Kick it and it rolls. Step on it and it stays. This compact, lightweight stool rolls where you need it and then the casters underneath retract to a non-skid bumper when you step on it. The bumper is a wraparound style which will protect furniture and walls from nicks and scratches. These stools support up to 300 lbs. and were designed for a lifetime of dependable use. There are four available colors: red - #419680, black – #419681, green – #419682, and blue – #419683.
