Which Mattresses Are We Comparing?

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

1. Casper One
2. Casper Dream
3. Casper Snow

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

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

Leesa has a higher cooling average than Casper, but both brands offer at least one mattress that earns a 10/10 cooling score—the Casper Snow and the Leesa Sapira.

Cooling Test	Score	Baseline	Max Temp	Ending Temp
Casper Dream	9.0	75.0°	90.0°	79.7°
Casper One	8.0	73.1°	89.6°	79.7°
Casper Snow Hybrid	10	73.8°	88.1°	78.2°
Leesa Legend	9.0	81.2°	91.2°	84.0°
Leesa Original	9.0	83.6°	92.1°	86.5°
Leesa Sapira	10	81.2°	90.0°	83.5°

• 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

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.

Leesa has a sinakge that ranged from minimal to moderate sinkage. Casper has a wider range, including minimal sinkage and a mattress with deep sinkage (Casper Snow Hybrid).

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

Sinkage Test	Sinkage Feel	Sinkage Depth
Casper Dream	Minimal	1.89″
Casper One	Minimal	1.77″
Casper Snow Hybrid	Deep	2.36″
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.

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 8.23.

Motion Transfer Test	Score	Acc. Range
Casper Dream	8.0	9.48 m/s²
Casper One	8.0	9.42 m/s²
Casper Snow Hybrid	8.7	7.95 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 8.67 m/s².

As you can see, motion transfer levels on Casper mattresses are just slightly higher (avg. of 8.95 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 Dream had the highest level of motion at 9.48 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 fast material response time, but some mattresses were faster than others.

Response Test	Score	Mostly Recovered	Completely Recovered
Casper Dream	9.9	0.2 seconds	0.4 seconds
Casper One	9.9	0.2 seconds	0.4 seconds
Casper Snow Hybrid	5.0	2.8 seconds	5.1 seconds
Leesa Legend	9.9	0.2 seconds	0.4 seconds
Leesa Original	9.4	0.3 seconds	0.5 seconds
Leesa Sapira	9.5	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 except for the Casper Snow Hybrid.

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

While bounce is a more preferential factor, both brands offers a range of bounce levels

Casper includes a bounce range between moderate and high (8.77-10.73″) and the Leesa range is a bit wider—low to very high (7.94-12.67″).

If you’re specifically looking for very high bounce, the Leesa Legend or Leesa Sapira are great options.

Bounce Test	Bounce Feel	Bounce Height
Casper Dream	High	10.73″
Casper One	Moderate	8.77″
Casper Snow Hybrid	Moderate	9.54″
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 9.63″, 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 (3.58″ avg.) than Leesa (5.75″ avg.).

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

Edge Support Test	Score	Sitting Sinkage	Lying Support
Casper Dream	8.9	4.00″	Excellent
Casper One	8.2	3.50″	Fair
Casper Snow Hybrid	9.4	3.25″	Excellent
Leesa Legend	8.0	5.50″	Excellent
Leesa Original	8.0	5.50″	Excellent
Leesa Sapira	7.5	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 3.58″ 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 Dream	9.1	9.2	8.8	10	8.0	9.0
Casper One	8.3	8.0	9.4	10	6.0	8.0
Casper Snow Hybrid	8.9	8.5	9.7	10	9.0	10
Leesa Legend	9.0	9.7	6.9	8.0	9.0	9.0
Leesa Original	7.6	7.4	6.9	10	9.0	9.0
Leesa Sapira	9.1	10	5.9	8.0	10	10

Looking at this data, Casper had a slightly better average sex performance score of 8.76 while Leesa had a score of 8.56 out of 10.

The mattress with the highest overall sex score was a tie between the Casper Dream (9.1) and the Leesa Sapira. The Casper One has the lowest level of sex performance with a score of 8.3.

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 9.0 and 10 (out of 10).

The only outlier to this standard is the Casper One which had a nose-dive score of only 6 out of 10

Pressure Relief Test	Score	Comfort Layer	Support Layer
Casper Dream	8.0	3.0″	8.5″
Casper One	6.0	3.0″	7.0″
Casper Snow Hybrid	9.0	3.0″	8.5″
Leesa Legend	9.0	4.5″	7.0″
Leesa Original	9.0	4.0″	6.0″
Leesa Sapira	10	4.0″	7.0″

The mattress with the absolute highest score was the Leesa Sapira Hybrid.

The Casper Snow, Leesa Legend, and Leesa Original all had commendable scores of 9.0 out of 10, despite having varying thicknesses for the comfort layer.

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	Smell Duration
Casper Dream	7.8	Strong	8 days
Casper One	6.7	Strong	12 days
Casper Snow Hybrid	4.4	Strong	20 days
Leesa Legend	8.9	Strong	4 days
Leesa Original	9.2	Strong	3 days
Leesa Sapira	8.3	Strong	6 days

Casper mattresses take between 8-20 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
Score	8.5	9.5
Trial Period	100 nights	100 nights
Warranty	10 years	10 years
Shipping	$0	$0
Returns	$0	$0
Trust	Good	Outstanding
Country of Origin	USA	USA

The average trial length is 174 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 23% of the mattresses we’ve tested (over 220+ tested to date) have lifetime warranties. The average of the other 77% is 13 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 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.

Check the table below to see the details of each mattress.

Firmness	Rating	Feel
Casper Dream	6	Medium-Firm
Casper Dream Max	4.5	Soft
Casper One	6	Medium-Firm
Casper Snow Hybrid	5	Medium
Leesa Legend	5	Medium
Leesa Legend Chill	5	Medium
Leesa Natural Hybrid	6	Medium-Firm
Leesa Oasis Chill	4, 6	Soft, Medium-Firm
Leesa Original	6	Medium-Firm
Leesa Original Hybrid	6	Medium-Firm

Leesa Reserve	4, 5.5, 7	Soft, Medium, Slightly Firm
Leesa Sapira	6	Medium-Firm
Leesa Sapira Chill	4, 6, 8	Soft, Medium-Firm, Firm
Leesa Studio	6	Medium-Firm
Leesa Studio Chill	6	Medium-Firm

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

For a medium mattress, try the Leesa Legend or Leesa Legend Chill.

For a medium-firm feel, consider Casper One, Casper Dream, 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.
