The surface has an electro-mechanic lifting unit (20) for lifting and lowering one of bars (22) relative to a bearing element of the bar. The lifting unit includes housing with an electromotor having a drive shaft, a transmission and a lifting member supported at the bearing element of the bar. A vibration-damping support of the electromotor in the housing is formed by an air cushion or elastomer material. The bearing element at which the lifting member is supported is attached to a frame portion (66) of a mattress, where the frame portion is mechanically decoupled from the bearing element. |
