Abstract
A narrow seating device or chair including a support caddy having lockable ground engaging caster wheels and a seat portion for a patient undergoing a medical test. The seat portion is mounted on the support caddy and tiltable to a plurality of tilt positions. The seat portion has a convexly curved surface which rests on spaced apart rollers on the upper side of the support caddy to enable tilting. A linear actuator having a first end attached to the support caddy and a second end connected to the seat portion provides for tiltable movement of the seat relative to the support.
