Quiet and maintenance-free
A new therapeutic seating concept is presented here. The seat is intended to influence the user's behavior. The “Wippsi” can be adjusted so that it can be used for children and adults. Bearings with a low thickness were necessary for the design that are also maintenance-free and quiet. The igus® plain bearings installed were able to fulfill these demands without any problem. The drylin® N rails provide a high sliding ability at the same time as torque resistance for the height adjustment on the seat.
