NPS 3200 Series has brought the potential comfort of folding chair to a whole new level with a super-soft 2 inch thick cushion. Features include an institutional-grade vinyl upholstered box seat on a Masonite board. The large contoured padded backrests are fully covered in matching vinyl on both sides. The institutional-grade frame is made from heavy-duty powder-coated 18-gauge round tubing with two U-shaped double-riveted cross-braces - one in front and one in the back - to securely support the double-hinged legs. Color-coordinated V-tip stability plugs provide added reinforcement at the frame's junction and matching replaceable glides prevent floor damage.
