Abstract
Abstract The present invention relates to a bolster which is used for physical therapy especially for handicapped children. The bolster comprises a pair of solid discs at the ends thereof and a plurality of spaced, hollowed-out intermediate discs having a cylindrical outer shell preferably of relatively light gauge metal wrapped thereabout. The cylindrical shell is then covered with a layer of foam rubber which is adhered thereto and turned over onto the periphery of the end discs. A brightly colored vinyl covering is then placed over the foam rubber. The operation may be facilitated by covering the foam rubber first with a plastic sheet or other low friction thin covering and slipping the vinyl thereover. The vinyl covering is secured in place to the end discs and a handle is fastened to one of the end discs for ease of handling. The resulting product is extremely sturdy, durable and light weight as well as being relatively inexpensive thus facilitating its use by handicapped individuals in physical therapy applications.
