A bench top for a bench seat includes mounting elements for coupling to sides of bench seat members and a seat unit. The seat unit includes: a seating top; front and back members extending generally away from the seating top; ribs extending inwardly from the front and back members that, together with a front lip and a back lip, provide front and back pockets for receiving respective mounting elements therein; and joining elements at opposing sides of the seat unit for cooperating with joining elements of adjacent units. The seat unit is resilient to move the front and back lips away from each other for installation over the mounting elements and to return to a less flexed state as the front and back lips move toward each other when the mounting elements are received in the front and back pockets.

A chair, according to the present invention has an inverted pyramidal shape primarily determined by triangular side and back frames of the chair. The frames include two side frames and a back frame and preferably a smaller front frame. Each side frame is secured to a central portion of a pedestal type base and extends upwardly and outwardly from the base. Each frame adjacent an upper edge is mechanically secured to an adjacent frame with the frames cooperating to form a U shape generally at the height corresponding to side arms of the chair. A support seat is provided in the frames and the side frames define arms of the chair. A back support is secured to the back frame at a position intermediate the height of the back support with a lower edge of said back support joining with a rear edge of the support seat. The side frames and back frame between said seat and an upper edge of the frames are of a triangular or truncated triangular shape.

A back lifting chair designed for treating and preventing back problems by reducing pressure on a user's spinal disc. The chair provides an up-lifting motion on the user's torso, reducing the weight and pressure asserted on the lumbar disc, and preventing any further damage to it. The chair can be modified from an existing chair. In one configuration, a torso lifting harness which can lift the user's upper torso is connected to the backrest of the chair. The back rest of the chair provides an upward and downward movement, hence partially or completely lifting the user from the seat, effectively reducing the pressure on the user's spine and back. The upward motion can be initialized by the user, or alternatively, it can be automatically activated by the weight sensor installed on the seat area which detects the prolonged period of sitting.

The seat unit includes: a seating top; front and back members extending generally away from the seating top; ribs extending inwardly from the front and back members that, together with a front lip and a back lip, provide front and back pockets for receiving respective mounting elements therein; and joining elements at opposing sides of the seat unit for cooperating with joining elements of adjacent units. The seat unit is resilient to move the front and back lips away from each other for installation over the mounting elements and to return to a less flexed state as the front and back lips move toward each other when the mounting elements are received in the front and back pockets.

A folding chair may include a frame that is configured to transition the folding chair between use and storage positions. A seat base may be pivotally coupled thereto at a first particular length from a front end and a receiving portion may be disposed in an upper surface. The receiving portion may include left and right lateral edges, front and rear longitudinal edges, and a depth. The padding material may be disposed in the receiving portion and may have a lateral dimension related to a distance between the front and the rear longitudinal edges, a longitudinal dimension related to a distance between the front and the rear longitudinal edges, and a thickness related to the depth. The padding layer may cover a majority of a top surface of the padding material and of the upper surface. The cover may retain the padding material and the padding layer relative to the seat base.
