How is Keetsa Supreme Different?

The Keetsa Supreme is a 12.25″ memory foam mattress with an overall performance level that is below average and a price that is above average. The result is a pricier mattress that has lower performance, not exactly the balance we like to see.

Advantages

Advantages of the Keetsa Supreme include exceptional pressure relief and faster-than-average off-gassing.

Despite being all memory foam, this mattress has surprisingly fast off-gassing.

Neutral Factors

The Keetsa has a deep level of sinkage and extremely low levels of bounce. Both bounce and sinkage are considered neutral factors since different sleepers will have different preferences in this area.

To enjoy this mattress, you will need to prefer a more encompassing feel as well as a more dramatic body contouring hug.

Additionally, the Keetsa Supreme has a motion transfer score that is very near average as well as a response time that is exactly average (8.7).

Given the dramatic contour and soft feel of this memory foam mattress, the average response time was actually a little better than expected.

Disadvantages

Disadvantages of the Keetsa include worse cooling performance than average, worse edge support, and a sex score that is significantly below average.

Lastly, if you decide to return the Keetsa Supreme, you’ll need to be prepared to pay a $169 return fee that will be deducted from your refund.

The Keetsa Supreme has good cooling. During our tests, I felt a slight to moderate level of heat retention around my body.

Fortunately, it was nothing I’d describe as “hot”, but it’s also clear the cooling performance doesn’t rise to the same level as many other mattresses we’ve tested.

That being said, a less-than-amazing cooling performance is typical for an all-foam memory foam mattress like this. Memory foam, by its nature, simply absorbs and retains more heat than many other types of foam, and that’s exactly what we measured here as well.

• 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

This mattress lacks many of the features that we see creating better cooling performance in other mattresses, including no phase change materials, no thermoreactive cooling fibers, no coils for improved airflow, and no cooling material infusions into foams.

In our objective temperature tests, we measured a max surface level temperature of 91.8° F. This is 1.5° warmer than the average of 90.3° F, based on all of our tests to date.

After getting off the mattress, the temperature declined by 5.1 degrees from minutes 0 to 1, which is 0.3 degrees cooler than the average 0 to 1 minute decline of 4.8 degrees.

When we consider the combination of objective data, my subjective experiences, and an analysis of the materials, I’m confident in my view that cooling is good.

The Keetsa Supreme has deep sinkage. During our tests, we measured a pressure point sinkage depth of 2.43″. This is 0.17″ more sinkage than the average sinkage depth of 2.26″, based on all of our tests to date.

The mattress creates a dramatic body contouring hug. In addition, the deeper sinkage combined with memory foam comfort layers creates a feeling where the body lies “in” the mattress as opposed to “on” the mattress.

The level of sinkage is documented in the image below.

This more dramatic, exacting, and precise body contouring hug helps to create amazing pressure relief. However, it’s also a more polarizing feel.

To be comfortable on the Keetsa Supreme, you’ll need to strongly prefer the feel of memory foam, lying “in” the mattress, a more dramatic body hug, and a soft feel.

The Keetsa Supreme has a low level of motion transfer. During our tests, we measured a total acceleration range of 9.16 m/s². This is 4% more motion transfer than the average of 8.79 m/s².

Typically, all-foam memory foam mattresses perform better than average for motion transfer. So I was a bit surprised to see this mattress measuring a bit higher than average.

Even so, at 4% more motion transfer than average, it’s still well within the “low” motion transfer tier. The all-foam design, memory foam comfort layer, soft feel, and deep sinkage create the right material conditions to better mitigate energy and bounce, keeping motion transfer held in check.

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

In our motion transfer chart, which visualizes our accelerometer data, we can see the highest motion peaks from 0 to 0.2 seconds. Motion declines dramatically thereafter before plummeting by 0.3 seconds.

By 0.75 seconds, we’ve returned to near-zero levels of energy, which is 0.16 seconds shorter than the average motion duration of 0.91 seconds.

Overall, motion transfer is excellent. The combination of near-average motion intensity and better-than-average motion duration creates a low-motion sleeping surface that most sleepers should be satisfied with.

The Keetsa Supreme has a fast material response. In our mostly recovered test, we measured a recovery speed of 0.4 seconds, which is 0.02 seconds faster than the average of 0.42 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 0.8 seconds, which is 0.23 seconds faster than the average of 1.03 seconds. While these material recovery speeds are far from instant, they are also not slow by any stretch.

The level of responsiveness is documented in the video below.

Memory foam is often notably slower than average, but that’s not what we measured here. Keetsa’s memory foam recovers to shape fairly quickly.

The faster responsiveness speeds help to improve ease of movement and prevent any type of stuck feeling on the mattress. Overall, I’m pleased with these responsiveness levels, and I expect most sleepers will find material recovery to be sufficient.

The Keetsa Supreme has an extremely low level of bounce. During our tests, we measured a total bounce height of 3.59″. This is 5.06″ less bounce than the average of 8.65″, based on all of our tests to date.

The lower level of bounce is a product of the all-foam design, but especially the 4.0” memory foam comfort layer. Memory foam greatly absorbs, disperses, and mitigates energy.

As a result, there is simply less energy that’s available to be returned as bounce. The lower bounce, especially in combination with the deeper sinkage and softer feel, makes this mattress harder to move around.

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

A lower bounce also negatively impacts sex performance. That being said, the low bounce is a major reason why motion transfer levels were kept in check. As a result, there are pros and cons to consider when it comes to bounce.

The Keetsa Supreme has fair sitting edge support and good lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 4.75″. This is 0.90″ more sitting sinkage than the average of 3.85″, based on all of our tests to date.

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

While lying directly on the edge of the mattress, I felt that the support was good in all sleeping positions. That said, it’s also clear that lying edge support has room for improvement.

The combination of deeper sinkage, softer feel, and a 4.0” thick memory foam layer sets the stage for less-than-amazing edge support. These material and feel factors create a weakening of support at the edge.

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

To be fair, these types of issues aren’t exclusive to Keetsa Supreme. Many memory foam mattresses and many softer mattresses can struggle more with edge support.

All that to say, if you are someone who prefers to use the edge of the mattress more, you may find this level of edge support performance isn’t ideal.

The Keetsa Supreme has mediocre sex performance. First up, let’s talk through the positives.

In our tests, we found the mattress creates minimal noise and has outstanding pressure relief. In addition, with a more middling performance, we have cooling, which earned a good, but not great, score.

Moving on, let’s talk about the negatives. Our edge support test measured sitting edge sinkage at 4.75”. This is notably deeper sinkage than average and that means the edge simply isn’t especially supportive.

The more limited edge support reduces the usable surface area of the mattress. The last big negative is bounce, which we measured at 3.59”. To put that number into perspective, it is the 3rd least amount of bounce we’ve tested to date out of 463 other bounce tests.

This level of bounce means the mattress is significantly more tiring and strenuous to have sex on.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	5.0	Very Low
Edge Support	20%	7.8	Fair
Noise	5%	10	Minimal
Pressure Relief	5%	10	Outstanding
Cooling	5%	8.0	Good

When mattresses have more bounce, they are able to create better ease of movement and accessibility on the mattress. The lack of bounce means ease of movement is considerably less, and the mattress is simply more difficult to have sex on.

The Keetsa Supreme has an outstanding level of pressure relief. During our tests, I felt no significant pressure points on my body. Overall, I found the mattress to be incredibly comfortable.

The mattress is equipped with 5.25″ of comfort material, which is 0.88″ more comfort material than the average comfort layer thickness of 4.37″, based on all of our tests to date. This mattress uses a fairly thick 1.25” comfort layer and a 4.0” layer of memory foam.

The memory foam, in particular, creates a dramatic and exacting hug around the body. In addition, we have a deep level of sinkage and a soft feel. This combination of dramatic body hug, deeper sinkage, and softer feel can create fantastic pressure relief and comfort, especially for side sleepers.

That said, this feel can also be polarizing, as not all sleepers will prefer this type of comfort dynamic. To be comfortable on the Keetsa Supreme, you’ll need to prefer a more pronounced memory foam hugging feel.

In our objective pressure mapping tests, we measured a max PSI of 0.50, which is well within the 1.0 PSI threshold we ideally want to see.

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.08	0.41

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.05	0.50

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.06	0.35

When I consider our objective pressure mapping tests, material thickness, material quality, and my subjective experience on the mattress, I’m confident most sleepers will find the pressure relief to be outstanding.

The Keetsa Supreme had a strong smell upon the initial unboxing. The mattress smelled for 7 days. This is 0.6 days shorter than the average smell duration of 7.6 days.

Keetsa mattresses come with a 90-night trial period and a 12-year warranty. Shipping is free. Returns are $169.

Company Factor	Factor Weight	Score	Data
Returns	40%	5.0	$169
Trial Period	30%	6.0	90 nights
Warranty	20%	8.0	12 years
Shipping	10%	10	$0
Country of Origin	0%		Indonesia

Comparing 121+ brands tested to date, the average trial period is 196 nights, 95 nights more than Keetsa offers. The average warranty is 13 years and that’s if we exclude the 42% of mattresses that offer lifetime warranties.

Both the trial period and warranty offered by Keetsa are shorter than average, which does hurt the company’s score. That said, the real pain point is the $169 return fee, which is incredibly high.

The Keetsa Supreme comes in a single firmness option—Soft, which we rate at a 4 out of 10 on the firmness scale, where 10 is the most firm.

The 4” layer of memory foam in the comfort layer makes for a consistent soft feel and this feel is best suited for side sleepers.

Support on the Keetsa Supreme is excellent. During our tests, I felt well supported while lying on my side and back, but did not feel well supported on my stomach.

The softer feel and deep sinkage of this mattress make it an ideal choice for side sleepers. This support dynamic helps to bring the hips into alignment with the rest of the body.

That said, this same support dynamic doesn’t work for stomach sleepers, as the increased midsection sinkage causes the spine to move out of alignment with the rest of the body.

With respect to back sleepers, I found this mattress to be supportive. That said, not all back sleepers will. This is fundamentally a soft mattress. For some back sleepers, the softer feel just won’t create enough pushback, which could create support issues.

Check out the table below to see the sleeper weights and sleeping positions that would be best suited for this mattress.

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

Moving on, the mattress is equipped with a 7.0″ support layer. This is 0.98″ thinner than the average support layer thickness of 7.98″, based on all of our tests to date.

In all mattress tests, we make it a point to cut the mattress open to examine the material quality. In doing so, we measured foam densities at 2.54 PCF and 3.5 PCF for the memory foam layers, and 2.11 PCF for the support foam. A 2.11 PCF support foam is fantastic to see, and notably more than the 1.8 PCF support foam we more typically see.

When it comes to foam density, denser foams are preferred, as they typically perform better, last longer, and sag less. For memory foam, we want to ideally see 4-6 PCF. A 3.5 PCF is within what I’d describe as the “good” tier, but we only have 0.5” of that density.

The bulk of the comfort material is a 2.54 PCF 4.0” memory foam layer. That PCF is a good bit south of what I ideally want to see. Especially when we consider the softer feel, these PCFs make me a bit concerned about the longevity of this mattress.

Based on all of my tests to date, an analysis of the materials, and my subjective experiences, I’m confident most sleepers will find support on the Keetsa Supreme is excellent.

The Keetsa Supreme is a 12.25″ memory foam mattress that comes in a single firmness option—Soft.

Within the Keetsa collection, the Supreme mattress is the higher-end memory foam mattress offered. The base-level Keetsa memory foam mattress is the Keetsa Cloud, which is a firmer option that comes in just above $1,100 for a queen mattress.

The Keetsa Supreme is 12.25″ thick and contains a combination of memory foam and support foam. From top to bottom, here is a full list of the materials used in this mattress:

Layer Type	Thickness	Manufacturer’s Specs	Tested Specs
Quilted Cover	0.75″	Not Available	Not Available
Memory Foam	0.50″	Not Available	3.50 PCF
Memory Foam	4.00″	Not Available	2.54 PCF
Support Foam	7.00″	Not Available	2.11 PCF

The Keetsa Supreme has a 0.75″ quilted cover made of a blend of polyester, tencel, and linen. It is designed to be cool and moisture-wicking, with foam quilted into the cover itself.

The comfort layer is 5.25″ thick, including the 0.75″ quilted cover. Beneath the cover, there is a 0.5″ memory foam layer followed by a 4.0″ memory foam. These three layers work together to provide the full comfort dynamic.

The support layer is 7.00″ thick and made of a single 7.0″ support foam base. This is a pretty standard support layer for a memory foam mattress and about what I’d expect from the Keetsa.

Product Evolution

The Keetsa Supreme appears to be a newer evolution of the Tea Leaf Supreme mattress. The Tea Leaf was another soft memory foam mattress that was released in 2007.

Although the exact construction of the Tea Leaf Supreme is a bit unclear, the basic design as a soft memory foam mattress has remained consistent with the Supreme throughout the years.
