Abstract: A portable supportive seating system allows for a person to move a chair with them and then assemble it in remote locations and there receive support for their back and general posture support from it. A back support has an attachment that allows a rest or seat to be placed through it and holds the person that sits on it. A guard is attached to the bottom edge of the back support to protect it.

Abstract: A lightweight, inexpensive folding chair may have a seat with an interference fit support bracket may be provided. The seat may have a lightweight seat member constructed of a lightweight material, such as a blow-molded plastic, that is generally supported by two such support brackets. The support brackets may be affixed to the lightweight seat member by sliding the lightweight seat member into interference engagement with the support brackets. Thus, the lightweight seat member is supported against bending when the chair is in use, in a way that does not concentrate stresses in the lightweight seat member to cause deformation and failure. The support brackets may have an enclosing shape so that the lightweight seat member is unable to move laterally or transversely out of engagement with the support brackets. The support brackets may thus have lips extending into the lightweight seat member to provide the enclosing shape.

Abstract: This invention relates to a method for manufacturing a separable chair assembly, in particular a type of chair assembly which can be separated, folded, overlapped for storage with least space, characterized in that the chair assembly consists of one back unit and one seat unit, closed matched. The back unit and the seat unit are in an H form with slight curvature looked from a side view. The back unit is designed wider than the seat unit, so the chair assembly can be folded in one piece when not in use. The back unit is furnished with a front retaining board and a rear retaining at the center part. While in use, the back unit and the seat unit will cross each other so as to set the seat unit leaning on the retaining boards thus to form a chair. It is a practicable application for use.
