How is Tiami Different?

The Tiami is a 12″ hybrid mattress with an overall performance level that is well above the average level, but also a price tag that is higher than average.

Advantages

Advantages include excellent cooling performance, extremely fast material response time, better edge support, and great pressure relief. This mattress is a 12″ thick mattress (about average), but has a 5.0″ comfort layer, 0.9″ thicker than average.

Neutral Factors

The Tiami has very minimal sinkage and low levels of bounce. As you’ll read in this review, this mattress has a surprising amount of pushback, which may be a pro or con, depending on what type of feel you’re looking for in a mattress.

Disadvantages

The Tiami’s disadvantages include a less-impressive sex score, thanks largely to the lower level of bounce. The trial is also only 100 nights, 71 nights shorter than the average trial period. This mattress comes with a 10-year warranty. That said, 41% of the mattresses we test offer a lifetime warranty.

The Tiami has outstanding cooling. During our tests, I did not feel any significant level of heat retention around my body.

The mattress uses a thin knit cover that is highly breathable and allows air to easily flow in and out. This is in contrast to quilted covers, euro tops, and pillow tops, which can sometimes prevent airflow due to how densely the materials are packed inside.

In addition, the comfort material is primarily poly foam, as opposed to memory foam. Poly foam is simply more breathable than most types of memory foam and does a nice job at avoiding heat retention.

Lastly, we have the hybrid design itself, which brings plenty of airflow into the mattress via a 7.0” pocketed coil unit (which is 10.0” around the perimeter).

• 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 89.4° F. This is 0.4° less than the average of 89.8° F, based on all of our tests to date.

After getting off the mattress, the temperature declined by 5.2 degrees from minutes 0 to 1, which is 0.6 degrees cooler than the average 0 to 1 minute decline of 4.6 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 outstanding.

The Tiami has very minimal sinkage. During our tests, we measured a pressure point sinkage depth of 1.66″. This is 0.52″ less sinkage than the average sinkage depth of 2.18″, based on all of our tests to date. The mattress creates a slight body contouring hug.

The level of sinkage is documented in the image below.

The mattress has more of a floating feel where the body lies more “on” the mattress as opposed to sinking down “in” the mattress. This floating feel is more significant for lighter parts of the body (arms, legs, head), as they simply don’t weigh enough to press further down into the mattress.

That said, heavier weighted parts of the body, especially butt and midsection, do sink down to a more moderate depth.

Even so, there is not a notable body contouring hug with this mattress and there absolutely is more of a floating feel for sleeper bodies. This is neither good nor bad, but it is a more specific feel, one you’ll need to prefer to be comfortable on the Tiami.

The Tiami has an extremely low level of motion transfer. During our tests, we measured a total acceleration range of 5.07 m/s². This is 41% less motion transfer than the average of 8.66 m/s².

The Tiami’s material design is helping to keep motion transfer lower. First, the cover is loose enough that it doesn’t tug back and forth with sleeper movements.

In addition, the combination of a 5.0” comfort layer, including free-floating foam cubes that sit atop the pocketed coil unit, is reducing bounce and isolating motion across the mattress.

Both of these have a positive impact on reducing motion intensity and motion duration.

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 0.15 seconds. Immediately thereafter, motion declines notably and by 0.94 seconds we return to near-zero levels of energy.

While motion duration is a bit longer than I expected, it’s nothing that should be problematic for most sleepers.

At the end of the day, the motion intensity is incredibly low, especially for a hybrid mattress with mostly poly foam comfort layers. Overall, I’m pleased with the motion transfer and don’t expect it will be an issue for most sleepers.

The Tiami has an extremely fast material response. In our mostly recovered test, we measured a recovery speed of 0.2 seconds, which is 0.22 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 0.3 seconds, which is 0.69 seconds faster than the average of 0.99 seconds.

The level of responsiveness is documented in the video below.

This is effectively an instant material response time and is tied for 1st as the fastest responding mattress we’ve tested to date with a number of other highly responsive mattresses.

The rapid material responsiveness ensures that the mattress is easy to move around on and you’ll never feel stuck or overly enveloped by the mattress.

The Tiami has a low level of bounce. During our tests, we measured a total bounce height of 6.57″. This is 2.59″ less bounce than the average of 9.16″, based on all of our tests to date.

The lower level of bounce is most likely resulting from the unique design of the Tiami. Tiami uses a 5.0” foam comfort layer. However, the bottom 3.0” of foam are individually cut foam cubes that are encased in fabric sitting atop the pocketed coil unit.

In my view, this type of foam design absorbs and disperses a ton of energy, which results in a lower level of bounce.

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

To be fair, it also means motion transfer is lower. Nevertheless, bounce is a double-edged sword. Yes, the lower bounce means motion is lower, but it also means that sex performance is negatively impacted as well.

Fortunately, the lower bounce doesn’t have a major impact on ease of movement due to the very minimal sinkage depth and extremely fast material responsiveness.

The Tiami has good sitting edge support and outstanding lying edge support.

In our sitting edge support test, we measured a sitting sinkage compression of 4.25″. This is 0.25″ more sitting sinkage than the average of 4.00″, based on all of our tests to date.

While sitting edge support was good, the lying edge support felt notably better.

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 Tiami is equipped with robust reinforced coils along the perimeter of the mattress.

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

These coils are extra tall, at 10.0”, and create a ton of pushback at the very edge of the mattress.

When you combine the reinforced perimeter coils with high-quality materials and a thicker-than-average total profile height, it’s easy to see why the edge support performs as well as it does.

The Tiami has fair sex performance. First up, let’s talk through what Tiami does well. Noise is minimal, cooling is outstanding, and pressure relief is excellent. So at a minimum, it’s a comfortable mattress that isn’t going to be loud.

Edge support for sitting earned the mattress a good score with 4.25” of sitting edge compression. Absolutely, there is room for improvement here, but for most sleepers, this level of edge support performance should be more than sufficient.

Where the Tiami is weak for sex is simply bounce. At just 6.57” of total bounce height, it’s notably less bounce than average.

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	6.6	Low
Edge Support	20%	8.4	Good
Noise	5%	10	Minimal
Pressure Relief	5%	9.0	Excellent
Cooling	5%	10	Outstanding

That lower bounce means sex can be more tiring and strenuous. The overall sex score is worse than average and leaves much room for improvement.

At the same time, the lower bounce is also a major reason for the significantly better-than-average motion transfer, so there are pros and cons to consider here.

The Tiami has an excellent level of pressure relief. During our tests, I felt no significant pressure points on my body.

The mattress is equipped with 5.0″ of comfort material, which is 0.88″ more comfort material than the average comfort layer thickness of 4.12″, based on all of our tests to date.

The Tiami has a more unique design (I’ve only seen one other mattress even close to similar, the Saatva RX) and that creates a more unique feel.

We have 5.0” of comfort foam, most of which is poly foam (a branded foam called Energex). The bottom 3.0” of foam is shaped into a standalone cube that sits on top of the pocketed coil unit.

This foam configuration, in combination with the thin non-quilted cover, foam density, and slightly firm feel, creates more of a floating feel on the mattress with very minimal sinkage.

Lighter parts of the body float more on top of the mattress and even heavier parts of the body aren’t sinking tremendously deep.

In my view, this comfort dynamic limits the pressure relief performance. Much of the body is lying “on” the mattress as opposed to “in” it, and this creates quite a lot of pushback.

All that to say, this isn’t a bad level of pressure relief at all. But it is a more specific type of a feel, one you’ll need to prefer to get the most out of the Tiami’s design.

In our pressure mapping tests, we measured a max PSI 0.85. This is well within the low-pressure threshold that we look for (a 2.0 PSI is a very high and concerning pressure).

Pressure Map – Side Sleepers

Pressure Relief (PSI)	Average	Maximum
Side Sleepers	0.13	0.79

Pressure Map – Back Sleepers

Pressure Relief (PSI)	Average	Maximum
Back Sleepers	0.09	0.85

Pressure Map – Stomach Sleepers

Pressure Relief (PSI)	Average	Maximum
Stomach Sleepers	0.09	0.75

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 excellent.

The Tiami had a strong smell upon the initial unboxing. The mattress smelled for 5 days. This is 1.5 days shorter than the average smell duration of 6.5 days.

Tiami mattresses come with a 100-night trial period and a 10-year warranty. Shipping and returns are both free.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	8.0	100 nights
Warranty	10%	8.0	10 years
Shipping	5%	10	$0
Returns	20%	10	$0
Trust	50%	8.0	Good
Country of Origin	0%		USA

Comparing 99+ brands tested to date, the average trial period is 171 nights, 71 nights more than Tiami offers. The average warranty is 13 years, which is 3 years more than this mattress, and that’s if we exclude the 41% of mattresses that offer lifetime warranties.

The Tiami has a slightly firm feel, 7 out of 10 on our firmness scale, but the Tiami paints a bit of a complex picture. I was surprised at the feel and level of firmness.

As a result, I asked all of our team to test this mattress and give their assessment. Initially, I thought it was just me finding the mattress firmer, but it’s clearly something that many types of sleepers and bodies experience as a slightly firm feel.

The results below show the different firmness assessments from four different sleep experts on our team:

Tester	Firmness	Feel
Derek	7	Slightly Firm
Samantha	7 – 7.5	Slightly Firm
Kyle	6	Medium-Firm
Nate	6.5 – 7	Slightly Firm

The very minimal sinkage depth, floating feel, and slightly firm feel create a high degree of pushback that may catch some sleepers by surprise if you’re looking for deeper contour and sinkage.

Support on the Tiami is outstanding. During our tests, I felt well supported in all sleeping positions.

The mattress is equipped with a 7.0″ support layer. This is 0.92″ thinner than the average support layer thickness of 7.92″, based on all of our tests to date.

I am exceedingly impressed with the material quality of the support layers. The pocketed coil unit is quite unique. It’s 7.0” tall in the middle and 10.0” along the edge. The edge coils are extra firm for improved edge support.

The 7.0” coils in the middle are topped with 3.0” foam cubes. These foam cubes are encased within the fabric, but individually cut for each pocketed coil.

In our testing, this design configuration created incredibly low motion transfer, in addition to delivering fantastic support. The mattress has very minimal sinkage, which could be a bit polarizing while the mattress breaks in.

However, I do think this will be a benefit for sleepers over time, as the increased support, pushback, and minimal sinkage will likely lead to less sagging and fewer body impressions.

The choice to use a thin cover as opposed to a quilted, euro top, or pillow top also helps to resist sagging. Mattress sagging is among the most common reasons that a mattress feels unsupportive and uncomfortable as it ages.

Moving on, this mattress has a slightly firm feel. This firmness is best for stomach and back sleepers, though any sleeper who is okay with a little more pushback and less sinkage could find this dynamic to be comfortable.

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

The only sleeper group I’m more concerned by is lighter-weight side sleepers, as the extra support could be problematic.

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 Tiami is outstanding.

Design

The Tiami is a 12″ hybrid mattress that comes in a single firmness option—Slightly Firm. This mattress uses traditional comfort foam and pocketed support coils, but also free-floating foam blocks, which enhance pressure relief and give the mattress a more unique feel.

Materials

The Tiami is 12″ 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:

• 1.0” poly foam
• 1.0” memory foam
• 10.0” pocketed coils (3.0” poly foam cubes on top of pocketed coils)

The Cover

The Tiami has a thin cover, with organic stitching patterns that give the mattress an embossed look. The cover is stretchy and breathable, but lacks any handles on the side of the mattress.

The Comfort Layer

The comfort layer is 5.0″ thick, counting the 3.0″ foam blocks directly above the support layer (not visible in the photo below).

Directly below the cover, there are two layers of foam. On top, there is a 1.0″ poly foam (green) and the second layer is a 1.0″ memory foam (off-white).

The foam blocks are integrated into the same fabric casing as the support coils themselves. The 3.0″ block is placed at the top of the pocketed coil and repeated across the interior of the mattress.

Reinforced coils, without blocks, are used for the two rows of coils closest to the perimeter of the mattress. This helps to give the mattress better edge support when sitting or lying at or near the edge.

This unconventional design helps to improve pressure relief and comfort for sleepers of all positions. But at the end of the day, the mattress still ends up with a higher degree of pushback and a slightly firm feel.

The Support Layer

The support layer is 7″ thick and made of pocketed coils. These coils continue all the way to the base of the mattress, with no additional foam used (besides the comfort foam towards the top).

Product Evolution

Tiami is a brand-new brand, having just launched in 2025. Given its shorter history, there have been no changes made to the mattress since we first started testing the mattress.

The team behind Tiami include the original founders of the Leesa mattress. So while it is a new company, the founders have a long and successful history building quality mattresses.
