How is Sleepmax Omnifit Different?

The Sleepmax Omnifit is a 12.00″ hybrid mattress with an overall performance level that is right at the average level, paired with a price that is significantly below average. Compared to the average hybrid, the Omnifit saves sleepers 47% off the average—a total savings of $695 on the queen mattresses.

Advantages

Aside from the low price, other advantages of the Omnifit include lower levels of motion transfer, fantastic edge support, and a great sex score as well.

It is backed by a 365-night trial period and a lifetime warranty, which helps to give Sleepmax a great company score.

Neutral Factors

This mattress has minimal sinkage and high levels of bounce. This gives more pushback than the average mattress, but can be a good fit for sleepers who don’t want to engage too deeply or feel overly enveloped by the mattress.

Disadvantages

The biggest disadvantages of the Omnifit would be worse pressure relief and slower off-gassing. This mattress only has a 2.5″ comfort layer, which is 42% thinner than the 4.32″ average comfort layer thickness.

The Sleepmax Omnifit has good cooling. During our tests, I felt a slight level of heat retention on my body, but it was nothing extreme or anything I’d describe as “hot”.

The Omnifit is a hybrid mattress. We have a 2.50” comfort layer that sits atop an 8.50” coil unit. While the thinner-than-average comfort layer isn’t doing any favors for pressure relief, at least for cooling, it’s beneficial, as there is simply less material in which heat can be easily absorbed and retained within.

In addition, having an 8.50” coil unit is helping to bring more airflow into the mattress. According to the product page, this mattress is equipped with a cooling cover that lowers “contact temperature by 5–8°”.

While the cooling cover does have a slightly cool feel initially, within a few minutes of lying on the mattress most of that cooling sensation was gone. To be fair, it’s still a nice cover, but I don’t think it’s necessarily a miracle worker when it comes to cooling.

• 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 our objective temperature tests, we measured a max surface level temperature of 91.5° F. This is 1.4° warmer than the average of 90.1° F, based on all of our tests to date.

After getting off the mattress, the temperature declined by 4.2 degrees from minutes 0 to 1, which is 0.6 degrees warmer 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 Sleepmax Omnifit has minimal sinkage. During our tests, we measured a pressure point sinkage depth of 1.95″. This is 0.30″ less sinkage than the average sinkage depth of 2.25″, based on all of our tests to date.

The level of sinkage is documented in the image below.

The mattress creates only a slight level of body contouring or hug. The combination of a thinner-than-average comfort layer, firm feel, and minimal sinkage creates more of a floating feel. Instead of sinking down “in” the mattress, you’ll float more “on” the mattress.

This is certainly more of a polarizing feel. While some sleepers will enjoy the feel, a majority will not, in my view. Side sleepers, especially, are not well supported with this comfort dynamic. As a result, the Omnifit firm version is better for stomach and back sleepers.

All that said, most sleepers should choose the medium version of the Omnifit, which is simply a better fit for a wider range of preferences and all sleeping positions.

The Sleepmax Omnifit has a very low level of motion transfer. During our tests, we measured a total acceleration range of 6.91 m/s². This is 22% less motion transfer than the average of 8.84 m/s².

Typically, firmer mattresses with more bounce struggle with more motion transfer; however, the Omnifit performed surprisingly well.

Notably, the mattress does use a 1.0” memory foam layer in the core. This layer seems to be having an outsized impact on overall performance, as memory foam does a great job at absorbing and dispersing energy.

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 thereafter, but we do see a small secondary energy spike from 0.50 to 0.60 seconds.

By 0.95 seconds, we’ve returned to near-zero levels of energy, which is 0.06 seconds longer than the average motion duration of 0.89 seconds.

While the motion duration is slightly longer than average, the motion intensity is well below average. Overall, I’m pleased with this level of motion transfer, and I don’t expect it to be a problem for most sleepers.

The Sleepmax Omnifit is a mixed bag for material responsiveness, with a fast mostly recovered response time and a moderate fully recovered response time.

In our mostly recovered test, we measured a recovery speed of 0.4 seconds, which is 0.01 seconds faster than the average of 0.41 seconds, based on all of our tests to date.

In our fully recovered responsiveness test, we measured a recovery speed of 1.2 seconds, which is 0.18 seconds slower than the average of 1.02 seconds. The Omnifit uses a mix of material types.

The level of responsiveness is documented in the video below.

The poly foam and coils within the mattress spring back to shape effectively instantly. However, the 1.0” memory foam layer in the core takes considerably longer to fully reform back to shape. It’s this memory foam layer that’s slowing down the full material recovery speed.

While the full responsiveness is slower than average, it doesn’t have a tremendous negative impact on ease of movement. The combination of more responsive poly foam on top, thin cover, minimal sinkage, firm feel, and high bounce works together to counteract the negative impact of slower response and create good ease of movement.

The Sleepmax Omnifit has a high level of bounce. During our tests, we measured a total bounce height of 10.33″.

This is 1.61″ more bounce than the average of 8.72″, based on all of our tests to date.

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

The Omnifit creates more bounce than average due to a combination of the firm feel, minimal sinkage, a thinner-than-average comfort layer, and tall coil unit. In addition, the poly foam top comfort layer is highly responsive and resilient.

These material and design choices create a high degree of pushback, which delivers higher bounce than average. That increased bounce is a major factor in improving sex performance and also has a positive impact on ease of movement.

The Sleepmax Omnifit has outstanding sitting edge support and outstanding lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 2.75″. This is 1.14″ less sitting sinkage than the average of 3.89″, 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 outstanding in all sleeping positions.

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

This mattress is equipped with a reinforced edge support foam. That foam runs along the entire perimeter of the mattress. This design feature, in addition to the firm feel, minimal sinkage, and thinner than average comfort layer, are working together to create an incredibly robust and supportive edge support.

To be fair, the firm feel is likely having an outsized impact on edge support. I would expect the medium and plush versions of this mattress to earn good edge support scores, but not outstanding scores.

The Sleepmax Omnifit has excellent sex performance. On the positive side, noise is minimal and edge support earned an outstanding score. With just 2.75” of sitting edge sinkage, the edge is incredibly robust and supportive. The more supportive edge extends the usable surface area of the mattress.

In addition, bounce is high, earning a good score. We measured 10.33” of total bounce height, which is notably higher than average. That extra bounce makes sex easier and less tiring. Moving on, cooling also earned a good, but not a great score.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	8.9	High
Edge Support	20%	10	Outstanding
Noise	5%	10	Minimal
Pressure Relief	5%	7.0	Fair
Cooling	5%	8.0	Good

It’s good enough that it shouldn’t be a major hindrance, but clearly it has room for improvement. Lastly, we have pressure relief, which we rated at fair. The thinner-than-average comfort layer, while beneficial for bounce and edge support, is having a negative impact on pressure relief and overall comfort.

Despite the weaker pressure relief, the overall sex performance score is still excellent.

The Sleepmax Omnifit has a fair level of pressure relief. During our tests, I felt slight to moderate pressure points on my body.

The mattress is equipped with 2.5″ of comfort material, which is 1.82″ less comfort material than the average comfort layer thickness of 4.32″, based on all of our tests to date.

In all mattress tests at NapLab, we make it a point to cut the mattress open to examine the material quality. While the foam quality isn’t incredible, it’s not bad either.

It’s a fair and reasonable level of quality at this price point. That said, I do wish we had a little more of it. The thinner-than-average comfort layer is the most significant reason why pressure relief failed to earn a better score.

To be fair, we tested the firm version, which has an intentionally thinner comfort layer to deliver more firmness. The medium and plush versions of the Omnifit are thicker and use a thicker comfort layer, which almost certainly will improve pressure relief in those versions of the mattress.

In our objective pressure mapping tests, we measured a max PSI of 0.54. Ideally, I want to see all PSI measurements at 1.0 or less and the Omnifit easily cleared that mark.

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.10	0.52

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.07	0.54

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 fair.

The Sleepmax Omnifit had a strong smell upon the initial unboxing. The mattress smelled for 8 days. This is 0.7 days longer than the average smell duration of 7.3 days.

Sleepmax mattresses come with a 365-night trial period and a lifetime warranty. Shipping and returns are both free.

Comparing 110+ brands tested to date, the average trial period is 181 nights, 184 nights less than Sleepmax offers. This mattress is also backed by a lifetime warranty, which is a perk offered by only 40% of mattresses tested to date.

The SleepMax Omnifit Hybrid is available in 3 firmness options – Firm, Medium, and Plush. Our tests were performed on the firm version, and we rate it at an 8 out of 10, where 10 is the most firm.

While not testing the Medium version first-hand, we estimate that it has a rating of 6 out of 10, which gives it a medium-firm feel.

Likewise, we would estimate the Plush option at a 4 out of 10, which gives it a soft feel.

Support on the Sleepmax Omnifit is good. During our tests, I felt well supported on my back and stomach, but not on my side.

Support Factor	Data
Comfort Layer	2.50″
Support Layer	9.50″
Firmness	Soft, Medium-Firm, and Firm
Body Contour	Slight
Zoned Support	No
Reinforced Edge	Yes

The less-than-great support on my side is a product of the firm feel. Firmer mattresses are best for stomach and back sleepers, but not typically ideal for side sleepers. Notably, this mattress is also available in a medium and plush version.

If you are a side sleeper, I would encourage you to go with one of these softer options. The vast majority of sleepers will be best served by the medium version. The mattress is equipped with a 9.5″ support layer. This is 1.58″ thicker than the average support layer thickness of 7.92″, based on all of our tests to date.

Notably, the firm version creates more of a floating feel where sleepers like “on” the mattress instead of sinking down “in” the mattress. This floating feel combined with the minimal sinkage depth and firm feel creates a polarizing feel. Some may love it, but many will not.

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

Plush Version, 14″

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

Medium Version, 13″

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

Firm Version, 12″

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

To feel well supported and comfortable on the firm version, you’ll need to strongly prefer this comfort dynamic. If you’re unsure about the firmness that’s best for you, then I would strongly encourage going with the medium version.

The medium version will have a more balanced support dynamic that is appropriate to all sleeping positions. Lastly, this mattress does not utilize zoned support. Instead, we have a consistent firmness from head to foot of the mattress.

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 Omnifit to be good.

The Sleepmax Omnifit is a 12.00″ hybrid mattress that comes in three firmness options—Plush, Medium, and Firm. It enters the mattress market as a budget-friendly hybrid, hitting a price that not many hybrids do, while still offering a range of firmness options.

Design Factor	Data
Type	Hybrid
Thickness	12.00″
Cover Type	Thin
Weight	78 lbs.
Has Handles	Yes
Fiberglass-Free	Yes
Ships in a Box	Yes

It is 12″ thick with a thin cover and fiberglass-free materials. There are no handles on the sides of the mattress, and overall, the Omnifit has a pretty basic design.

The Sleepmax Omnifit is 12.00″ thick and contains a combination of foam and coils. From top to bottom, here is a full list of the materials used in this mattress:

Layer Type	Thickness	Layer Specs
Poly Foam	1.00″	1.5 PCF, 20 ILD
Memory Foam	1.00″	2.375 PCF, 9 ILD
Pocketed Coils	8.50″	14.5 Gauge
Edge Support Foam Encasement	4.00″	2.19 PCF, 30 ILD
Support Foam	1.00″	1.5 PCF, 20 ILD

The Sleepmax Omnifit has a thin cover. Aesthetically, Sleepmax added some hexagon design elements to help the mattress have a visual “pop” to the cover.

The sides have a contrasting black accent bar, which provides contrast and gives the mattress a modern look.

But looks aside, there is not really anything truly special bout the Omnifit mattress cover. That said, given the low price, it’s about what I expected at this price, and it’s perfectly acceptable.

The comfort layer is 2.50″ thick and made of two layers of foam. Directly below the cover is a 1.0″ poly foam (green foam) followed by a 1.0″ memory foam (yellow foam).

This mattress’s comfort layer is only 2.5″ thick. The average comfort layer is 4.3″ thick, so the Sleepmax really falls short in this area.

Lacking enough comfort material is one of the quickest ways to earn a lower pressure relief score, which is exactly what we see on the Omnifit.

The support layer is 9.50″ thick and made of an 8.5″ pocketed coil base followed by a 1.0″ support foam layer. For a hybrid, this is exactly the type of support base I’d expect to see here.

Product Evolution

Sleepmax is a newer company, and the Omnifit appears to have just recently launched in January 2026. Given that it’s a newer mattress to the market, there have been no changes made since its initial release.
