Abstract: An automatic height and angle adjusting swivel glide for use on furniture, such as tables, chairs, etc., or other equipment, having an upper and a lower shell or housing part secured together, a multisectioned collet within the assembled shells resiliently held together by means of an elastic ring, and a cam with a stem for securing to the furniture or equipment. The collet is provided with opposed concave generally conical surfaces receiving a cam surface on the lower end of the stem and a second cam surface on the raised central portion of the lower floor-engaging shell. Interaction between the cam surfaces and the collet allows the glide to rise, lower and tilt relative to the stem and compensate for irregularities of the floor surface.
