A seat is pivotally mounted to a wall by means of at least one hinge assembly, enabling the seat to be folded. The hinge assembly provides an upward and rearward movement as the seat pivots from a horizontal to a vertical orientation during folding. The hinge assembly has a seat mounting bracket mounted to the lower surface of the seat and a wall mounting bracket mounted to the wall. The seat mounting bracket is connected to the wall mounting bracket via a pair of pivoting arms. Each pivoting arm is pivotally connected at one end to the wall mounting bracket and at an opposite end to the seat mounting bracket. The pivot locations are selected such that as the arms pivot in a clockwise direction, the seat mounting bracket pivots in a counterclockwise direction. The pivoting arms can pivot only in a vertical direction, and serve to guide the seat upward from a lower position to a relatively higher position, the seat at the same time being pivoted from a horizontal position to a vertical position, and vice versa.
