This term indicates that the exposed parts of the furniture so marked, is made of hardwood or softwood lumber.

Can mean one single board or plank of wood or also several wood boards or blocks that are glued together.

Wood thicker than three millimeters (approximately an eighth of an inch).

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.
