A seating structure includes a frame, a carrier, and a suspension material. The frame includes first and second side frame members and first and second cross frame members forming a closed loop and defining an opening therebetween. The frame also includes a plurality of first attachment features on an outer perimeter of the frame. The carrier includes first and second side carrier members and first and second cross carrier members that form a closed loop. The carrier also includes a plurality of second attachment features on an inner perimeter of the carrier. The plurality of second attachment features engages the plurality of first attachment features to attach the carrier to the frame. The suspension material is attached to the carrier and extends over the opening in the frame to define a continuous seat and backrest.

An apparatus for supporting a human body is disclosed. The apparatus has a body assembly configured to support a back of the human body, a head assembly attached to the body assembly via an attachment portion, the head assembly including one or more members forming a recess configured to receive a head of the human body, and a slit disposed between the body assembly and the head assembly, the slit configured to open from a closed position to an open position to provide rotation of the head assembly relative to the body assembly.

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.
