We love the mix of sleek white Corian and richly hued woods in The Duo line of furniture from Gravitate, a UK company specializing in furniture made with Corian. The Duo Bookcase is especially appealing, with its 15.7-inch-thick finger-jointed walnut shelves and solid Glacier White Corian side panels; £839 (the same bookshelf with beech shelves is £455).
