Abstract: An L-shaped cushion for use with a stringed instrument having a concave lower surface in a body portion when the instrument is in playing position, is formed by a base pad containing a concavo-convex member overlying resilient foam material interposed between the musical instrument and a user's thigh for supporting the mass thereof. The leg pad of the L-shaped cushion similarly includes mass distributing planar plates and foam material interposed between the user's torso and the body of the instrument when in playing position.
