Abstract
Abstract Support pads or mattresses are formed from flexible fabric closed covers of generally rectangular configuration forming a chamber or space which is filled to approximately 50% of its normal maximum volume with relatively small expanded polystyrene beads. In one embodiment the pad is formed with intersecting disconnectable straps for restraining an infant in a generally reclined position on the pad. The pad may be converted for use as a carrying bag or container by forming a cavity or receptacle in one end of the cover by displacing the flowable polystyrene beads and utilizing one of the straps as a carrying strap for the bag, thereby providing a protective insulated carrier for various articles. One embodiment of the pad includes a segmented fabric cover forming a plurality of pockets for receiving individual pads or cushions whereby the pad may be utilized as a lounging mattress, swimming pool float, chair, or bench seat. Each of the individual cushions may be removed from the segmented cover for distribution and use in supporting various parts of the human body.
