Abstract An elongated base is provided including front and rear ends and the rear end includes an elevated seat portion. The forward end of the base includes upright standard projecting upwardly to a level above the seat and a rearwardly and upwardly inclined support arm is mounted from the upper end of the standard. The rear upper end of the support arm includes a rearwardly facing chest pad in general vertical registry with and spaced above the forward marginal edge of the seat. The support arm is mounted from the standard for forward and upward swinging of the rear end of the support arm from a lower limit position thereof and the support arm additionally supports a head (forehead) rest supported therefrom at an elevation above the chest pad and mounted from the support arm for front to rear adjustment relative to the chest pad.
