Artco-Bell's Discover Series Adjustable-Height Lab Stool features a solid polypropylene chair shell with an ergonomic design, offering proper support and relief on pressure points. The flexible back and waterfall edge lend a touch of modern design, and the easy lever adjustment lets you set the chair at a comfortable height. The heavy-gauge steel frame endures years of lab use, and the fixed foot ring offers added comfort. A built-in hand hold in the back of the chair and five swivel casters make movement around the classroom simple. Available in a variety of colors. Choose from several seat sizes.
