MEDesign Backfriend

Backache during and after sitting afflicts millions of people worldwide. Many of them are healthy individuals who just find sitting uncomfortable, others are already being treated for their back pain.

Much of the pain and discomfort is due to poor seat design but it also depends on what you are doing: Your angle of vision, the load in your hands and on your shoulders can all lead to postural stress on the back. For this reason, no single seat or chair design may be exactly right.

To prevent backache, a backrest should take the weight off your spine up to mid shoulder level; the curves of the low back support must fit you properly and prevent your pelvis from rolling back; and the inclination of the backrest must be adjustable.
