    摘要: A seating unit with a flexible seat back having an upper portion separated into two halves positioned to support a user's back at opposite sides of his spine, and with these halves being mounted for resiliently resisted rearward deflection relative to one another in order to accommodate movement of the user's body, and with a slit or the like being provided at the center of the back between these halves to enable projection of the user's spine rearwardly beyond adjacent portions of the user's back for optimum comfort at all times. The back structure may be connected to a generally horizontal seat element, which may be bifurcated to have two relatively movable forwardly projecting portions. The device may also have an anchoring portion for detachable connection to a cushion of an upholstered seat on which the unit is to be used.
