A support plate for receiving the upper back portion of a user is fixedly secured to the rod, while a lower support plate is interconnected with the upper support plate through a universal joint which may be selectively locked into position or released to allow the lower support plate to swivel with respect to the upper plate. An appropriate gear reducer is connected to the rod to allow the rod to be rotated to position the user in a desired orientation.
