This invention provides in an article of manufacture having a fabric support surface: a fabric support surface; a peripheral frame for the support surface, said frame having opposed base sections and opposed flexible arch sections extending between the base sections; and arch flexing means for moving the opposed base sections towards each other to flex the arch sections outwardly of each other and for maintaining the base sections from separation whereby to tension the fabric support surface between the arch sections and form a firm support for weight placed thereon and to restrain the effect of weight thereon from moving the opposed arch sections inwardly of each other.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:] [1.]1. An article of manufacture comprising;a fabric support surface;a peripheral frame for the fabric support surface, said frame having opposed base sections and opposed flexible arch sections extending between the base sections, the arch sections being responsive to movement of the base sections towards each other to flex the arch sections outwardly of each other and responsive to movement of the base sections away from each other to flex the arch sections inwardly of each other, said frame being secured to sad support surface along its flexible arch sections, and said fabric support surface having arch flexing means extending between and around the opposed base sections for controlling the position of the opposed base sections relative to each other to flex the arch sections outwardly of each other a distance to tension the fabric support surface between the arch sections to form a support for a weight placed thereon in use when the arch flexing means is tightened and for maintaining the base sections from separation to maintain the arch sections outwardly flexed of each other and to transmit the force of load on the fabric support surface transmitted to the arch members in use, from the arch sections, through the base sections to the arch flexing means.
