How is Sleepmax Different?

The Sleepmax is a 12″ hybrid mattress with an overall performance level that is significantly worse than the average hybrid, but also a price tag that is also significantly lower, a savings of 75% compared to the average hybrid.

Advantages

The only real advantage of the Sleepmax is the low cost. Hybrids under $500 are extremely rare in the market, but the Sleepmax manages to cut enough corners to hit that ultra-low price.

Neutral Factors

The mattress has moderate levels of sinkage and high levels of bounce. These factors are considered neutral since different sleepers may have different preferences for mattress feel.

Disadvantages

The Sleepmax will get you a hybrid for an unbelievably low price, but be prepared to give up significant features in terms of performance.

Cooling, motion transfer, response time, edge support, pressure relief, and off-gassing all have a performance that is well below the average. This mattress only has a 3.0″ comfort layer, 30% thinner than the average thickness layer (4.3″).

Lastly, it appears that this mattress does not come with any type of warranty. For context, 40% of all mattresses we’ve tested have a lifetime warranty on their mattresses. The average of the other 60% of mattresses is 13 years.

While Sleepmax does include some language on this topic, they seem hesitant to use the actual term “warranty”. On the product listing, Sleepmax refers to some kind of “10-year service agreement” as well as “lifetime care”, but each of these leaves out the critical word “warranty”.

Not calling these services an actual “warranty” and the fact there is no warranty page or document leads me to believe that they do not offer the same level of protection as a legally binding product warranty. I have reached out to Sleepmax for further clarification and comment on the warranty, but as of the initial publication of this review we have not received any response from Sleepmax.

The Sleepmax has fair cooling. During our tests, I felt a moderate level of heat retention around my body.

The mattress certainly seemed to struggle with cooling, as we measured notably higher than average max temperatures and also experienced more retained heat and hot spots on the mattress.

• 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

The foams look and feel lower quality and they seem to have a harder time releasing heat and breathing.

Fortunately, we do have a hybrid design, which is bringing extra airflow in. Even so, the hybrid design alone just wasn’t enough to facilitate ideal cooling performance.

In our objective temperature tests, we measured a max surface level temperature of 91.8° F. This is 1.9° more than the average of 89.9° F, based on all of our tests to date.

After getting off the mattress, the temperature declined by 4.1 degrees from minutes 0 to 1, which is 0.7 degrees warmer than the average 0 to 1 minute decline of 4.8 degrees.

Heat Dissipation Over Time

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 fair.

The Sleepmax has moderate sinkage. During our tests, we measured a pressure point sinkage depth of 2.04″.

This is 0.17″ less sinkage than the average sinkage depth of 2.21″, based on all of our tests to date. The mattress creates a balanced body contouring hug.

The level of sinkage is documented in the image below.

While the hug is balanced, the overall feel and comfort dynamic feels like a typical, cheap hybrid mattress. The mattress has lots of bounce and movement. In some ways, it feels more like a traditional coil mattress and less like a hybrid.

The Sleepmax uses a relatively thin 3.0” comfort layer with 2.0” coming from the quilted cover. This comfort layer is considerably thinner than average and the ratio of quilted foam vs. other comfort foams is far from ideal.

The Sleepmax has an extremely high level of motion transfer. During our tests, we measured a total acceleration range of 16.49 m/s². This is 88% more motion transfer than the average of 8.79 m/s².

The hybrid design, thinner than average comfort layer, and (in my view) low-quality foams and low-quality coil unit create the material conditions to create extremely high motion transfer.

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.

Next we see a secondary motion spike from 0.50 to 0.70 seconds. It’s not until 0.93 seconds that we return to near-zero levels of energy.

Motion Transfer Over Time

Motion duration is only slightly worse than average, but the motion intensity is 7th 7th-highest acceleration we’ve ever tested. There is simply no sugar coating it. The Sleepmax has extremely high motion transfer and, as a result, isn’t a great choice for couples.

The Sleepmax has a very slow material response. In our mostly recovered test, we measured a recovery speed of 1.2 seconds, which is 0.77 seconds slower than the average of 0.43 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 3.5 seconds, which is 2.51 seconds slower than the average of 0.99 seconds. The Sleepmax is a tale of two materials.

The coil unit within the mattress springs back to shape effectively instantly, which certainly helps the material’s responsiveness.

The level of responsiveness is documented in the video below.

However, the foams used within this mattress have an incredibly slow recovery, which results in a very slow material responsiveness. That slower responsiveness makes this mattress harder to move around on and creates more of a “stuck” feeling.

The Sleepmax has a high level of bounce. During our tests, we measured a total bounce height of 10.04″. This is 1.14″ more bounce than the average of 8.90″, based on all of our tests to date.

The same factors that created higher motion transfer also create more bounce. The thinner-than-average comfort layer and lower-quality foams, which simply don’t suppress energy to the same degree as higher-quality foams, in combination with the hybrid design, are able to deliver more bounce than average.

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

That extra bounce is a major reason why motion transfer is higher. However, the extra bounce also improves sex performance. So there are pros and cons worth considering.

The Sleepmax has good sitting edge support and good lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 4.25″. This is 0.29″ more sitting sinkage than the average of 3.96″, 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.

The Sleepmax is equipped with reinforced coils that run along the perimeter of the edges. These coils are the primary reason that edge support was fairly good.

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

I was quite surprised to see reinforced edge coils, as normally you only see this design feature in more expensive mattresses. All that said, overall edge support is surprisingly good, especially given the price point.

The Sleepmax has good sex performance. First, let’s talk through the positives. Bounce and edge support both earned good scores.

We measured bounce at 10.04”, which is notably higher than average. When it comes to sex performance, more bounce is almost always better.

The higher bounce helps make sex less strenuous and less tiring. In addition, the edge support is surprisingly robust. With just 4.25” of sitting edge sinkage, the edge is supportive enough to be a usable part of the mattress for amorous activities.

Moving on with a middling score, we have noise, which we rated a moderate level. This certainly isn’t ideal, but it’s still a reasonably good performance level at this price point.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	8.8	High
Edge Support	20%	8.4	Good
Noise	5%	8.0	Moderate
Pressure Relief	5%	6.0	Mediocre
Cooling	5%	7.0	Fair

Next up, we have the cons which include pressure relief and cooling, both of which left much to be desired. Despite the weaker performance from pressure relief and cooling the overall sex score is good, primarily thanks to the above average bounce height.

The Sleepmax has a mediocre level of pressure relief. During our tests, I felt significant pressure points on my body and, in general, found the mattress to be uncomfortable.

The mattress is equipped with 3.0″ of comfort material, which is 1.27″ less comfort material than the average comfort layer thickness of 4.27″, based on all of our tests to date.

When I look at the quality of the foam layers I am just not happy with what I see. The foams look and feel incredibly basic and lower quality, both on the body and in-hand.

It’s also relatively thin at just 3.0” of comfort material, which is all the more problematic considering the relatively low quality of the foams.

The thinner-than-average comfort layer, combined with the poor foam quality, makes me incredibly concerned about the longevity of this mattress. I just don’t expect this mattress to last very long.

Moving on, we have a 9.0” coil unit, which is a good height, however, the quality of the coil unit looks and feels incredibly low quality. It also is a significant reason for the extremely high motion transfer. The quality of coil unit makes me incredibly doubtful that this mattress will last very long.

In our pressure mapping tests, we measured a max PSI of 1.10.

Pressure Map – Side Sleepers

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.13	1.10

Pressure Map – Back Sleepers

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.08	0.68

Pressure Map – Stomach Sleepers

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.08	0.48

When it comes to pressure maps, lower PSI is better and ideally I want to see notably less than 1.0 PSI. Suffice to say, at a PSI of 1.10 there are clear pressure issues lighting up in the hips.

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 mediocre.

The Sleepmax had a strong smell upon the initial unboxing. The mattress smelled for 12 days. This is 5.8 days longer than the average smell duration of 6.8 days.

Sleepmax mattresses come with a 365-night trial period and does not come with any warranty. Shipping and returns are both free.

Company Factor	Factor Weight	Score	Data
Returns	40%	10	$0
Trial Period	30%	10	365 nights
Warranty	20%	0.0	0 years
Shipping	10%	10	$0
Country of Origin	0%		USA

Comparing 100+ brands tested to date, the average trial period is 170 nights, 195 nights less than Sleepmax offers. The average warranty is 13 years and even that data excludes the 40% of mattresses that offer lifetime warranties on their mattresses.

From what I can tell, the Sleepmax mattress, sold and distributed on Amazon, does not include a product warranty. They do include some nice-sounding language that refers to a “10-year service agreement” as well as “lifetime care”, but as I mentioned above, these are not actually called warranties anywhere on the product page.

When I look for the URL or document with the warranty information I was not able to find it.

Using any word besides “warranty” leads me to believe that they do not offer the same level of protection as an actual product warranty would.

The Sleepmax mattress comes in a single firmness, medium-firm, which comes in at 6 out of 10 on our firmness scale.

This firmness is generally considered to be suitable for a wide range of sleepers and preferences.

Support on the Sleepmax is mediocre. During our tests, I did not feel supported on the mattress. The mattress is equipped with a 9.0″ support layer.

This is 1.08″ thicker than the average support layer thickness of 7.92″, based on all of our tests to date.

While the mattress has a support layer and total height thickness that is generally associated with a more supportive feel, that is not what we experienced on the Sleepmax.

The coil unit simply feels incredibly cheap. This coil unit, combined with the thinner-than-average comfort layer and lower-quality foam materials, means it’s easy to feel those coils on your body.

It’s also easy to bottom out the mattress while moving around, getting in and out of bed, changing positions, and during amorous activities.

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.	Yes	Yes	Yes
150-250 lbs.	Yes	Yes	Yes
250-300 lbs.	Yes	Yes	Yes

When you combine the below-average coil unit performance with a below-average pressure relief performance, it creates a below-average support performance.

In my view, this mattress simply does not have sufficient material quality to create an ideal level of support. Based on all of my tests to date, an analysis of the materials, and my subjective experiences, I’m confident that most sleepers will find support on the Sleepmax is fair.

Design

The Sleepmax is a 12″ hybrid mattress that comes in a single firmness option—Medium-Firm.

Materials

The Sleepmax is 12″ thick and contains a combination of foam, coils, and a quilted cover. From top to bottom, here is a full list of the materials used in this mattress:

• 2.0” quilted cover
• 1.0” poly foam
• 9.0” pocketed coils

The Cover

The Sleepmax has a 2.0″ foam-filled quilted cover. The cover fabric itself is a blend of mostly rayon (85%) and polyester (15%). It lacks any handles on the mattress, but does use a reinforced fabric on the sides, which helps to make the sides a bit more durable.

The Comfort Layer

The comfort layer is 3.0″ thick and includes the 2.0″ quilted cover followed by the 1.0″ poly foam comfort layer. Only having 1.0″ of comfort material that is separate from the quilted cover is extremely thin.

It’s the lack of material thickness (as well as a lack of material quality) within this layer that hurts the pressure relief score and gives the mattress generally worse support than mattresses with thicker comfort layers.

The Support Layer

The support layer is 9″ thick and made of a pocketed coil unit. There are stronger coils used at the edges of the mattress for reinforced support (as indicated in blue).

Generally speaking, the support layer of a 12″ hybrid would include 8.0″ of pocketed coils and 4.0″ of foam. The Sleepmax takes a modified approach by opting for 9.0″ of coils and 3.0″ of foam.

I wouldn’t say that the extra 1.0″ of coil improves support in a significant way, but its worth noting the difference compared to average.

Product Evolution

Sleepmax is actually an older sleep brand that appears to have changed hands a couple of times, with its origins as a mattress company dating back to 1983.

Sleepmax mattresses are most prevalent on the Amazon marketplace and seem to have made their debut between 2023 and 2025, depending on what product you’re looking at.

We first tested the Sleepmax hybrid in 2025 and did not see any notable design changes between earlier versions and the mattress we tested.

That being said, there are many different Sleepmax mattresses available, varying in thickness and material type. You will likely see these slight variations between Sleepmax mattress versions.
