Generally means that all the exposed pieces of wood are solid; hidden areas of the furniture (such as the back), may be made of another material

Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material. Engineered wood includes plywood, oriented strand board (OSB) and fiberboard.
