Abstract
A self-adjusting furniture glide includes an upper body piece rotatably mounted to a lower foot piece having an arcuate ramp surface on which a complimentary ramp surface of the body piece rests, and a coil spring mounted between the foot and body pieces to downwardly bias the foot pieces and to apply a torque which opposes mutual rotation of the pieces.
