UK-based Gray Concrete created this concrete Chesterfield sofa for exhibiting at 100% Design London. The sofa is made by taking a mold from a real Chesterfield, which is then used to make a glass textile reinforced casting. The cushions are a part of the casting. Before making the mold, the padding inside the cushions was replaced with a rigid foam which was modeled to make “bum prints.”  The molding techniques used by Gray Concrete pick up detail really well so the concrete sofa really looks leathery. There’s even a concrete 50p piece stuck down behind one of the cushions to complete the realistic effect.
