Strong as an elephant and quiet as a mouse! The gorgeous 6600 Series Elephant Z-Stool with Backrest is the zenith of ergonomic design and stylish comfort, perfect for hands-on settings like art studios or science labs. The mammoth, chrome-plated, 12-gauge, oval tubular steel frame is available in three separate height options. Footrest has a smooth-textured surface for traction and rear brace for extra stability. Each stool features a black, lightweight, blow-molded, polypropylene seat and ventilated fan-backed backrest, contoured to fit the user. Sturdy, U-shaped, sled-base legs distribute weight across a wider surface, minimizing pressure on floors. The glides are securely bonded with thermoplastic polyurethane (TPU) and move softly over any surface. Z-Stools are conveniently stackable (six units high) or hang with ease from tabletop surfaces, allowing for simple clean-up and storage.
