A movable base support for a medical examination chair permits movement of the examination chair to provide a space allowing a wheelchair to be positioned adjacent medical instruments. The base support for the examination includes a power unit pivotally mounted to a rear of the platform and biased towards the floor. The bias force ensures that the power unit maintains contact with uneven floor surfaces. A guide system assembly limits the range of movement, and allows the examination chair to be returned to a precise original location adjacent to medical instruments.
