A folding chair of the type having a frame constructed of pivotally connected scissors like "X"-shaped structure strut members supporting a sling seat, the lower ends of which form two front feet and two rear feet and the upper ends of which form two front seat corners and two rear seat corners of the chair. The folding chair includes a pair of upright telescopic supports mounted between the two front seat corners and the two front feet. The upright telescopic supports extend when the frame is folded and collapse telescopically when the chair is deployed. A pair of uprights may extend up from the rear feet and through the rear seat corners so as to extend above the rear of the sling seat to provide a backrest.

[ What is claimed is:] [1.]1. A folding chair comprising:"X"-shaped collapsible front and rear structures,"X"-shaped collapsible left and right side structures,said front, rear, left side and right side structures pivotally mounted to each other at adjoining corners of said "X"-shaped structures so that said front and rear structures are parallel and spaced apart and so that said left and right side structures are parallel and spaced apart, said front, rear, left and right side structures when so mounted defining a rectangular parallelepiped symmetric about an axis of symmetry,said rectangular parallelepiped expandable or collapsible symmetrically about said axis of symmetry by simultaneous corresponding expansion or collapsing of said "X"-shaped structures about pivots in the center of each said "X"-shaped structure and said pivotable mounting at said adjoining corners, said adjoining corners forming the vertices of said rectangular parallelepiped,one pair only of telescopic members mounted to, so as to extend between, vertically aligned front vertices of said vertices of said rectangular parallelepiped,wherein said telescopic members are fully telescopically retracted when said rectangular parallelepiped is fully expanded so as to tension a flexible seat suspended between upper vertices of said vertices of said rectangular parallelepiped.
