Remster

Remster is a temperature-controlled sleep system built around a nightstand tower, a fitted bed cover, and cervical pillows that together regulate four separate zones across the head, neck, core, and feet. Each side of the bed runs independently, so two sleepers with different temperature preferences can share the same mattress. The launch matters because most smart-bed products on the market cool or warm a single surface uniformly, while Remster is targeting the more granular thermal physiology that governs how quickly you fall asleep and how deeply you stay there. The underlying idea is distal vasodilation, the process by which warming the extremities pulls heat away from the core and triggers sleep onset. Remster leans on a peer-reviewed proof-of-concept study by Haghayegh and colleagues that tested a mattress with a cool center, warm edges, and mild neck warming, and it uses those findings to drive its zone setpoints. A sensor is woven into the cover itself, so heart rate, breathing, and movement are tracked per sleeper without a wearable, and the system can also shift bedtime and wake time the night before an early flight or meeting when synced to a calendar. The company is led by co-founders Sumukha Nadig, who previously completed an MS by research in aerodynamics at IIT Madras, and Shubham Gupta, and is backed by F.Inc. Remster is opening pre-orders with a $199 deposit ahead of a bundle that includes the nightstand, the four-zone cover, and two temperature-controlled cervical pillows, aimed squarely at operators, athletes, and executives who already treat sleep as a performance input.
