Abstract
A stool can include a base including at least three legs with each leg including a non-slip member and a spring-loaded caster. A lower helical spring may be coupled to the base. A connecting member may comprise a first end coupled to the lower helical spring, a second end opposite the first end, and a central axis that extends between the first end and the second end. An upper helical spring may be coupled to the second end of the connecting member. A rotational joint may be coupled to the upper helical spring. A seat may be coupled to the rotational joint and configured to rotate about the central axis of the connecting member. The base, lower helical spring, upper helical spring, rotational joint, and seat may share a common vertical axis with the central axis of the connecting member when at rest.
