In furniture, the term overlay refers to a decorative technique or design element where one surface is placed over another surface, creating a layered effect. This can involve applying an additional layer of material, such as a veneer or decorative inlay, onto the surface of the furniture. It is commonly used to enhance the appearance and aesthetic value of the piece by adding texture, pattern, or color contrast. Overlay can also refer to the method of constructing furniture, where one piece is fixed or attached over another piece to create a layered or overlapping effect. Ornamental veneer applied upon the surface rather than inlaid into a veneer surface.
