There are times when working on your vehicle — from cleaning it to changing the tires — that you need an adjustable-height stool that also doesn’t take up valuable garage space when not in use. The Portable Telescoping Stool from Steel Vision Tools is one option. The base can be locked in 11 different positions (up to 18 inches high) and the 11-inch diameter seat also serves as the stool’s storage case (a carrying strap attaches to it). The stool is made of polypropylene (plastic), weighs less than three pounds and is designed to support up to 300 pounds. Purchase for $45 at www.steelvisiontools.com.
