Abstract

A stool includes a post with a seat and a base respectively connected to a top end and a lower end of the post. A foot rest having a tube located at a center of the ring is movably mounted to the post. A C-shaped secure bush is received in the tube and mounted on the post. The tube has a semi-circular lip extending from an end thereof and a secure piece has a fist end pivotally connected to a first end of the lip. A second end of the secure piece is connected to a second end of the lip by a quick release device so that the secure piece pushes the secure bush toward the post by operating the cam device. The position of the foot rest can be adjustable by operating the quick release device.
