No weeks away

Serious athletes go away to altitude camp for weeks. The Sleep Cloud brings altitude home, so you train as normal, have dinner with the family and go to bed at altitude.

Your own bedroom, at altitude

The Sleep Cloud canopy stands over your Queen or King bed. An F10 or F20 altitude generator supplies the air and you set the altitude in the app. The Box Altitude Sensor inside checks it all night.

How loud is it?

About 31 dB at the pillow, with the altitude generator placed away from the bed.

How does set-up work?

Your bed stays where it is and the frame goes up around it. The generator can sit outside the bedroom, with the air piped in. Then you pair it with the Box Altitude PRO app and set your altitude.

Who is it for?

Endurance athletes who take their training seriously, from age groupers to pros. We'll tell you on the call if it's the right fit.
