Walkstool Basic comes in two different sitting heights: 20"" and 24"". The seat is made of black polyester and is approximately 20% bigger in size than a normal seat for a three legged stool. The legs are grey to match the seat. Walkstool Basic has a similar light weight construction as the Walkstool Comfort models, including telescopic legs in aluminum. It is manufactured in China with a quality high enough for most people to use it for many years. Walkstool is the only three legged telescopic stool in the world with patents and trademark protections.
