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, previously co-founders of Leesa Sleep, according to Furniture Today and BedTimes. Instead of building a large lineup, they created one mattress. Diamonstein, the chief product officer, told press that simplicity is the essence of luxury and that he didn’t over-engineer the Tiami. 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, among the top-rated hybrids 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 of about 1.66 inches, 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 around the perimeter for edge support. NapLab lists a queen at $1,957.
Tiami launched with Design Within Reach as its exclusive retail partner, available in 35 DWR locations, making it DWR’s only third-party branded mattress and its first hybrid. Shoppers can lie on it in select DWR studios before buying. The Daily Beast’s tester said a week on the mattress changed how she sleeps, supported by Oura Ring data, and noted that Architectural Digest named it a Designer Pick. Tom’s Guide reported a queen list price of $2,995 at launch, with sizes from $1,995, and DWR has listed it from $1,995 to $3,495 with periodic discounts.
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 just one firmness, which may not suit every sleeper, especially lighter side sleepers. We couldn’t find a Trustpilot profile, and DWR’s Canadian product page shows a 3.4 out of 5 customer rating, so independent customer feedback remains limited.

Why Trust This Review
This review draws on NapLab’s lab testing, The Daily Beast’s week-long test with Oura Ring data, Tom’s Guide’s launch coverage, Furniture Today and BedTimes reporting, 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 feel extra pressure at the shoulders and hips on a 7/10 mattress. Try Tiami at a DWR studio if possible, and consult a doctor or physical therapist if you have back or joint pain. GlossGirly has no commercial relationship with Tiami that affects this verdict.
Full Review Breakdown
Design and Construction
Tiami’s founders deliberately built one mattress instead of a lineup. Diamonstein told Furniture Today he believes in simple solutions to difficult design problems, and that Tiami wasn’t over-engineered. On Kara Goldin’s podcast, the founders explained their decision to offer one perfected mattress and said this time they weren’t chasing scale.
The result is a 12-inch hybrid. NapLab says it combines poly foam, memory foam and free-floating foam cubes above a 7-inch pocketed coil unit, with taller 10-inch coils around the perimeter. That stronger perimeter improves edge support. The Daily Beast’s tester said it extended the usable sleep surface and eliminated the rolling-off feeling, 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 pulls air through the mattress, which helps it stay cool for hot sleepers.
For couples, a perfect motion isolation score means one partner’s movement is unlikely to disturb the other. The Daily Beast’s tester tracked her sleep with an Oura Ring and said the data showed improvement within a week. Those two strengths make Tiami particularly appealing to couples where one or both partners sleep hot.
Comfort, Firmness and Support
NapLab rates Tiami slightly firm at 7 out of 10, with sinkage of about 1.66 inches versus a 2.18-inch average. It found the mattress suitable for all sleeping positions and body weights, with strong, even support.
Because there’s only one firmness, lighter side sleepers should be cautious. A firmer feel can put pressure on the shoulders and hips for people who don’t sink in much. Tom’s Guide notes Tiami claims its mix of soft, medium and firm materials can suit every sleep style, but testing in person at a DWR studio is the best way to be sure.
Price, Availability and Value
Tiami is priced like a luxury hybrid. NapLab lists a queen at $1,957, while Tom’s Guide reported a $2,995 queen list price at launch and said sales were expected to be rare. DWR has listed Tiami from $1,995 to $3,495, with discounts of 20% or more at times.
Tom’s Guide felt the benefits were less generous than expected for the price, comparing it with Saatva’s Classic. DWR applies its own return policy to purchases there. Compare current trial, delivery and return terms between Tiami.com and DWR before buying, and watch 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 layers poly foam, memory foam and free-floating foam cubes over pocketed coils, with taller perimeter coils for edge support. NapLab found it suits all sleep positions and body weights. Best for hot sleepers, couples and anyone who wants a supportive, slightly firm feel. Trade-offs: premium price, a single firmness and limited long-term owner reviews.
The same design in larger sizes, ideal for couples who benefit most from its perfect motion isolation score. The reinforced edges also maximize usable sleep space, so you can sleep near the edge without feeling like you’ll roll off. Best for couples with different schedules or restless partners. Trade-offs: larger sizes push the price well above typical hybrids.
The same mattress sold through DWR, Tiami’s exclusive retail partner, with select studios letting you lie on it first. DWR has run periodic discounts on Tiami. Best for shoppers who want to test in person and pair the mattress with DWR furniture. Trade-offs: DWR’s return terms may differ from buying direct, so confirm before ordering.
Smaller sizes for guest rooms, single sleepers and apartments, with the same construction and cooling. They bring luxury hybrid performance to a smaller footprint. Best for anyone who wants top-tier comfort in a smaller bed. Trade-offs: still premium-priced for the size.
What Customers Actually Think
Note: Tiami is new and has very few independent customer reviews, and we couldn’t find a Trustpilot profile. The statements below come from testers, press and the founders, clearly attributed.
“delivers fantastic performance overall” — NapLab (Tiami Hybrid)
“A week on this ultra-luxe hybrid mattress changed the way I sleep” — The Daily Beast tester (Tiami Hybrid)
“For the premium price tag we might have expected better benefits from Tiami.” — Tom’s Guide (Tiami launch coverage)
“That’s why we didn’t over-engineer the Tiami mattress.” — Jamie Diamonstein, Tiami co-founder, via Furniture Today
3.4 out of 5 customer rating — Design Within Reach Canada product page
Is It Worth It?
Yes, for hot sleepers, couples and design-focused buyers who want top-tier cooling and motion isolation from an experienced team. Lighter side sleepers and budget shoppers should test it at a DWR studio first and compare prices across Tiami.com and DWR.

Final Verdict
Tiami is what happens when an experienced mattress team starts fresh with one goal: build a single, refined luxury hybrid. NapLab’s testing supports that ambition, with a 9.29 overall score and perfect marks for cooling and motion isolation, plus support that works across sleep positions and body weights. The Daily Beast’s tester saw measurable sleep improvements, and the Design Within Reach partnership adds design credibility along with the rare chance to try a premium online mattress in person.
The trade-offs are price, a single firmness and limited owner feedback. NapLab notes Tiami costs well above the average hybrid, Tom’s Guide expected more generous perks, and lighter side sleepers may find it too firm. With few customer reviews and no Trustpilot profile yet, long-term durability is still unproven. Test it at a DWR studio if you can, compare terms between Tiami and DWR, and buy during a promotion. For hot sleepers and couples who want a design-forward luxury hybrid, Tiami is one of the most compelling new mattresses available.
