Which Mattresses Are We Comparing?

Casper offers a mix of hybrids and foam mattresses.

Below we are going to look at 3 popular Casper models for a deep dive comparison.

1. Casper Original (foam)
2. Casper Original Hybrid
3. Casper Snow Hybrid

From Saatva, we’ll be analyzing the following models.

1. Saatva Classic (coil-on-coil)
2. Saatva Latex Hybrid
3. Saatva Memory Foam Hybrid

The cooling performance average is slightly higher on Saatva mattresses (9.83) compared to the average on Casper mattresses (9.50). That being said, we see perfect 10 out of 10s from both brands.

The mattresses with the highest cooling performance is the Casper Snow Hybrid, Saatva Classic, and Saava Memory Foam Hybrid, all of which scored perfect 10 out of 10 scores.

Cooling Test	Score	Baseline	Max Temp	Ending Temp
Casper Original	9.0	64.2°	85.2°	-11.9°
Casper Original Hybrid	9.5	68.8°	86.5°	-11.5°
Casper Snow	10	79.5°	90.9°	-7.6°
Saatva Classic	10	81.4°	94.0°	-3.9°
Saatva Latex Hybrid	9.5	77.9°	91.0°	-8.4°
Saatva Memory Foam Hybrid	10	78.0°	89.4°	-8.1°

• 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 (after 5 minutes) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

Below, you can watch a video of how the heat dissipates on each mattress during our cooling test. For this test, we lie on the mattress for 15 minutes, get off the mattress, and then take periodic surface-level temperature measurements.

There’s no real consistency in brand sinkage between Casper and Saatva.

For reference, the average level of signage across all mattresses tested to date is 2.18″.

Sinkage Test	Sinkage Depth	Max Sinkage
Casper Original	Very Minimal	1.69″
Casper Original Hybrid	Minimal	1.91″
Casper Snow	Moderate	2.14″
Saatva Classic	Deep	2.40″
Saatva Latex Hybrid	Minimal	1.85″
Saatva Memory Foam Hybrid	Minimal	1.88″

All Casper mattresses have less sinkage than average with the Casper Original having the least amount of sinkage (1.69″).

By comparison, the Saatva Latex Hybrid and Saatva Memory Foam Hybrid also have less sinkage than average, but the Saatva Classic has more sinkage than average (2.40″).

Depending on what exactly you’re looking for, any of these mattresses could offer the level of hug and contour that you’re looking for.

The level of sinkage for each mattress is documented in the images below.

Looking at motion transfer, we saw better performance from Saatva compared to Casper. Saatva has a motion transfer average of 6.36 m/s², while Casper’s average was higher at 10.91 m/s².

Motion Transfer Test	Score	Acc. Range
Casper Original	8.4	11.30 m/s²
Casper Original Hybrid	8.5	10.87 m/s²
Casper Snow	8.6	10.55 m/s²
Saatva Classic	9.8	5.86 m/s²
Saatva Latex Hybrid	10	3.13 m/s²
Saatva Memory Foam Hybrid	8.7	10.11 m/s²

For reference, the average level of motion transfer across all mattresses tested to date is 8.34 m/s².

The Casper Original had the highest level of motion at 11.30 m/s² and the Saatva Latex Hybrid had the lowest levels at 3.13 m/s².

The level of motion transfer on each mattress is also documented in the videos below.

All Casper mattresses we’ve tested have more motion transfer than average and all Saatva mattresses have significantly less than average. For active couples or sleepers who wake easily, this could be a critical factor to consider.

Both Casper and Saatva have very fast material response times, regardless of the exact mattress or material type.

Response Test	Score	Mostly Recovered	Completely Recovered
Casper Original	10	0.2 seconds	0.7 seconds
Casper Original Hybrid	10	0.2 seconds	0.4 seconds
Casper Snow	9.9	0.6 seconds	1.2 seconds
Saatva Classic	10	0.4 seconds	0.8 seconds
Saatva Latex Hybrid	10	0.2 seconds	0.3 seconds
Saatva Memory Foam Hybrid	10	0.3 seconds	1.0 seconds

The average speed of material response time is 0.4 seconds to be mostly recovered and 0.8 seconds to be fully recovered.

All mattresses featured in this comparison were faster than average except for the Casper Snow, which was just slightly slower than average.

The level of responsiveness for each mattress is documented in the videos below.

Concerning bounce, Casper mattresses have moderate levels of bounce and Saatva mattresses have higher levels of bounce.

Bounce Test	Bounce Height	Bounce Range
Casper Original	Moderate	9.80″
Casper Original Hybrid	Moderate	8.21″
Casper Snow	Moderate	8.73″
Saatva Classic	Extremely High	14.67″
Saatva Latex Hybrid	High	10.82″
Saatva Memory Foam Hybrid	Extremely High	14.06″

The mattress with the lowest amount of bounce is the Casper Original Hybrid and the mattress with the highest amount of bounce is the Saatva Classic.

The average level of bounce is 9.61″, comparing all mattresses tested to date.

The Casper Original Hybrid and Casper Snow Hybrid both fall below that level. The Casper Original, and all Saatva mattresses listed are above the average bounce level.

The level of bounce for each mattress is documented in the videos below.

For lower levels of bounce, you may want to consider other all-foam mattresses by Casper. The Casper (6.53″) and Casper Select (6.93″) both have less bounce than the other Casper mattresses featured in this mash-up.

For the highest levels of bounce, opt for the Saatva Classic or Saatva Memory Foam Hybrid, both of which have significantly higher levels of bounce than average.

Edge support is slightly better on Saatva than Casper, but it’s a very close race. Casper mattresses have an edge support average score of 9.83 and Saatva mattresses have an average score of 9.93. Both brands offer highly supportive options for a range of mattress types.

Check out the table below to see how each mattress compares.

Edge Support Test	Score	Max Sinkage	Lying Support
Casper Original	9.6	3.75″	Excellent
Casper Original Hybrid	10	2.25″	Excellent
Casper Snow	9.9	3.25″	Excellent
Saatva Classic	10	3.00″	Exceptional
Saatva Latex Hybrid	10	3.00″	Exceptional
Saatva Memory Foam Hybrid	9.8	3.50″	Exceptional

The average score for edge support is 9.4, with a max sitting sinkage of 4.14″.

All Casper and Saatva mattresses featured in this comparison scored above average for this category with less edge sinkage than average when seated directly at the edge of the mattress.

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

This part of our scoring looks at the expected sex performance based on a number of performance factors.

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 and from these factors, we can generate a sex score for each mattress.

The table below shows how sex performance varies between Casper and Saatva mattresses.

Sex Test	Sex Score	Bounce	Edge Support	Noise	Pressure Relief	Cooling
Casper Original	9.8	10	9.6	10	9.0	9.0
Casper Original Hybrid	9.7	9.6	10	10	9.5	9.5
Casper Snow	9.8	9.7	9.9	10	9.5	10
Saatva Classic	9.9	10	10	9.0	10	10
Saatva Latex Hybrid	10	10	10	10	9.5	9.5
Saatva Memory Foam Hybrid	9.8	10	9.8	9.0	9.5	10

Looking at this data, we can see that all mattresses tested within this comparison perform better than average regarding sex.

For the absolute best performance, you can’t beat the Saatva Latex Hybrid mattress, which earned a 10 out of 10. This mattress has high levels of bounce paired with exceptional edge support as well. These two factors alone make up 80% of the sex score.

Pressure relief is an important part of how a sleeper engages with a mattress. Comparing Casper and Saatva, we found both brands to have good performance in this area, but technically Saatva is the better performer.

The pressure relief average for Casper is 9.33 and the Saatva average is 9.66 out of 10.

Pressure Relief Test	Score	Comfort Layer	Support Layer
Casper Original	9.0	3.5″	7.0″
Casper Original Hybrid	9.5	3.5″	7.0″
Casper Snow	9.5	3.0″	9.0″
Saatva Classic	10	4.5″	7.0″
Saatva Latex Hybrid	9.5	4.0″	8.0″
Saatva Memory Foam Hybrid	9.5	2.5″	9.0″

Again, we do see one outlier, the Casper Original, which only has a pressure relief score of 9.0 despite having the same thickness of comfort materials as many other mattresses featured here.

The Saatva Classic scored a perfect 10 out of 10 for pressure relief.

For comparison, the average level of comfort material across all mattresses tested to date is 4.19″.

The Saatva Classic is the only mattress that offers more comfort material than average, but the other mattresses still maintained good scores in this category.

Off-gassing is strong on Casper mattresses, and non-existent on Saatva mattresses.

Off-Gassing Test	Score	Initial Smell	Off-Gassing Period
Casper Original	8.8	Strong	15 days
Casper Original Hybrid	8.8	Strong	15 days
Casper Snow	9.4	Strong	7 days
Saatva Classic	10	None	0 days
Saatva Latex Hybrid	10	None	0 days
Saatva Memory Foam Hybrid	10	None	0 days

The big difference-maker here is that Saatva mattresses are shipped uncompressed. Casper mattresses are compressed and vacuum-rolled before shipping.

During the shipping process, gases from the mattress can build up and take a little time to fully dissipate once you unbox the mattress at its final destination.

The average off-gassing period is 5 days. Casper mattresses take between 7 – 15 days to fully off-gas.

If you’re sensitive to strong odors, Saatva would certainly be the best choice in this category.

Saatva has a longer trial and longer warranty than Casper.

Company	Casper	Saatva
Trial Period	100 nights	365 nights
Warranty	10 years	Lifetime
Shipping	$0	$0
Returns	$0	$99
Country of Origin	USA	USA

For comparison, the average trial length is 165 nights. Regarding the warranty, only 27% of the mattresses we’ve tested (over 192+ tested to date) have lifetime warranties. The average of the other 73% is 14 years.

Again, this gives Saatva the advantage for this category as well.

Looking at all available mattresses, Casper ranges in firmness from 4.5 to 6.5 out of 10 (if we include all available Casper models). Saatva mattresses range from 4 to 8 out of 10.

Saatva RX	6	Medium-Firm	Read Review

Considering support, both Casper and Saatva make supportive mattresses. They use high-quality materials, offering a variety of supportive mattress types with varying feels.

If you’re looking for something softer, the Casper Nova Hybrid or the Saatva Classic (soft) would be the best options to achieve that softer feel. These mattresses would be good picks for lightweight sleepers or those who sleep on their side and enjoy a bit more contour.

Both brands offer a wide range of options within the medium to medium firm feel including the Casper, Casper Original, Casper Original Hybrid, Casper Snow, and Casper Wave Hybrid. From Saatva we have the Saatva Classic (luxury firm), Saatva Memory Foam Hybrid, and Saatva RX.

For a slightly firmer feel, the Casper Select or Saatva Latex Hybrid may be solid options, both of which have a firmness of 6.5 out of 10. Either of these picks would be good for moderate-weighted sleepers who prefer to sleep on their back or stomach.

The Saatva Classic (firm version) is the sole mattress from either brand with a firm 8 out of 10 firmness (where 10 is the most firm). It’s best for back and stomach sleepers, but not side sleepers.

Heavyweight sleepers could also consider the Saatva HD, a mattress specifically designed for sleepers over 300 lbs.
