These stools, and benches, were the result of a one week course in furniture design at the school of architecture. In the 90-ties I produced about 20 of these stools on my own and they were sold in design-shops, among them Plan 1. A few bar-stools were used in the furnishing of the Globe Hotel in Stockholm.
The comfortable seats of these stools are based on a frame with a seat composed of wooden balls. The balls, dependent on the pressure of the body on the seat, and relatively independently of each other, sink into an elastic material. Thus active sitting will stimulate the circulation of the blood – an effect which has however not yet been medically tested.
