Your bed, your temperature. Every night.

Good to know.
The most common questions, answered briefly and honestly.
Can each side have a different temperature?
Yes. The device has two separate controls – one for each side of the bed. So everyone sleeps exactly the way they like.
Do I need an app or a subscription?
No. You operate Alpine Sleep directly on the device. No subscription, no hidden costs.
Will the topper fit my mattress?
Alpine Sleep is available in 160 × 200 cm and 180 × 200 cm. The topper is pulled over the mattress like a fitted sheet, your bed sheet goes on top.
How often do I need to refill the water?
The tank holds about 900 ml. Check the water level regularly and top up as needed.
How much electricity does Alpine Sleep use?
Max. 400 W when cooling and 800 W when heating. Because only the bed is heated or cooled instead of the whole room, it is often more economical than an air conditioner or room heater.
Where do I put the device?
On the floor next to the bed, with some distance from the wall so air can circulate. The hoses run under the bed sheet to the topper.
