Abstract: An adjustable work table is disclosed comprising a frame having spaced apart sides (6), a horizontal shaft (60) supported between the sides of the frame, and a table surface assembly (10) rotatively mounted to the shaft. Camming angular adjustment means (98, 110) is provided for rotating the table surface assembly into selective angular positions about the shaft. Vertically actuating scissor arms (44, 46) are further provided for moving the support shaft upward and downward whereby providing a vertical adjustment.

Abstract: An adjustable foot support (10) includes a platform (38) upon which the feet may be placed and a base (14) to support the platform (38). A bracket assembly (26) extends upwardly from the base (14) and has a plurality of stepped channels (28) which selectively cooperate with a downwardly extending leg (41) from the platform (38) so that the platform (38) is selectively inclined with respect to the base (14).
