This beam seating is designed specifically for use in high traffic, institutional environments like waiting rooms, lobbies, dayrooms, visitation and intake areas. Manufactured to survive the rigors of continuous institutional use - and looks great doing it. Roomy ergonomic seats, they are a comfortable full 20" wide. Seats are rotationally molded from durable poly-ethylene - fire-retardant, non-absorbent and easy to clean. Molded-in threaded steel inserts provide for tamper-resistant, " steel-to-steel" attachment to the base frame.
