In an item of furniture having a movable furniture part, such as a drawer, door or folding part, a damping apparatus damps movement of the movable furniture part. The damping apparatus is constructed as a negative-pressure damping apparatus or combined pressurized and negative-pressure damping apparatus. It has a piston (3) and a resiliently deformable piston part (6) in the piston rod (4). This resiliently deformable piston part (6) is pressed against the cylinder wall during the damping procedure.
