Tiami, a new luxury mattress brand from sleep veterans Jamie Diamonstein and David Wolfe, has officially launched with an exclusive partnership at Design Within Reach (DWR). Available now at DWR.com and Tiami.com—with select DWR showrooms stocking the hybrid mattress in June—Tiami aims to solve common sleep woes like aches, overheating and restless partners with one versatile design.
Handcrafted in the U.S., the Tiami mattress marries an open-cell Energex comfort layer for cooling responsiveness with a high-performance memory foam recovery layer to ease pain and support spinal alignment. A double-pocketed coil base and Energex pods adapt to body shape and limit motion transfer, while reinforced perimeter coils deliver firm edge support and a roll-off-free sleep surface. By blending plush, medium and firm feels into one system, Tiami wants to eliminate the need for multiple firmness options under the same roof.
“Two years after selling our last venture, we’re not chasing scale; we’re focused on refinement,” said CEO David Wolfe. Co-founder and chief product officer Jamie Diamonstein added, “Simplicity is the very essence of luxury. We fine-tuned each component so the mattress works seamlessly without over-engineering.”
Priced at $3,000 for a queen, Tiami also marks DWR’s first third-party mattress partner and only hybrid offering, reflecting a shared dedication to modern design and craftsmanship. The founders plan to reinvest part of future revenue into sleep equity programs supporting mental health for young mothers, continuing their legacy of impact alongside innovation.
