The ColdBed Water Pillow™

the first ever ultra high cooling capacity pillow

The Water Pillow™ offers 21,000 cubic centimeters of water-filled cooling capacity, providing 100x the heat sinking capacity of a standard pillow.

The Water Pillow is designed for humans

Run The Numbers

Large mattress toppers with pumped water have ~25% efficient coolers that increase your electricity bill, and heat your room to try to handle cooling with a single millimeter of water. Plus, the stiff, PVC tubes are far less comfortable than your mattress.Our solution leverages physics, using water to give the Water Pillow much more passive cooling capacity than an active topper (if you combine with the included under pillow massive ice pack) and applies cooling where it matters most.

Cold Bed, Coldest Pillow

Cold Sleep = Best Sleep

research proves getting cold at night is critical to optimal health, performance, and recovery


Head + Neck = Heat Sink

with ample blood flow, Pillow by ColdBed draws heat from where your body is best at cooling off


Water Cooling, Gel Comfort

the gel grid provides soft mechanical support so you don't feel like your head is on a rigid water bag

Do you want to achieve peak human?

We evolved in the cold

Excessively hot indoor environments make you weak. Your metabolism fails, you get fat, and your body is unable to run all its amazing biochemical processes the way it wants to. Imagine how angry a chemistry lab tech would be if you broke into their lab and turned off all their fridges and freezers... but you'll do that to your own body?

The first major sleep innovation in years

Water Pillow™ by ColdBed

The ColdBed Water Pillow is easy to fill and empty as needed. A soft gel grid supports your head while the water provides way more cooling than air or gel alone ever will. Operates silently, with no pumps, valves, or WiFi connections that can break.
