Portable stool by Duluth Trading Co.

The Walkstool is a compact three-legged stool with a comfortable, industrial grade mesh seating area that has been tested to hold up to 880 pounds. The unit weights 22 ounces and folds down to the size of a thermos bottle so it can be carried on a tool belt or bag. The telescoping legs may be adjusted to two heights: one for work in lower positions and the other fully extended. It is available in 18- and 22-inch models.
