A portable seating apparatus includes a frame having first and second sides. A seat is disposed between the first and second sides of the frame. The seat is suspended between the first and second sides of the frame by multiple tension members such as straps. A first arm rest and first base member are positioned on the first side of the frame, and a second arm rest and second base member are positioned on the second side of the frame. One or more straps extends downwardly from each arm rest to support the suspended seat. In some embodiments, the first and second sides are hinged such that the seating apparatus may be folded for transport and storage. An arm rest hinge is disposed on each arm rest, and a base member hinge is disposed on each base member in some embodiments.

A portable lumbar support and ergonomic chair having a lumbar support. The lumbar support has a seat hingedly coupled to a seat back having a teardrop-shaped lumbar support seat back cushion. A rigid back support portion may be rotated forward about hinges to collapse substantially parallel to the seat frame and backward to open to a variety of angles with respect to the seat frame. The seat back freely pivots around an upper lateral axis, and the rigid back support portion is linearly adjustable to space the seat back toward and away from the hinges to enable raising or lowering the upper lateral axis and thus the seat back with respect to the lower lateral axis. This provides multiple ways of changing which part of the teardrop-shaped lumbar support curve hits your lumbar curve for proper support. Variable lumbar lordotic support is thus provided.

A foldable cloth-embedded bleacher seat has two symmetrical armrest assemblies, a backrest assembly, a cushion assembly and a hook assembly. The backrest assembly has a detachable backrest cloth. The cushion assembly has a detachable cushion cloth cover. A lower part of each of the two sides of the backrest assembly is rotatably connected to the upper side of one armrest assembly, and the bottoms of the two sides of the backrest assembly are rotatably connected to the two sides of the cushion assembly. The lower sides of the two armrest assemblies are rotatably connected to the two sides of the cushion assembly. The hook assembly is detachably installed on the lower surface of the cushion assembly. The bleacher seat is foldable, thereby occupying a small space and being simple, attractive, elegant, firm and durable in overall structure, and convenient and fast to fold and unfold.

A portable collapsible chair may include a frame that may be collapsed to enable a user to carry or store the chair and that may be expanded to form a chair on which the user may sit. The chair may further include a backrest coupled to the frame, a seat coupled to the frame, and one or more heat exchangers. The chair may also include a control circuit coupled to the one or more heat exchangers. The control circuit may provide a first signal to at least some of the one or more heat exchangers to warm the chair in a warming mode or may provide a second signal to at least some of the one or more heat exchangers to cool the chair in a cooling mode.

A lumbar traction device for treating a lower back of a user includes a shell that is coupled to and extends from a rear edge of a panel. The shell and the panel are configured to position on a seat and in abutment a backrest of a chair, respectively. A coupling means that extends through a front of the shell is coupled to a plate positioned in the shell. The coupling means is configured to couple to a torso of the user to couple the user to the plate. An actuator, which is positioned in the shell and operationally coupled to the plate, is positioned to selectively raise the plate relative to the seat of the chair. The coupling means is configured to transmit an upward force from the actuator to the torso of the user to place a lumbar region of a spine of the user in traction.

A bleacher seat having a cloth cover, tube insertion sleeves and a bleacher seat support assembly. The bleacher seat support assembly has two foot pad tube assemblies, two back tubes, four tube plugs, four seat tubes, a middle cross tube, two connectors, and two elastic ropes. Each connector is of a four-way connecting port structure. Horizontal connecting ports of the two connectors are respectively connected to two ends of the middle cross tube, front connecting ports of the two connectors are respectively connected to the foot pad tube assemblies, two upper connecting ports which are internally communicated with each other are formed in the upper end of each connector, each upper connecting port is connected to the lower end of one seat tube, and the upper end of each rear seat tube is connected to one back tube.
