Tiami’s documented strength is exceptional cooling and motion isolation from a single, carefully designed luxury hybrid. Tiami was founded by Jamie Diamonstein and David Wolfe, the co-founders of Leesa Sleep, according to Furniture Today. Instead of a large lineup, they built one mattress. Diamonstein, the chief product officer, told press he believes simplicity is the very essence of luxury, and on Kara Goldin’s podcast he described designing it from a blank canvas after more than 40 years in the mattress industry.
Independent testing backs up the design. NapLab gave Tiami an overall score of 9.29, placing it among the top-rated hybrid mattresses it has tested, with perfect 10/10 scores for cooling and motion isolation. NapLab rated it slightly firm at 7 out of 10, measured very minimal sinkage, and said it suits all sleeping positions and body weights. NapLab describes a 12-inch build with poly foam, memory foam, free-floating foam cubes and a 7-inch pocketed coil unit that rises to 10 inches at the perimeter for edge support.
Tiami launched with Design Within Reach as its exclusive retail partner, making it DWR’s only third-party branded mattress and its first hybrid. Shoppers can try it at select DWR locations. The Daily Beast’s tester said a week on the mattress changed the way she sleeps, backed by her Oura Ring data, and noted that Architectural Digest named it a Designer Pick. NapLab lists a queen at $1,957, while Tom’s Guide reported a queen list price of $2,995.
The honest caveat: Tiami is expensive and new, so long-term owner evidence is thin. NapLab notes the queen costs 31% more than the average hybrid it has tested. Tom’s Guide said it expected better benefits for the premium price. Tiami offers only one firmness, which may not suit every sleeper. DWR’s Canadian product page shows a 3.4 out of 5 customer rating, and we couldn’t find a Trustpilot profile, so independent customer feedback is limited.

Why Trust This Review
This review draws on NapLab’s lab testing, The Daily Beast’s week-long test, Tom’s Guide’s launch coverage, Furniture Today, Kara Goldin’s founder interview and Design Within Reach product pages. Tiami is new, so customer reviews are limited, and we couldn’t find a Trustpilot profile. Some outlets earn affiliate commissions.
Sleep health note: A single firmness won’t suit everyone. Lighter side sleepers may find a 7/10 mattress too firm at the shoulders and hips. Try Tiami in a DWR store if possible, and consult a doctor if you have back pain. GlossGirly has no commercial relationship with Tiami that affects this verdict.
Full Review Breakdown
Design and Construction
Tiami’s founders chose one mattress instead of a full lineup. Diamonstein told Furniture Today he believes in simple solutions to difficult design problems and didn’t over-engineer the Tiami. The result is a 12-inch hybrid that NapLab says pairs foam layers and free-floating foam cubes with a pocketed coil unit.
The perimeter coils are taller, at 10 inches, to strengthen the edges, per NapLab. The Daily Beast’s tester said the edge support extends usable sleep surface and eliminates the feeling of rolling off, which helped with a partner who sprawls.
Cooling and Motion Isolation
These are Tiami’s standout results. NapLab gave it perfect 10/10 scores for both cooling and motion isolation, well above its averages. The coil unit adds airflow through the mattress, which helps it sleep cool.
For couples, the motion isolation score means one partner’s movement is unlikely to disturb the other. The Daily Beast’s tester said her sleep data improved noticeably after a week.
Comfort, Firmness and Support
NapLab rates Tiami slightly firm at 7 out of 10, with very minimal sinkage of about 1.66 inches. It found the mattress suitable for all sleeping positions and body weights, with strong support.
Because there’s only one firmness, lighter side sleepers should test it first. A firmer feel can create pressure at the shoulders and hips for some people.
Price, Availability and Value
Tiami is priced like a luxury hybrid. NapLab lists a queen at $1,957, while Tom’s Guide reported a queen list price of $2,995 at launch, with sales expected to be rare. DWR has offered discounts, showing a sale range from $1,596 to $2,796 at one point.
Tom’s Guide felt the benefits were less generous than expected for the price. DWR’s 30-day return policy applies to purchases there. Compare terms before buying and check for promotions.
Best Products Worth Buying
Tiami’s flagship and only mattress, a 12-inch hybrid that scored 9.29 overall at NapLab with perfect cooling and motion isolation. It combines foam layers, free-floating foam cubes and pocketed coils with reinforced edges. Best for hot sleepers, couples and anyone who wants a supportive, slightly firm feel. Trade-offs: premium price and only one firmness.
The same design in larger sizes, ideal for couples who benefit most from its perfect motion isolation score. Strong edge support also maximizes usable sleep space. Best for couples with different sleep schedules. Trade-offs: larger sizes push the price higher.
The same mattress sold through DWR, with select stores letting you lie on it before buying. DWR has run periodic discounts and applies its own 30-day return policy. Best for shoppers who want to test in person. Trade-offs: return terms differ from buying direct.
Smaller sizes for guest rooms, teens or single sleepers, with the same construction and cooling performance. Best for anyone wanting luxury quality in a smaller bed. Trade-offs: still premium-priced for smaller sizes.
