Abstract
In the case of an item of seating furniture, particularly an office chair, comprising at least one seat adjusting device, for example for adjusting the height of the seat, with a spring element engaging the two parts of the seat which are to be adjusted in respect of each other, particularly a pressurized fluid filled spring, and with a locking device for the separable fixing of the two seat parts in whatever is the desired and selected adjusted position, the use of an electrical actuating element for the locking device is proposed, which is connected to a manually operable control means for the at least one seat adjustment, this allowing simplified operation with minimal structural expenditure.
