ABSTRACT:
A device for positioning between a box spring and a mattress for selectively raising at least a portion of the mattress has a base frame secured to the box spring or box spring frame. A mattress supporting frame is pivotally coupled to the base frame. A leveraging arm with a roller bearing is pivotally coupled to the base frame. A linear actuator having a electric motor and a displaceable shaft is pivotally coupled to the leveraging arm and extension of the shaft pivots the leveraging arm upwardly, raising the roller bearing against a cross member of the mattress supporting frame to lift a portion of the mattress. Mattress restraining members prevent the mattress from shifting as the mattress is raised. The base frame is adapted to nest within the mattress supporting frame when the device is in a lowered position to minimize the vertical space required for the device.
