Abstract: A rotating positioning platform apparatus for providing stimultion to a client population consisting of non-ambulatory persons having a mental age in the range of zero to five years. The apparatus consists of a rotating platform having a mattress therein and a bolster mounted on the periphery thereof to permit one or more of said persons to be placed and remain comfortable. A pole and canopy is mounted above said rotating platform. Under the canopy there are formed a number of quadrants each one of which is provided with a source of stimulation such as feel, sight, and sound. As the platform is rotated the person thereon is subject to each different kind of stimuli in sequence when the pole is stationary.
