A series of plywood slats cut at a slight angle give the seat a graceful curve when compressed, and alternating recesses at the edges keep fingers from getting caught. A sheet of spring steel, so thin it almost vanishes, works with the plywood to support up to 600 lbs. If overloaded, it bends and stretches instead of snapping, making it far safer than a folding chair. The high-density foam cushion provides seated comfort, yet allows the entire seat to fold to a flat 4” slab, keeping walkways passable for audience members, and taking up astonishingly little space when stacked for storage.
