This category includes essential underlay and support materials used throughout upholstery construction. Dust cloth (also known as celestra cloth, black bottom, or typar) is used on the underside of furniture to conceal webbing and springs. Burlap and synthetic burlap are used to cover coil and zig-zag springs, providing structure, noise reduction, and friction control. Denim/Decking offers durable spring coverage, while muslin is used between foam or cushion wrap and the cover to help shape, protect, and create a smooth finished surface.
