<p>A massage chair (10) includes a seat (50), a front upper support assembly (16), a first support surface (18) and a first positioning mechanism (20). The first positioning mechanism (20) movably secures the first support surface (18) to the front upper support assembly (16). The first positioning mechanism (20) includes a guide rail (24) that has a longitudinal axis (26), and a clamping assembly (27) having a rotational axis (28). In some embodiments, with a single adjustment, the clamping assembly (27) can move between a locked position that inhibits movement of the first support surface (18), and an unlocked position that allows movement of the first support surface (18) around the rotational axis (28) and along the longitudinal axis (26). The massage chair (10) can also include a second positioning mechanism (22) that movably secures a second support surface (75) to the front upper support assembly (16).</p> |
