Tiami: One Carefully Engineered Luxury Mattress From Leesa’s Founders

Tiami’s documented strength is performance in testing. The brand was launched by Jamie Diamonstein and David Wolfe, previous co-founders of Leesa Sleep, with an exclusive retail partnership with Design Within Reach. NapLab scored the Tiami 9.29, placing it in the top 6% of hybrids it has tested. NapLab rated its cooling and lying edge support as outstanding, its support as outstanding and its pressure relief as excellent. The Daily Beast’s tester said a week on the mattress changed how they sleep, backed by Oura Ring sleep data, and noted Architectural Digest named it a Designer Pick. Cool Material’s reviewer, after a full year, called it one of the best home upgrades they’ve made, saying they no longer wake up sweaty or achy. Tom’s Guide named it an Editor’s Pick, according to Tiami.

Tiami sells just one mattress: a 12-inch hybrid built with poly foam, memory foam and pocketed coils, topped by free-floating foam cubes that sit above the coils to create a “floating” feel. NapLab rates it slightly firm, about 7 out of 10, with reinforced perimeter coils. Tom’s Guide reports prices starting at $1,995, with a queen at $2,995, and says Tiami has implied sales will be rare. It’s made in the USA from globally sourced materials and comes with a 100-night trial and a 10-year limited warranty, according to Design Within Reach. You can try it at select Design Within Reach showrooms, and Tiami says a portion of future revenue will support sleep equity programs focused on mental health among young mothers.

The honest caveat: Tiami is expensive, with policies that are only average for its price. Tom’s Guide notes competitors like Saatva offer a 365-night trial, a lifetime warranty and free white-glove delivery for less. NapLab reported a strong smell on unboxing and limited bounce. As a new brand, Tiami has little independent customer feedback. Its own site shows 5.0 from just 15 verified reviews, while a Design Within Reach Canada listing shows 3.4.

Why Trust This Review

This review draws on NapLab’s objective testing, hands-on reviews from The Daily Beast and Cool Material, Tom’s Guide’s launch coverage, trade reports from Modern Retail, BedTimes and Furniture Today, and Tiami and Design Within Reach product information. Some testers may have received free mattresses. We couldn’t access a Trustpilot profile for Tiami, and on-site reviews are brand-curated.

Full Review Breakdown

Design and Construction

Tiami takes a deliberately simple approach: one mattress, engineered carefully. Co-founder Jamie Diamonstein describes it as the most advanced mattress he’s created and, in many ways, the simplest. The 12-inch hybrid uses poly foam, memory foam and pocketed coils, with free-floating foam cubes placed above the coils, according to NapLab. Those cubes let each area respond independently, which testers say creates a floating feel and strong pressure relief. Reinforced perimeter coils boost edge support. The flat-top design is intended to look clean and modern in a well-designed bedroom, which explains the Design Within Reach partnership. Cool Material’s reviewer said it elevates the whole room. Tiami says it’s made in the USA.

Comfort and Support

NapLab rates the Tiami slightly firm, about 7 out of 10, but notes the feel is complex. It scored support as outstanding and pressure relief as excellent, making it suitable for many sleeping positions. Cool Material’s reviewer, mostly a side sleeper who moves around, said it feels supportive yet comfortable however they end up, and that they no longer wake achy. The Daily Beast’s tester credited it with measurably better sleep. One YouTube viewer described near-zero pushback and noticeable sinking around the hips, with a slow-responding surface similar to memory foam. NapLab also notes limited bounce, which some combination sleepers or couples may notice.

Cooling and Edge Support

Cooling is one of Tiami’s strongest results. NapLab rated it outstanding, and Cool Material’s reviewer said their old mattress held heat but they stopped waking up sweaty on the Tiami, even in a warm room. Edge support is another highlight. NapLab rated lying edge support outstanding and sitting edge support good, thanks to reinforced perimeter coils. The Daily Beast’s tester said it expands the usable sleeping surface and eliminates the roll-off feeling. NapLab did report a strong smell on unboxing. Let the mattress air out for a day or two before sleeping on it.

Price, Policies and Value

Tiami is a luxury purchase. Tom’s Guide reports a starting price of $1,995, with a queen at $2,995, and notes Tiami has suggested sales will be rare. Its 100-night trial and 10-year limited warranty are industry-average, which Tom’s Guide contrasts with Saatva’s 365-night trial, lifetime warranty and free white-glove delivery at a lower queen price. Delivery is free, according to Tiami. Buying through Design Within Reach may come with different terms, so confirm return policies with whichever retailer you use. For value, Tiami is best suited to buyers who prioritize top-tier testing results, cooling and design, and can try it in a showroom first.

Is It Worth It?

Yes, for hot sleepers and design-focused buyers who want top-tier testing performance and can afford about $3,000 for a queen. Try it at a Design Within Reach showroom first if you can, and compare policies with competitors like Saatva.
