Claim 1
Independent Claim
414 words
A portable lounging apparatus comprising: A single, integral, thin rectangular sheet of resilient foam material having a sufficient firmness that when it is spread out it provides a comfortable support on a floor for a human body lying thereon, said integral resilient foam material sheet being sufficiently resilient that it can be easily folded into a roll for carrying and handling, being sufficiently flexible that it is not damaged by repeated folding and unfolding thereof, being sufficiently strong that the previously mentioned activities do not cause disintegration of it over a long period of use and being of such a size as to hold a human body thereon; a cloth container having a size and shape approximately the same as that of said single, integral, thin rectangular sheet of resilient foam material for snugly enclosing said sheet of resilient material therein, said cloth container having a foot-end edge, a head-end edge, and two side edges, one of said head-end edge or a side edge of said cloth container having an opening therein through which said sheet of resilient foam material can be selectively inserted into said cloth container and removed therefrom, said cloth container including a closure means for selectively opening and closing said opening, the foot-end edge of said cloth container and the other of said side and head edges being permanently closed, said cloth container being constructed of a durable cloth material; and, a rectangularly-shaped cloth cover sheet having a foot-end edge and a head-end edge, said cover sheet being substantially wider than the fully-extended width of said cloth container, the foot-end edge of said cover sheet however being permanently sewn by a seam to the foot end edge of said cloth container with the sides of said cover sheet extending substantially laterally beyond the side edges of said cloth container but not being attached to said side edges, the foot-end edge of said cover sheet being gathered to make the size of the foot-end edge of said cover sheet approximately match that of the fully-extended foot-end edge of said cloth container said gathered portions being permanently sewn by said seam to the foot end edge of the cloth container along with the rest of said foot-end edge of said cover sheet, the two side edges of said cloth container remaining substantially unattached to any sheets, said cover sheet being constructed of softer material than the cloth container and having a length for substantially covering a person lying on said cloth container.
