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	Excellent
Sinkage	Minimal
Motion Transfer	Moderate
Response Time	Extremely Fast
Bounce	Moderate
Edge Support	Exceptional
Sex	Excellent
Pressure Relief	Excellent
Off-Gassing	Good
Company	Excellent

How is the Casper Original Hybrid Different?

The Casper Original Hybrid has better overall performance than average and a price that is slightly above average as well—10% more than the average hybrid.

Advantages

Other advantages to the Casper Original Hybrid include slightly better cooling performance, fast material response time, better edge support than average, and slightly better sex performance as well.

Neutral Factors

This mattress has 22% less sinkage than average as well as 15% less bounce than average. Both sinkage and bounce are more preferential factors than anything else, but still important factors depending on the feel you’re looking for.

Disadvantages

Disadvantages include higher levels of motion transfer, better edge support than average, and a longer off-gassing period.

This mattress also has a thinner overall profile—only 10.5″ thick where the average is 12″ thick. This can negatively affect pressure relief for heavier sleepers or those who sleep on their back or stomach.

Cooling performance on the Casper Original Hybrid is excellent. During our tests, I felt no significant level of heat build-up. The mattress does a nice job of creating plenty of breathability and airflow.

The Original Hybrid has a relatively thin comfort layer at 3.5” thick. While less than great for pressure relief, it is beneficial for cooling performance.

A thinner foam layer represents less material that heat could be absorbed into.

• 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

In addition, the hybrid design creates ample airflow for the mattress at large while the thin non-upholstered cover helps air flow in and out of the top layers.

If we look at our objective data we can see a maximum surface level temperature of 86.5°. From minutes 0 to 1 we saw a temperature decline of 6.4°.

From minutes 0 to 5 we saw an 11.5 temperature decline. Overall, I’m pleased with the cooling performance.

Heat Dissipation Over Time

The Casper Original Hybrid had a minimal level of sinkage. In our tests we measured a pressure point sinkage depth of 1.91”. This is 0.29” less than the average of 2.20”.

The level of sinkage is documented in the image below.

Notably, my butt and midsection sank deeper, whereas my back, shoulders, legs, and arms had far less sinkage.

It’s not quite a floating feeling for the lighter parts of my body, but it certainly leans more in that direction.

Overall, I would describe the feel as fairly balanced, with a leaning towards floating on “top” of the mattress, as opposed to lying “in” the mattress.

The Casper Original Hybrid uses a poly foam comfort layer on top of memory foam in the core. These foams, combined with the pocketed coils, create a more traditional, balanced, and restrained body contouring hug around sleepers.

The Casper Original Hybrid has a moderate level of motion transfer. In our tests, we measured 10.87 m/s² of acceleration range. This is 3.05” more motion than the average of 7.82 m/s².

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

As a mattress type, hybrid mattresses tend to have more motion transfer relative to all foam mattresses, so this level of motion is not unsurprising.

Looking at our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.15 seconds. Motion drops off from 0.15 to 0.65 seconds, after which it returns to near-zero levels.

While the motion peaks are higher on the Casper Original Hybrid, the total motion duration is quite restrained. By 0.15 seconds the vast majority of all motion energy is dispersed. While less motion is always better than more, I don’t expect most sleepers will be overly bothered by the level of motion on the mattress.

The Casper Original Hybrid has an extremely fast response time. In our tests, we measured a mostly recovered response time of 0.2 seconds and a fully recovered response time of 0.4 seconds.

Both of these measurements are notably faster than the average. Based on all of our tests to date, we have measured an average mostly recovered response time of 0.45 seconds and an average fully recovered response time of 0.89 seconds.

The level of responsiveness is documented in the video below.

A faster response improves ease of movement, prevents a “stuck” feeling, and enhances sex. The Casper Original Hybrid responds nearly at the same speed as natural latex and other highly responsive poly foams. No complaints from me regarding responsiveness. 

The Casper Original Hybrid has a moderate level of bounce. In our tests, we measured a total bounce height of 8.21”. This is 1.41” less bounce than the average of 9.62”.

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

Ideally, I like to see 8-12” of total bounce height. It’s enough to realize the associated benefits of more bounce (ease of movement and sex), without being so high as to create significant issues (increase motion and trampoline feel).

At 8.21” the Casper is on the low end of my ideal range, however, it’s still within said range. I don’t expect most sleepers will find the level of bounce too high or too low.

The Casper Original Hybrid has exceptionally good sitting edge support and excellent lying edge support. In our sitting edge support tests, we measured just 2.25” of total sitting sinkage.

This is among the very best we’ve tested to date. On average we see 4.32” of sitting sinkage compression, making Casper’s Original Hybrid 2.07” better.

The Casper uses a 3.5” perimeter edge support foam, which is a significant contributing factor in overall edge support performance.

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

Lying edge support, while not quite to the level of sitting edge support, was still excellent. I felt well-supported in all sleeping positions.

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

As with sitting edge support, the 3.5” perimeter foam greatly enhances lying edge support. Overall, I’m extremely pleased with edge support performance.

Our sex rating formula looks at 5 different factors weighted based on their importance.

All factors are not equal in terms of significance, but each plays an important role.

Three of the most important factors are listed below with the associated testing scores:

In addition to the factors above, there are two other we consider as well, including pressure relief and cooling.

Here’s a look at the breakdown of how these 3 factors rank within the full formula:

We use the scores from all factors, plugged into the formula above, to derive a sex score for each mattress.

Sex Factor	Factor Weight	Score
Bounce	60%	9.6
Edge Support	20%	10
Noise	10%	10
Pressure Relief	5%	9.5
Cooling	5%	9.5

For the Casper Original Hybrid, these individual factors generated a sex score of 9.7.

This mattress has moderate levels of bounce (8.21″) and excellent edge support. These two factors alone are worth 80% of the sex score. Other factors, including noise, pressure relief, and cooling also had good performance scores.

Overall, this mattress would be great for sex and shouldn’t hinder the experience in any way.

Pressure relief on the Casper Original Hybrid is excellent. During our tests, I felt no significant building pressure points on my body.

The mattress does a nice job of alleviating pressure and keeping sleepers comfortable. My only concern is the relatively thin 3.5” comfort layer.

When it comes to the comfort layer, thicker is generally better. Ideally, I like to see 4” or more of comfort material. A thicker comfort layer is especially important for heavier-weighted sleepers, in addition to side sleepers.

With only 3.5” of material, heavier weighted sleepers and heavier sections of the body are more likely to sink through the comfort material and into the support coils.

The Casper does a good job of resisting pressure. Even so, some heavier-weighted sleepers may find it’s an issue.

Off-gassing on the Casper Original Hybrid is a little stronger than I would expect for a hybrid.

Right out of the box, the Casper Hybrid has a strong smell, which is not that uncommon. After unboxing, the mattress took 15 days to fully off-gas and be odor-free within the room.

This is a longer off-gassing period than the average of 3.68 days. While off-gassing does not generally affect the mattress long-term, it can lengthen the window of time that you are waiting before sleeping on the mattress.

As a company, Casper has generally good terms on their mattresses. They offer a 100-night trial period with a 30-night adjustment period. Both shipping and returns are free.

Company Factor
Trial Period	100 nights
Warranty	10 years
Shipping	Free
Returns	Free
Country of Origin	USA

If you keep the mattress, the Casper Hybrid also comes with a 10-year warranty, which protects from most manufacturing flaws as the mattress ages.

The Casper Original Hybrid has a medium-firm feel or 6 out of 10 on the firmness scale. This firmness would be suitable for a wide range of sleepers of various body weights and sleeping positions.

It is soft enough that lightweight sleepers won’t feel excessive pushback from the firmness, while also being firm enough that heavier sleepers won’t engage too deeply with the support layer (which can create pressure relief issues).

Support on the Casper Original Hybrid is excellent. During our tests, I felt well-supported in all sleeping positions. The mattress uses a zoned poly foam in the core of the mattress.

The 2.0” poly foam layer is more supported in the middle of the mattress, helping to create a more neutral spinal alignment. Typically, you see zoned support in the coil unit, but it’s not unheard of for a foam layer to be zoned.

In my view, zoned coils are typically better than zoned foam. All that said, I was generally pleased with the level of support I experienced.

The table below displays sleeper profiles that would be best suited for the Casper Original Hybrid 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	Maybe	Maybe

I felt well supported and did not experience significant pressure point build-up. My only concern for support is for heavier-weighted sleepers, especially 300+ pounds. 3.5” of comfort material just likely won’t be enough for the heaviest bodies. 

Design

The design of the Casper Original Hybrid combines poly foam, memory foam, and pocketed coils to create a mattress with a medium-firm feel and somewhat low-profile thickness.

This mattress aims to hit that balanced sweet spot that appeals to a very wide range of sleepers, including a range of body weights as well as sleeping positions.

Materials

The Casper Original Hybrid is advertised as an 11″ thick mattress, but ours measured about 0.5″ shy of that mark.

Within the 10.5″ profile, we measured four layers that make up the Casper Original Hybrid. From top to bottom, these layers are:

• 1.5” poly foam
• 2.0” memory foam
• 6.0” pocketed coil
• 1.0” support foam

While we’re on the topic of material names, let’s also discuss some fine print. The law tag has it labeled as 100% poly foam with a spring coil unit. However, the website says the middle layer is memory foam.

Memory foam is generally labeled as viscoelastic polyurathane foam law tags. In any case, I am not sure why we’re seeing the discrepancy here.

In our tests of the Casper Original, which seemingly has an identical foam comfort layer, the law tag was labeled 71% polyurethane foam pad and 29% viscoelastic polyurethane foam pad.

The Cover

The cover of the Casper Original Hybrid is the same cover we’ve seen on both the Casper as well as the Casper Original foam mattress.

The Comfort Layer

The comfort layer of the Casper Original Hybrid is made up of two layers of foam. There is a top layer of perforated poly foam. The holes in this layer help the mattress to have a fast response time as well as great cooling.

Below the top layer is a secondary layer of foam. The second layer is a 2.0″ memory foam, which is designed to enhance pressure relief, deep compression, and overall comfort of the mattress.

The Support Layer

The support layer of the Casper Original Hybrid is a 6.0″ layer of pocketed coils with a 1.0″ layer of high-density support foam below.

At the edges of the mattress, there is a perimeter-wrapping foam that helps reinforced the edges as well as keep the coils contained.

This perimeter foam is 3.5″ thick and really helps provide great edge support (as our tests showed above).

Product Evolution

The Casper Original Hybrid was launched in 2019, as an off-shoot of the Casper Original all-foam mattress launched in 2014.

Since its launch in 2019, there have been no significant changes made to the material construction of the Casper Original Hybrid.
