Mobile folding restaurant booth style benches are provided, which may be arranged in opposed pairs to form restaurant style booths. An individual bench incorporates a mechanism for shifting the weight of the bench between a mobile base, which may be supported by swivel casters, and a stationary base, which may be supported by non-slip feet, actuated by pivoting a bench seat down from a folded storage position to an unfolded seating position. The weight shifting mechanism may include an engagement member, which is initially spaced apart from an actuator at a folded angle of the seat, and which contacts and begins transmitting force and movement to the actuator at a partially unfolded angle of the seat. Preferably, the bench further includes a biasing component that biases the stationary base upward relative to the mobile base.
