A bedding foundation has a linear actuator for moving a roller carriage forward and backwards. The roller carriage includes wheels which move along rails supported below a rigid platform having an opening extending through the platform. The roller carriage includes a lifter which raises and lowers a roller independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the roller may be raised or lowered. The roller moves back and forth inside the opening extending through the rigid platform and imparts a massage movement to a mattress above the foundation.

A bedding foundation has a linear actuator for moving a first pin forward and backwards. The first pin moves along linear slots extending through side rails of a rectangular frame. The foundation includes a lever which raises and lowers a plate independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the plate may be raised or lowered. Movement of the plate imparts a massage movement to a mattress above the foundation.

A bedding foundation has a motorized linear actuator for moving a carriage forward and backwards. The carriage includes wheels which move along side rails of a frame. A rigid platform having an opening extending through the platform is secured to the frame. The carriage includes a lift motor assembly which raises and lowers a massager independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the massager may be raised or lowered. The massager moves back and forth inside the opening extending through the rigid platform and imparts a massage movement to a mattress above the foundation.
