Which Mattresses Are We Comparing?

For this comparison, we’re looking at three popular Casper mattresses:

1. Casper Original
2. Casper Original Hybrid
3. Casper Wave Hybrid

From the Leesa lineup, we’re looking at the following:

1. Leesa Original
2. Leesa Legend
3. Leesa Sapira

The Casper Select, Casper Original, and The Casper were excluded due to their lower performance score and the 100% foam construction.

On average, these three mattresses scored 0.26 of a point lower than the Casper hybrid mattresses.

Leesa has a higher cooling score average of 9.66 compared to Casper’s average of 9.16. For the absolute best performance, opt for the Leesa Sapira, which had a perfect cooling score of 10 out of 10.

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 Wave Hybrid	9.0	77.8°	91.0°	-7.2°
Leesa Legend	9.5	81.2°	91.2°	-7.2°
Leesa Original	9.5	83.6°	92.1°	-5.6°
Leesa Sapira	10	81.2°	90.0°	-6.5°

• 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

The Casper Original Hybrid, Leesa Legend, and Leesa Original all have a score of 9.5.

Casper also includes other cooling benefits like a phase change cover on some mattresses as well as cooling bands or gel pods.

Leesa has many hybrid models that have excellent cooling with cooling covers or microcoils integrated into the comfort layer.

In our tests, mattresses in the “Chill” collection by Leesa scored 10 out of 10 for cooling (except for the Studio Chill which is their budget option that earned a score of 9.5 out of 10).

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.

Looking at sinkage, there is a wider range of sinkage on Casper mattresses than on Leesa mattresses.

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 Wave Hybrid	Deep	2.38″
Leesa Legend	Minimal	1.88″
Leesa Original	Moderate	2.09″
Leesa Sapira	Moderate	2.05″

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

The Casper Original has the least amount of sinkage of all mattresses in this guide with a bit of a floating feel.

The Casper Original Hybrid and Leesa Legend both have minimal sinkage between 1.88 – 1.91″.

The Leesa Original and Leesa Sapira have moderate sinkage between 2.05 – 2.09″.

The Casper Wave Hybrid has the deepest sinkage of 2.38″.

Looking at motion transfer, Leesa has lower levels and better performance than Casper. The motion transfer performance average of Leesa is 10 out of 10. By comparison, Casper mattresses had an average motion transfer score of 8.3.

Motion Transfer Test	Score	Acc. Range
Casper Original	8.4	11.30 m/s²
Casper Original Hybrid	8.5	10.87 m/s²
Casper Wave Hybrid	8.0	12.88 m/s²
Leesa Legend	10	4.38 m/s²
Leesa Original	10	2.06 m/s²
Leesa Sapira	10	4.66 m/s²

The average level of motion transfer across all mattresses tested to date is 8.48 m/s².

As you can see, motion transfer levels on Casper mattresses are significantly higher (avg. of 11.68 m/s²) than average. Motion transfer on the Leesa is well below average (avg. of 3.70 m/s²).

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

The Casper Wave Hybrid had the highest level of motion at 12.88 m/s² and the Leesa Original had the lowest levels at 2.06 m/s².

Moving along, let’s talk about material response time. Both Casper and Leesa had nearly perfect performance in terms of fast material response time.

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 Wave Hybrid	10	0.2 seconds	0.8 seconds
Leesa Legend	10	0.2 seconds	0.4 seconds
Leesa Original	10	0.3 seconds	0.5 seconds
Leesa Sapira	10	0.3 seconds	0.4 seconds

The average speed of material response time (based on all of our mattress tests to date) is 0.4 seconds to be mostly recovered and 0.8 seconds to be fully recovered.

All mattresses listed in this comparison had faster response time than average.

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

While bounce is a more preferential factor, Casper offers mattresses with moderate to high bounce while Leesa sticks to the extremes—either low, high, or very high.

If you’re looking for a more balanced level of bounce, Casper is the better pick, but for high or low levels, Leesa would perform better.

Bounce Test	Bounce Height	Bounce Range
Casper Original	Moderate	9.80″
Casper Original Hybrid	Moderate	8.21″
Casper Wave Hybrid	High	10.78″
Leesa Legend	High	11.57″
Leesa Original	Low	7.94″
Leesa Sapira	Very High	12.67″

The hybrid with the lowest amount of bounce is the Leesa Original at 7.94″ and the mattress with the highest level of bounce is the Leesa Sapira at 12.67″.

The average level of bounce is 9.62″, comparing all mattresses tested to date. The level of bounce for each mattress is documented in the videos below.

The average edge support is better on Casper (3.08″ avg.) than Leesa (5.75″ avg.).

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

Edge Support Test	Score	Max Sinkage	Lying Support
Casper Original	9.6	3.75″	Excellent
Casper Original Hybrid	10	2.25″	Excellent
Casper Wave Hybrid	9.9	3.25″	Very Good
Leesa Legend	8.8	5.50″	Excellent
Leesa Original	8.8	5.50″	Excellent
Leesa Sapira	8.4	6.25″	Excellent

For reference, the average level of sitting sinkage is 4.11″. In this comparison, all Casper mattresses perform better than average and all Leesa mattresses perform worse than average in this category.

That being said, Leesa does have other mattresses with good edge support—see the Leesa Legend Chill, Leesa Oasis Chill, Leesa Sapira Chill, Leesa Studio Chill, and Leesa Plus Hybrid all perform better than average.

Casper has an average sitting sinkage of 3.08″ and Leesa has an average sitting sinkage of 5.75″.

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

This part of our scoring looks at the expected sex performance based on several 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 Leesa 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 Wave Hybrid	9.9	10	9.9	10	10	9.0
Leesa Legend	9.6	10	8.8	9.0	9.5	9.5
Leesa Original	9.4	9.5	8.8	10	9.5	9.5
Leesa Sapira	9.6	10	8.4	9.0	10	10

Looking at this data, Casper had a slightly better average sex performance score of 9.80 while Leesa had a score of 9.53 out of 10.

The hybrid with the highest overall sex score was the Casper Wave Hybrid, which had a score of 9.9. The Leesa Original has the lowest level of sex performance with a score of 9.4.

What helps the Wave Hybrid, high bounce, and excellent edge support, are also the factors that hurt the Leesa Original, as it struggles in those areas.

Pressure relief is an important part of how a sleeper engages with a mattress. Comparing Casper and Leesa, we found both brands offer good levels of pressure relief, with most scores ranging between 9.5 and 10 (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 Wave Hybrid	10	5.0″	7.0″
Leesa Legend	9.5	4.5″	7.0″
Leesa Original	9.5	4.0″	6.0″
Leesa Sapira	10	4.0″	7.0″

The mattresses with the absolute highest scores include the Casper Wave Hybrid and the Leesa Sapira Hybrid.

The Casper Original and Casper Original Hybrid both have less comfort material than average (average is 4.19″).

Off-gassing is strong on both Casper and Leesa. However, when we consider the initial smell as well as the length of the off-gassing period, Leesa takes the win here.

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 Wave Hybrid	9.1	Strong	11 days
Leesa Legend	9.7	Strong	4 days
Leesa Original	9.8	Strong	3 days
Leesa Sapira	9.5	Strong	6 days

Casper mattresses take between 11-15 days to fully off-gas, compared to Leesa mattresses, which complete the off-gassing between 3-6 days.

For comparison, the average off-gassing period is 5 days so the Leesa Legend and Leesa Original are the only two mattresses that off-gas faster than average.

Both Casper and Leesa offer similar similar company policies, with matching trial periods, warranty lengths, and free shipping / returns.

Company	Casper	Leesa
Trial Period	100 nights	100 nights
Warranty	10 years	10 years
Shipping	$0	$0
Returns	$0	$0
Country of Origin	USA	USA

The average trial length is 165 nights. Both Casper and Leesa have a shorter trial than average, but still offer over 3 months to decide if the mattress is a good pick.

For most sleepers, this should be sufficient time for your body to adjust and love or hate the mattress.

Looking at warranties, both companies have 10-year warranties. Comparing this to averages, only 27% of the mattresses we’ve tested (over 190+ tested to date) have lifetime warranties. The average of the other 73% is 14 years.

Using this data, both Casper and Leesa also have shorter warranties than the average.

Looking at all available mattresses, Casper ranges in firmness from 4.5 to 6.5 out of 10 and Leesa mattresses range from 4 to 8 out of 10.

Of these two brands, Leesa has the greater firmness range. If you’re looking for something exclusively soft or firm, Leesa will likely be the better pick over Casper.

For a medium or medium-firm feel, both brands have solid options within that range.

For a soft mattress, the Leesa Oasis Chill, Leesa Sapira Chill, or Casper Nova Hybrid would be good options.

For a medium mattress, try the Casper Snow, Casper Wave Hybrid, Leesa Legend, or Leesa Legend Chill.

For a medium-firm feel, consider The Casper, Casper Original, Casper Original Hybrid, Casper Select, or any of the Leesa mattresses (excluding the Leesa Legend and Leesa Legend Chill).

For a firm feel, the only option is the firm version of the Leesa Sapira Chill.
