Apparatus for measuring the contour of the back of an individual in a seated position comprises a chair (1) having a base (2), a seat portion (3) and a back portion (4) having upstanding members (25) supporting gear racks (26). The back portion (4) comprises a back engaging member (36) which comprises a sheet member (37) which is deformable to take up the vertical contour of the individuals back. A plurality of spring steel transverse strips (80) are secured by rivets (82) to the sheet member (37). Mounting means (38, 39 and 40) are provided for mounting the back engaging member (36) to the upstanding members (25 and 26). The mounting means (38, 39 and 40) are movable vertically on the upstanding members (26) to deform the sheet member (37) to take up the vertical contour of the individual. Side members (85) are movable inwardly and outwardly to deform the transverse strips (80) to take up the horizontal contours of the individual. |
