Water-Circulation Sleep Climate
A mattress pad that cools and heats each side independently — so neither of you has to compromise on the temperature of the night.
Why Temperature
The link between temperature and sleep is established sleep science. What we build is a precise way to act on it.
Dual-Zone Control
Water circulates through two independent loops inside the pad. Each side gets its own target temperature — set it once, and the night takes care of itself.
One pad, two climate loops. Change your side without touching theirs.
Cools in summer, warms in winter. Fine-grained targets instead of “low / medium / high”.
A closed water loop carries warmth away or back — no fan blowing at your face.
Reach for the bedside hub at 3 a.m., or fine-tune from the app — both stay consistent.
The System
No compressor humming on your nightstand, no air vents under your pillow. Just water, moving silently between the hub and the pad.
The bedside unit cools or heats water to your target and keeps two loops at their own temperatures.
A slim pad on top of your mattress, with soft micro-channels that spread the temperature evenly across each zone.
Set targets, schedule the whole night, and wake up to a report of how it went — from your phone.
Illustrative target schedule — targets you set, not measured bed temperature. Cooling to settle, steady through the night, gently warmer toward morning.
The App
Real control of both zones from your phone — and a morning report that explains the night in plain language.
