A staple of libraries for the last half-century, this versatile rolling Step Stool has been updated in plastic to be lighter and more dent resistant than earlier metal versions. Sitting on retractable casters that lock in place when weight is applied, this Stool provides two extra steps – or even a seat – where needed, in a size that’s much more convenient than a ladder. The wrap-around rubber bumper protects walls and furniture, and the textured tread helps prevent slipping, even in damp areas like kitchens and bathrooms. Whether used at home, in the garage or in the workspace, when something is this functional is it any wonder it has been around for 50 years?
