How It Works

Chilipad removes heat from your sleep surface. No magic, just physics.

It’s Thermodynamics, without the textbook. Your body gives off heat. Water picks it up. The Dock moves it out. You sleep cooler.

Three parts. One seriously cool system.

Not three separate gadgets — one closed loop. The Dock, Chilipad, and Remote work together to move heat away from your body and keep your bed at your ideal temperature.

How Chilipad 2.0 Works

Fill the water reservoir.

The Dock chills the water before it reaches your bed.

Cold water flows through the Hydrolayer to absorb body heat.

The warmed water flows back to be cooled again.

The Dock moves out heat.

The system keeps your ideal temperature steady all night long.

Nature already engineered a pretty great cooling system. We put it in your bed. Water is up to 25 times more efficient than air cooling.

Simple idea. Serious engineering.

Water is up to 25x more efficient than air cooling

Water moves heat far better than air — the same reason a cold plunge cools you faster than standing in front of a fan. The Dock uses solid-state thermoelectric cooling (Peltier), a whisper-quiet pump, and an acoustically tuned fan. No compressors. No chemical refrigerants.

Clinically-backed sleep science. Felt every night.
