Abstract
A position programmable adjustable chair particularly useful in dental and medical procedures. The chair is hydraulically powered and controlled by microprocessors which enable chair seat and back positions to be memorized and automatically captured upon command by use of a single control button. The control button may be located either on the chair or on a footswitch. A sealed omnidirectionally operable footswitch is provided which is particularly suited for use in combination with the chair.
