A seating structure includes a shell having a central portion, opposite outer peripheral edges laterally spaced from opposite sides of the central portion, and at least one biasing array disposed between each of the opposite sides of the central portion and a respective outer peripheral edge. Each of the biasing arrays includes a plurality of spaced apart support members and at least one connector connecting adjacent support members within each array. The biasing array may include a plurality of biasing arrays, with at least one connector connecting adjacent biasing arrays. A second shell may be connected to the outer peripheral edges of the first shell, with an open space defined there between. Each of the opposite outer peripheral edges is independently deflectable in response to a load being applied to the second shell.

The present disclosure relates to a functional chair for human body correction and therapeutic efficacy promotion by applying heat, including: a main body which includes a sitting plate and a waist plate; a heating means to transfer the heat to a human body by using a ceramic heating element installed in the sitting plate and the waist plate; and a control unit which maintains the temperature of the heating means at a pre-established value and displays an operating status. The present disclosure provides immunity increase and health promotion by keeping a skeletal structure and organs balanced by allowing a user to keep a correct posture when they are sitting on the functional chair and by applying heat to a structure including the sitting and waist plates as a Korean traditional floor heating system, which has no influence of electromagnetic waves, does, provides convenience of portability and performs therapeutic effects for various body parts including the vertebral column, calves, feet, etc.

A foldable bench having a seat and front support members that may be rotated between a folded position and an unfolded position includes a backrest, first and second front support members, a seat, and a latch. The front support members are mounted to the font of the backrest and rotate laterally between a folded and unfolded position. The seat is mounted to the front of the backrest and rotates vertically between a folded and unfolded position. In the folded position, the seat is sandwiched between the backrest and the front support members. In the unfolded position, the seat prevents the front support members from rotating inwards to the folded position. The seat is supported in an unfolded position by seat supports located on each of the front support members, which are received by receivers in the seat. A latch located on one of the arms selectively engages an opening in the seat to secure the seat in the unfolded position.

A seating arrangement includes a seat arrangement that includes first, second, third and fourth link members coupled to one another, a back arrangement movable between an upright position and a reclined position and coupled to the seat arrangement such that the first link member moves between forward and rearward positions as the back arrangement is moved between the upright and reclined positions, and a stop arrangement including a stop link coupled to at least one of the first link member, the third link and the fourth link member such that the stop link moves with the associated link member as the back assembly moves between the upright and reclined positions, wherein travel of the stop link is limited with respect to the second link member thereby limiting a rearward movement of the back arrangement toward the reclined position.

A seat board of a foldable chair includes a panel and a bottom frame. A top portion of the bottom frame is bent to form an annular inner blocking edge and an annular outer pressing edge, and an annular installation groove is formed between the annular inner blocking edge and the annular outer pressing edge. The panel form an annular folded-downward edge, and the annular folded-downward edge is inserted into the annular installation groove. The annular inner blocking edge cooperates with the annular outer pressing edge to clamp and secure the annular folded-downward edge. Two elongated sliding slots are symmetrically located on outer side edges of a right side and a left side of the bottom frame, and the two T-shaped rivets are slidably connected to the seat board and chair legs.
