Honest Review of the New Tiami Mattress (2025)

It’s always an exciting day when I get to try out a new mattress brand. Tiami comes from the founder of Leesa, bringing some serious credentials—Leesa’s Sapira Chill is our favorite hybrid mattress. Will Tiami be able to live up to its famous sibling? I’m a certified sleep science coach with more than five and a half years of mattress testing experience, and here are my thoughts after a week of sleeping on this bed.

What Makes Tiami Tick

Tiami’s raison d’être is its special features meant to promote better pressure relief and full-body support. However, Tiami is not the first to make this claim. When I initially chatted with Leesa founder and Tiami cofounder David Wolfe, he explained that Tiami’s going after ultra-luxury brands like Hästens, Kluft, and Vispring, which Wolfe says are “great mattresses, but extraordinarily expensive.” (For reference, Hästens’ Vividus model costs $350,000. I’ve never tested a bed of this caliber, but I did once try to visit a Hästens storefront, where I was promptly asked to leave since I didn’t have an appointment.)

Tiami’s hybrid design starts with a 90 percent organic, Oeko-Tex certified organic cotton cover for natural breathability and softness. The brand really hypes up its “Mediterranean-inspired wave design,” a sort of embossed texture on the surface, as a luxury feature. However, I don’t think this matters. You’re going to be throwing a mattress protector and sheets over the bed; you won’t be able to appreciate the Santorini vibes.

The initial memory foam layer underneath uses a proprietary, temperature-responsive foam called Energex, which is supposed to react better to body heat than the usual foams out there to provide pressure relief and bounciness for when you move. Candidly, all memory foam is supposed to absorb heat to do this, but I found the Energex did a good job with these performance aspects—more on that in a minute.

As for the rest of the mattress construction, another memory foam layer underneath helps supplement the Energex. Wolfe told me that instead of using glue, the foam layers are fused and then zoned and ventilated, so you can enjoy the trifecta of softness for pressure points, lumbar support, and airflow. After the foam, we then get to what I consider the star of this particular mattress’s show: the coils. In the Tiami, pocketed coils get an upgrade, too. Each has an Energex foam “cap” to really max out the pressure relief capabilities of this bed.
