NIAGARA is Furniture49’s premiere seating option for the progressive and robust classroom line. No structural ribs, no unsightly lines, substantial construction with no voids or cavities. Pure elegance in a myriad of models are available: Cantilever, four-leg, caster, swivel stool, task chair and lab stool. Shells are created from heavy duty and static free, high-density polypropylene material with a light grain texture surface on both sides which is injection molded into a one-piece shell with waterfall edge. The ribless back design provides comfort and flexibility and the ergonomically designed opening in the shell back provides added comfort as well as a handle grip. The shell is attached to the frame with steel rivets underneath the seat, which offers no exposed hardware on the surface. Legs are formed of tubular steel and the frame is bright nickel chrome.
