Abstract
A furniture member has a base frame including first and second frame members each having a first or second frame support tube. A mechanism includes a motor connected to the base frame and a torque tube connected to first and second support brackets and the motor. A stiffening tube assembly has first and second side stiffening tubes, the first frame support tube connected to the first side stiffening tube and the second frame support tube connected to the second side stiffening tube. Multiple rotation links include a first set connected to the first frame support tube and the first side stiffening tube, and a second set connected to the second frame support tube and the second side stiffening tube. The rotation links allow mechanism rotation to a forward lift position by motor operation displacing the torque tube and thereby forwardly rotating and lifting the side stiffening tubes.
