Rock-Rock / Chair


Rock-Rock can detect the sitting posture of elder continuously. It can change the angle and reduce the stress onto the body by swinging, preventing elders from hardening into stone, poor blood circulation and being numb. With Rock-Rock, they can sit more cozy and safer.

When you stay in the same pose over 20 minutes, Rock-Rock will swing slowly to change the angle. Different positions of chair lead to different sitting postures, so your posture will then change as well.

Rock-Rock has small raised balls on the surface detecting the posture of the user. The chairlegs have a gyroscope to duly swing at an angle.
