Abstract: A play system floor includes a frame defining the periphery of an area to be floored and a webbed flooring constructed of a webbing material extending between the frame members. The webbing material has an optimal predetermined stretch coefficient at which it retains its resiliency, while resisting sagging. The webbed flooring is sized using the stretch coefficient whereby the dimensions of the webbed flooring when stretched substantially correspond to the dimensions of the area to be floored. The webbed flooring is stretched to the dimensions of the area to be floored and secured to the frame. The floor is stretched to the dimensions of the area to be floored by positioning a bar through loops on each side of the weaved flooring, and applying tension to each bar. The webbed flooring is secured to the frame by attaching each bar to the frame using clamps, bands, or other attaching devices. Tension to each bar is applied by operating a screw-actuated clamping member to tighten the bar against the frame.
