The frame carrier having at least one dome-shaped rolling body (3, 8) which rolls along a pressure-resistant rolling plate (2) in the X- and Y-direction, and two cylinders (6, 7) which slide one into the other and are supported against each other in the Z-direction by a compression spring (4). One of the cylinders (7) which slide one into the other being connected in a spring-loaded and hinged manner to the frame (18) of the couch or seat via a frame connection plate (13).
