Abstract: A surgeon's operating stool 10 is provided which is readily movable when not occupied by a person but resists undesirable movement once a person has occupied the stool 10. The stool is provided with a series of rollers 20 which normally support the stool 10 and allow for movement in any desired direction. However, the rollers 20 include a spring loaded collapsible mechanism which, when occupied by a person, forces the rollers 20 to retract into the base 12 of the stool 10 and causes a nonskin surface 38 to engage the floor. The base 12 of the stool 10 is configured to receive the feet of a person using the stool, such that a person using the stool in either a standing or sitting position forces the retracting mechanism to remain retracted and thereby prevent undesirable movement during use. The stool 10 also includes a hydraulic height adjusting mechanism which is readily adjustable via foot operation.
