how?

Chairs control the collapse of the spine that occurs in sitting.

The back support of the chair pushes the spine forwards to reposition the upper body over the seat.

If the chair supports the balance point (keystone) of the mobile part of the spine correctly, the ribcage and head will reposition over the pelvis: good posture.

Using a single moveable cushion to support the keystone of the each user in sitting, the body is held in line with gravity, reducing joint and muscle strain.

The elegant and minimalist design can be customised to each user, improving comfort, flexibility and function.
