SEAT HEIGHT MEASUREMENT DETAIL

Regardless of measurement technique used, the height is measured at the highest point of the seat, inclusive of bolsters, with the foam in an uncompressed state. Measuring to the top of the bolster would account for the maximum transfer height differential from a wheeled mobility device.

Note that examination tables and chairs only use bolsters on certain areas of the transfer surface. Lower parts of the transfer surface (such as the front edge) would have an even lower height. For reference, ¾ inches is a typical bolster height used on many examination tables. Due to their narrower seating surfaces and the increased need to support the patient securely, examination chairs often have deeper bolsters. Dental chairs, for example, have a typical 1 ¼-inch bolster height.
