(under subclass 690) Mattress adapted to be converted to a device other than a mattress (e.g., usually another body supporting device such as a seat, chair, foot support, exercising device, bathing device, or the like).
(1) Note. The mattresses in this subclass may be converted to other devices by repositioning or rearranging portions of the mattress relative to each other, possibly with adding additional structural elements to accomplish the conversion to the new device.
(2) Note. Excluded from this subclass are mattresses that have sections that are connected or connectable to each other in a manner to permit the folding or stacking of the sections in order to save on the storage space needed or to facilitate transportation.
