Abstract
An oscillating device comprises a body support on which opposed open bearings are located, the bearings are compliant and have self-lubricating bearing members secured therein so that bearing-engaging sections of legs that are pivotally mounted onto a base are disposed in the bearings in engagement with the self-lubricating bearing members and springs are mounted on spring-engaging members on arms of the legs to maintain the legs in a substantially vertical rest position and to move the body support along an arcuate path when it is moved from the vertical position in an oscillating motion.
