A flat lifting element that is configured as a drive system for use in furniture is intended to be so simple, from the design standpoint, that it is extremely compact, can support relatively heavy loads, and can be used universally. According to the present invention, the flat lifting element (10) comprises an outside and an inside hollow-profile support (11, 12) that are of enclosed cross-section. The width of these is significantly greater than the thickness. In addition, it comprises an electric-motor adjuster system, the linearly movable driven member of which is coupled to the outside or to the inside hollow-profile support (11, 12). The surfaces of the outside and the inside hollow-profile supports (11, 12) that face each other can be provided with profile cross-sections that fit inside each other and extend in the direction of movement of the extendable hollow- profile support (11 or 12). The flat lifting element according to the present invention is particularly suitable for furniture drive systems.
