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

Our tests are based on the medium-firm version of the Leesa Sapira Chill.

How is Leesa Sapira Chill Different?

The Leesa Sapira Chill mattress has higher performance than average, but also a price that is higher than average—32% more than the average hybrid (a difference of $445).

Advantages

The biggest advantages to the Sapira Chill include excellent cooling, fast material response time, excellent edge support, a thicker overall profile, and fantastic sex performance (thanks, in large part, to the higher levels of bounce mentioned below.)

Neutral Factors

This mattress has moderate-level sinkage that is on par with the wider average (based on all of our tests to date). Bounce levels are 8% higher than average. Both bounce and sinkage are within acceptable ranges and are considered “neutral” factors since each sleeper tends to have different preferences in these categories.

Disadvantages

Besides the higher price, other disadvantages for the Sapira Chill include 48% higher levels of motion transfer, strong off-gassing, and a shorter trial period than average.

The Leesa Sapira Chill has exceptionally good cooling performance. During our tests, I felt no significant level of heat retention around my body.

The mattress is equipped with a phase change cooling cover that creates a “cool to the touch” feel. This cooling feel helps to create a more consistently cool and comfortable top layer, despite the use of a 5.25” all-foam comfort layer.

• 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 to the cooling cover, we have a pocketed coil layer that creates plenty of airflow. Lastly, Leesa uses only poly foam instead of memory foam, further helping to reduce heat retention issues.

In our objective cooling tests, we measured a max surface level temperature of 91.6° F. After getting off the mattress the temperature declined by 6.1 degrees from minutes 0 to 1, which is 1.57° cooler than average.

Heat Dissipation Over Time

From minutes 0 to 5 that decline was 9.0°, which is 2.04° cooler than average. When we consider the complete picture of objective data, subjective experience, and material analysis, I’m confident most sleepers will find the cooling to be exceptionally good.

The Leesa Sapira Chill has a moderate level of sinkage. In our test, we measured a pressure point sinkage depth of 2.16”. This is 0.01” more sinkage than the average of 2.17”.

We have a fairly significant level of body contouring hug. I wouldn’t call it “dramatic” (as I often do with many memory foam and memory foam hybrids), but it certainly leans more in that direction.

The level of sinkage is documented in the image below.

The 5.25” all-foam comfort layer creates lots of contour for the body. In addition, the primary 1.5” comfort layer feels like many other modern memory foams we’ve tested.

As a result, you experience a modest degree of the memory foam hug. But I do mean modest. It is well balanced by the quilted cover and 2.0” of additional comfort foam layers within the core of the mattress.

The Leesa Sapira Chill has a high level of motion transfer. In our tests, we measured a total acceleration range 12.55 m/s². This is 48% more motion than the average of 8.45 m/s².

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

On the surface, the Sapira Chill has the material components that should create a more moderate level of motion. I was so surprised at the high motion we ran our motion transfer test twice to double-check the data.

Both tests reported high levels of motion. It’s possible that the quilted cover is creating much of the additional motion. The cover itself is densely packed with foam material.

In addition, the tufting pattern is deeper than many other mattresses. This combination returns energy more dramatically, which we also saw with our bounce test.

In our motion transfer chart, which visualizes our accelerometer data, we see the highest motion from 0 to 0.21 seconds. Motion starts dropping by 0.21 seconds, but it’s not until 1.06 seconds that we return to near-zero levels of energy.

Mattresses with the least motion are able to fully disperse all energy by 0.3 seconds. Needless to say, the Leesa Sapira Chill is far from that mark. This is by far the weakest performance aspect of the Sapira Chill.

The Leesa Sapira Chill has an extremely fast responsiveness. In our tests, we measured a mostly recovered response time of 0.3 seconds and a fully recovered response time of 1.0 seconds.

The mostly recovered response is 0.10 seconds faster than the average of 0.40 seconds. And the fully recovered response time is 0.16 seconds slower than the average of 0.84 seconds.

The level of responsiveness is documented in the video below.

The 1.5” poly foam layer (that feels like a modern memory foam) is the slowest layer to respond among all of the materials within the mattress. The other layers rebound back to shape effectively instantly.

That said, overall responsiveness is still fantastic. I don’t expect this will be an issue for most sleepers.

The Leesa Sapira Chill has a high level of bounce. In our tests, we measured a bounce height of 10.51”. This is 0.84” more bounce than the average of 9.67”.

In general, I like to see 8-12” of total bounce height. It’s a sweet spot that maximizes benefits including ease of movement, response, and sex, while minimizing negatives including motion transfer and trampoline feel.

At 10.51” the Sapira Chill is well within the ideal range. I expect most sleepers will find this level of bounce to be satisfactory. 

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

The Leesa Sapira Chill has exceptionally good edge support for sitting and excellent support for lying.

In our sitting edge support tests, we measured a sitting sinkage compression of 3.0”. This is 1.11” less sitting sinkage than the average of 4.11”. When it comes to sitting edge compression anything 4.0” or less is great and the Sapira Chill exceeded that benchmark with ease.

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

Even while sitting directly on the edge there is no material collapse and I feel well supported. Lying edge support is nearly as good. While lying directly on the edge of the mattress I felt well supported in all sleeping positions.

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

The combination of a total 14.0” mattress profile with 2 rows of reinforced edge support coils is having a significant positive impact on overall edge performance.

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%	10	High
Edge Support	20%	10	Exceptional
Noise	10%	10	Minimal
Pressure Relief	5%	10	Exceptional
Cooling	5%	10	Exceptional

For the Sapira Chill, these individual factors generated a sex score of 10 out of 10.

The high level of bounce combined with the exceptional edge support make up 80% of the sex score.

Across the board, this mattress earns perfect 10s in every sub-category we consider when looking at sex.

Although high bounce can be a disadvantage for motion, for sex it’s a major boon.

The Leesa Sapira Chill has exceptionally good pressure relief. During our tests, I did not feel any significant level of pressure point build-up.

The mattress uses a thick 5.25” comfort layer. This is over a full inch more than the average comfort layer thickness of 4.2” (based on all of our tests to date). A thicker comfort layer doesn’t always mean better pressure relief, but in most cases it does.

The Sapira Chill uses high-quality foams at every level, which have a positive impact on the overall comfort dynamic.

When you combine the 5.25” comfort layer with the thick 8.0” coil unit and 0.75” support foam we have more than enough high-performance materials to create ample pressure relief. I expect most sleepers will find the level of pressure relief to be more than sufficient. 

Off-gassing on the Leesa Sapira Chill is strong out of the box and takes 10 days for the odor to fully dissipate.

We have tested over 180+ mattresses to date and the average off-gassing period is 5 days. This puts the Sapira Chill at 2X the average in terms of off-gassing days required.

The odor itself smelled like wet paint and was pretty offensive initially.

If you’re sensitive to strong odors, this may be more of an issue, but for most sleepers, it’s simply an annoyance that you need to wait for.

Once the mattress has fully off-gassed it shouldn’t be a long-term issue that affects any mattress.

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

Leesa offers a trial period of 100 nights, which is a bit shorter than the 164-night average for a trial period. It also comes with a 10-year warranty.

Of the 180+ mattresses we’ve tested to date, 27% have lifetime warranties. The average of the other 73% of mattresses is 14 years. Compared to this date, the Leesa warranty is shorter than average on all accounts.

Shipping and returns are both free from Leesa.

The Leesa Sapira Chill is available in 3 firmnesses including: plush, medium-firm, and firm.

Medium-Firm

We tested the medium-firm version, which has a firmness of 6 out of 10, where 10 is the most firm.

It has a medium-firm feel and would be generally suitable for a wide range of sleepers, including a range of body weights or sleeping positions.

Plush

We would estimate the plush version has a softness of 4 out of 10, where 10 is the most firm.

Firm

We would estimate the firm version has a firmness of 8 out of 10, where 10 is the most firm.

The Leesa Sapira Chill has excellent support. During our tests, I felt well-supported in all sleeping positions. The mattress checks all the support boxes I look for.

We have a robust 14.0” total profile with an 8.0” coil unit (1,032 coils) and 0.75” support foam foundation. In addition, this is a zoned coil unit. It includes 3 zones that create more support where you need it.

Based on all of our tests to date, the average total thickness is 11.9” with a 7.7” support layer. The Sapira Chill exceeds the average in both measurements.

The additional thickness helps create an improved overall support dynamic. Lastly, we have 2 rows of reinforced edge support coils along the perimeter.

These help improve support all the way to the very edge, which we found to be more than sufficient for both sitting and lying.

When we look at the material choices, layer design, and objective support data, I am confident most sleepers will find support to be more than satisfactory.

The Leesa is available in 3 different firmnesses. Each of the firmnesses has a slightly different set of sleeping positions and body types that they are best suited to.

Plush

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	Yes	Yes
150-250 lbs.	Maybe	Yes	Maybe
250-300 lbs.	No	Maybe	No

Medium-Firm

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

Firm

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	No	Yes
150-250 lbs.	Yes	Maybe	Yes
250-300 lbs.	Yes	Yes	Yes

Design

The Leesa Sapira Chill is a 14″ hybrid with a medium-firm feel (6 out of 10 on the firmness scale, where 10 is the most firm).

It includes a plush Euro-top cover, triple-layer comfort material, and a zoned support system. For a Leesa hybrid designed specifically for exceptional cooling, the Leesa Sapira is a great option.

Materials

The total thickness of the Leesa Sapira Chill is 14″ which is divided up into 6 layers. From top to bottom, these layers include:

• 1.75” Quilted cover
• 1.5” poly foam
• 1.0” poly foam
• 1.0” poly foam
• 8.0” pocketed coils
• 0.75” support foam

The Cover

The cover of the Leesa Sapira Chill is a plush quilted cover that is 1.75″ thick. Its exterior material makeup includes:

• 73% Polyester
• 25% Polyethylene
• 2% Spandex

It has a deeper tufted finish than other tufted mattresses we’ve tested. There is also a breathably gusset on the side for improved airflow.

Lastly, there are also two handles sewn into the sides of the mattress, which makes it easier to rotate or move the mattress as needed.

The Comfort Layer

The comfort layer is made of three layers of poly foam. The top-most 1.5″ poly foam feels like a modern memory foam. The other two foam layers are more typical responsive and transitional poly foams.

As the name suggests, transitional foams are important to help transition sleeper weight from the comfort layers into the support layers without a drastic difference in feel.

The Support Layer

The support layer itself contains up to 1,032 pocketed coils that are individually encased in fabric. These coils can move independently from one another and help improve support, and pressure relief, and also limit noise and motion transfer.

The coil system is divided into three distinct zones. Each zone is designed to target a different part of the body (ex: more supportive coils at the midsection and lighter coils at the head and foot of the mattress).

Along the perimeter, there are 2 rows of more supportive coils for reinforced edge support.

Product Evolution

The Chill collection of mattresses from Leesa was launched in October 2023, which includes the Studio Chill, Oasis Chill, Sapira Chill, and Deluxe Chill.

The Chill line is essentially an improvement to the original Leesa Studio, Sapira, and Legend mattresses. The most significant difference between the Chill and original versions is the addition of the cooling cover.

Most other basic design elements and material types are consistent between the Chill and original mattress types.
