Eighteen gauge steel holds up a fully upholstered seat and back on this foldable chair. Upholstered in durable vinyl, this chair will stand up under abuse. The double riveted braces are stronger than the welded versions on most chairs. A padded seat and back give this chair a comfortable edge over most other folding chairs. Strength is an added bonus of these wonderful chairs, with their triple braces and double hinge on each side.
