Abstract: A shoulder support system for a chiropractic or medical treatment or massage table. This table may have a main upper surface with a well or wells extending down throughout or it may have a plurality of table members. It includes two shoulder support members with a recess between them. A patient lying properly face down on the table is supported by the shoulders in contact with the shoulder support members. Where the patient is a woman, her breasts rest in the recess between the shoulder support members, being supported out of contact with the table, so that the table does not exert substantial force on her breasts. The shoulder supports are mounted on a base which may be supported by the table substructure at adjustable heights. The shoulder support members may be adjustable laterally, so that the distance between them can be varied to accommodate patients with different shoulder widths and breast sizes, all relative to the plane on which the patient is lying.
