Abstract
A multiple mode massage chair is provided for being interchangeably used as a seating support and a massaging platform. Above the conventional components of an advanced chair construction such as a horizontal base with a number of casters for slidably supporting the base over the floor, an upholstered seat bottom and seatback assembled to the base through a telescopic upright stand for a height adjustment from the base, the invention provides pairs of elongated cushion flaps pivotally attached to the seat bottom and seatback for selectively providing an extra cushion to the seated user on the respective seating surfaces. Each flap is shaped to flap on a bi-level pivot action to cover or expose an underlying massage surface of the chair with the assistance of a toggle action in order to facilitate the change of the mode of operation of the chair.
