Recommendations on Standards for the Design of Medical Diagnostic Equipment for Adults with Disabilities, Advisory Committee Final Report

Transfer Surface Size – M302.2.2 Seated Position

The issue of seat depth was discussed and decided during the full committee meetings as follows: depth of 17 inches minimum. The Subcommittee discussed the width and agreed on a 21 inch minimum width based on anthropometric data and industry human factors experience. In addition, examination chairs that cannot be entered on the foot end, such as dental chairs and podiatry chairs, the subcommittee members agreed that the 17 inch minimum depth and 21 inch minimum width be located on both sides of the chair to allow for a left or right transfer (see examples below).
