In a rotate and tilt arrangement for a CRT display, a display enclosure has a base with a spherical surface which normally rests on a rubber ring mounted on a support surface. This is a locked position maintained by friction between the spherical surface and the rubber ring. A PTFE ring is positioned in a slot around the upper surface of the rubber ring. The rubber ring is made pneumatic by an enclosed air space around the ring. A diaphragm pad in communication with the air space enables air to be forced into the air space to inflate the rubber ring and lift the PTFE ring to project above the rubber ring. In this inflated position the spherical surface rests on low friction PTFE and so the display may be rotated and tilted as desired. Fig.
