Claim:
1. A kit for constructing a support surface for a sleeping person, said kit comprising: an air-permeable layer having at least one pair of opposing layer-edge portions stretchable at least in the direction between said layer-edge portions to form said support surface; at least one pair of substantially parallel opposing frame sections fixedly disposable at a distance therebetween for forming at least a portion of a frame supporting said support surface, at least a first frame section of said frame sections comprising a layer-edge engaging portion configured for fixedly engaging a corresponding layer-edge portion; and at least one pair of opposing corner elements; wherein said first frame section is pivotally mountable between said corner elements for pivoting at least from a pre-tensioned position in which said layer-edge engaging portion and said corresponding layer-edge portion are spaced from the opposition frame section to a first distance, to a tensioned position in which said layer-edge engaging portion and said corresponding layer-edge portion are spaced from said opposition frame section to a second distance which is shorter than said first distance, so as to at least partially tension said air-permeable layer between said frame sections.
