsiveness that will make it harder to move around on the mattress and may cause many sleepers to feel more “stuck” in the mattress. 

The Casper Snow Hybrid has a moderate level of bounce. In our tests, we measured a total bounce range of 9.54”. This is 0.16” less bounce than the average of 9.70”.

Ideally, I like to see bounce in the 8-12” range. At 9.54” the Snow Hybrid is within that sweet spot. Despite the memory foam-like poly foam comfort layer, the mattress still creates a surprisingly high level of bounce.

The level of bounce is also documented in the video below.

Certainly, the pocketed coil support layer is creating a majority of said bounce. While the bounce will help to improve sex performance and ease of movement, it probably isn’t enough of a difference maker to overcome the incredibly slow material response time, thereby creating more difficulty in moving around on the mattress. 

The Casper Snow Hybrid has excellent edge support for both sitting and lying. In our sitting edge support tests, we measured a sitting sinkage compression of 3.25”. This is 0.82” less sitting sinkage than the average of 4.07”.

Even when sitting directly on the edge of the mattress the Snow Hybrid retained its support and general shape. Lying edge support was equally as good.

The level of edge support while seated is documented in the images below.

The level of edge support while lying is documented in the images below.

I felt well supported in all sleeping positions even when lying directly on the edge of the mattress. The mattress uses a support foam that runs along the entire perimeter of the mattress.

This foam is 3.5” wide, 6.0” tall, and is having a sizable impact on edge support for both sitting and lying.

The Casper Snow Hybrid has excellent sex performance. Bounce and edge support are key to a strong dance without pants.

The Snow Hybrid has a 9.54” of bounce height and excellent edge support. These strong performance factors, combined with excellent pressure relief, minimal noise, and exceptionally good cooling, deliver fantastic performance overall. 

How Do We Determine Sex Score?

The best mattresses for sex have high bounce, good edge support, quiet materials, and good pressure relief and cooling.

These 5 factors make up the NapLab sex performance score.

Sex Factor	Factor Weight	Score	Rating
Bounce	60%	9.9	Moderate
Edge Support	20%	9.9	Excellent
Noise	10%	10	Minimal
Pressure Relief	5%	9.5	Excellent
Cooling	5%	10	Exceptional

For the Casper Snow, these individual factors generated a sex score of 9.9.

The Casper Snow Hybrid has excellent pressure relief. During our tests, I felt no significant level of pressure point build-up anywhere on my body.

I was surprised at the level of comfort on the mattress given the fairly limited 3.0” comfort layer. The Snow Hybrid uses just 3.0” of comfort foam. This is 1.2” thinner than the average 4.2” comfort layer thickness, based on all of our tests to date.

Nevertheless, the pressure relief was great. The foams all look and feel high quality. With just 3.0” there is still ample comfort. That said, as we discussed earlier, the mattress does have a notable memory foam feel.

This creates a more dramatic level of body contouring hug. So you’ll really need to prefer that type of feel to be comfortable.

Off-gassing on the Casper Snow Hybrid was strong right out of the box. The mattress notably smells like wet paint. It’s my best guess that this increase in smell is coming from the spray on phase change coating, as well as the memory foam-like poly foam.

The mattress smelled for 31 days, which is significantly longer than the average off-gassing period, which is 5.89 days. Needless to say, the strength of smell, smell like wet pet, and smell duration aren’t great. Sensitive noses will most likely want to avoid this mattress.

Casper’s company terms and conditions are pretty typical compared to what we see across the industry. They offer a 100-night trial period and a 10-year warranty on all of their mattresses.

Comparing all mattresses tested to date, the average trial length is 164 nights, so Casper’s trial is shorter than average. That being said, 100 nights should still be enough time for you to properly decide if you like the mattress or not.

How Do We Determine Company Score?

The company score takes a look at factors that may influence your experience with the mattress.

Factors include length of the trial period, warranty, shipping / return costs, and country of origin.

Company Factor	Factor Weight	Score	Data
Trial Period	25%	9.0	100 nights
Warranty	25%	10	10 years
Shipping	25%	10	$0
Returns	25%	10	$0
Country of Origin	0%		USA

For Casper, these individual terms and conditions generated a company score of 9.8.

The Casper Snow Hybrid has a medium feel with a firmness level of 5 out of 10. In the context of all mattresses, the most common firmness level is typically a 6.

At a firmness of 5, the Snow Hybrid is just a touch softer than many other mattresses on the market, but still firm enough to provide adequate support for a range of sleeper profiles.

The Casper Snow Hybrid has excellent support. During our tests, I felt well-supported in all sleeping positions. The mattress uses both a layer of foam and pocketed coils to create support.

A 6.0” layer of pocketed coils sits atop the 2.5” support foam foundational layer. This 8.5” of support materials is 0.7” thicker than the average support layer thickness of 7.8”.

Notably, the mattress has a medium feel, 5 out of 10 on our firmness scale, where 10 is the most firm. This feel is suitable for most body types and sleeping positions.

However, some heavier weighted bodies, especially heavier weighted back and stomach sleepers, may find that it creates a little too much sinkage and compression to create proper support.

For all others, I’m confident most will find the support to be sufficient.

Check out the table below to see the sleeper weights and sleeping positions that would be best suited for this mattress.

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	Yes	Yes
150-250 lbs.	Yes	Yes	Yes
250-300 lbs.	Maybe	Yes	Maybe

Design

The Casper Snow is an 11.5″ hybrid mattress with a medium feel. It is the only hybrid specifically designed for exceptional cooling within the Casper lineup.

If you’re looking for a medium feel, a phase change cover, and cooling technology within the layers, the Casper Snow may be a solid pick.

Materials

The Casper Snow Hybrid is made of a combination of foam and pocketed coils. It has a 3.0″ comfort layer and an 8.5″ support layer. From top to bottom, the layers include:

• 1.0” memory foam
• 2.0” memory foam
• 6.0” pocketed coil
• 2.5” support foam

The Cover

The cover of the Casper Snow Hybrid looks and feels very similar to the other covers used on the newly re-released Casper mattresses (see: Casper Dream Max).

It is a thin, knit blend that has good stretch and breathability. There is no tufting for added loft or contour, giving the mattress a modern feel and also likely improving cooling performance.

The Comfort Layer

The 3.0″ comfort layer is made of two different poly foam layers (that perform and feel like memory foam). On top, there is a 1.0″ foam layer that is sprayed with a phase change coating.

This second layer is a 2.0″ zoned poly foam, where the central part of the foam layer (the blue portion) has a more supportive feel than the parts supporting the head and feet.

This zoned approach helps maintain spinal alignment when lying on the mattress.

For added context, the Heat Delete bands (as mentioned in the cooling performance tests) are fused between the first and second foam layers of this mattress. The Snow Hybrid has a total of 3 bands and the Snow Max contains 6 bands.

The Support Layer

The support layer is made up of a 6.0″ pocketed coil system followed by a 2.5″ support foam base.

Along the perimeter of the mattress, there is an edge support foam, designed to improve rigidity when sitting or lying directly on the edge of the mattress.

Product Evolution

Casper originated in 2014 with its launch of the Casper all-foam mattress. In 2019, Casper hybrids were released and models continued to be added to their collection until 2023.

In early 2024, Casper discontinued their entire mattress line and launched 5 new mattress models.

Prior to this rework, there were 4 Casper hybrids:

• Casper Original Hybrid
• Casper Nova Hybrid
• Casper Wave Hybrid
• Casper Snow (still available; however it has a new design)

The original Casper Snow has been renamed to the Casper Snow Hybrid (however, both mattresses were hybrids). The layered design was similar between the two models, but the exact materials and performance (especially material response) is quite different.

Casper’s 2024 lineup includes:

• Casper One – all foam, most basic, least expensive
• Casper Dream – least expensive hybrid
• Casper Dream Max – higher performance hybrid
• Casper Snow – least expensive, cooler hybrid
• Casper Snow Max – higher performance, cooler hybrid
