This super-thin chair can fold to tuck away in a closet, but you might want to hang it on the wall after the dinner party. The frame is constructed of welded and hinged 3/4” steel angle with exposed hardware. Seat and back are constructed of a lightweight substrate laminated with closed cell foam enclosed in a fabric slip cover, for a perfect balance of support and comfort. These chairs have passed the 3-hour dinner party test many times with flying colors.
