A roller mechanism is provided for a massage table which will allow a roller to accurately follow the curvature of a patient's back, and which will maintain a substantially constant pressure on the patient's back. The roller mechanism includes a roller assembly frame which slides beneath the table. A roller frame, on which the roller is journaled, is pivotally mounted to the roller assembly frame so that the roller may move vertically relative to the fame. A spring is connected at one end to an end of the roller frame and at another end to a bracket which is movable vertically relative to the roller assembly frame. The spring biases the pivotal roller frame upwardly to keep the roller in contact with the bottom of the table's cushion on which the patient lies. By changing the position of the bracket, the spring tension can be changed, to alter the pressure exerted by the roller against the patient's back.
