Stacking & Folding Chairs — Expert Answer
What happens if stacking chairs are left outdoors in wet weather?
Steel-frame stacking chairs will begin to rust if left outdoors in wet conditions, even with powder-coat finishes — water penetrates seams, screw holes, and scratches. Padded upholstery will absorb water, promote mold growth, and deteriorate rapidly if left exposed to rain. For permanent outdoor storage, only chairs specifically designed for outdoor use (aluminum frames, solution-dyed fabric or polypropylene shells) should be used. Steel indoor stacking chairs can be temporarily used outdoors for covered events but must be stored indoors or in a dry covered area immediately after use.
