ABSTRACT:
A dental operating chair includes a movable back member which can be adjusted to position a patient in a substantially supine posture. Arcuately formed arm supports which curve toward the patient are removably secured along the opposite longitudinal sides of the back member to retain the arms of a patient proximate his body truck. The arm supports include means which permit them to pivot toward and away from the patient. The internal surfaces of the supports are shaped to clasp the patient's arms and the edges of the supports are shaped for easy contact by the body of a dentist to cause them to pivot toward the patient.
