description A linear drive to drive an article of furniture includes at least one drive motor that is coupled with a linearly moveable driven member and a braking system with a controlled braking element which commences the braking function without delay. The braking system can have a small footprint. According to the invention, the drive for the article of furniture can include an actuator, such as a piezo actuator coupled directly or indirectly with the braking element acting on the rotor shaft of the drive motor. The piezo actuator is preferably connected to the electric terminals of the drive motor. The linear drive can be used to adjust the support for a lath bed or a chair.
