	* [https://en.wikipedia.org/wiki/Medium-density_fibreboard '''Medium Density Fibreboard (MDF)'''] is a composite panel product made by combining wood fibres with a synthetic resin and bringing them together under heat and pressure. It has a relatively hard, flat, smooth surface free of knots, rings or other blemishes. It is not as strong as plywood, tending to sag more easily under weight, and so benefits from the addition of solid wood edgings or similar if used for shelving for example ''(as ~~does~~ '''~~Chipboard~~''')''.		* [https://en.wikipedia.org/wiki/Medium-density_fibreboard '''Medium Density Fibreboard (MDF)'''] is a composite panel product made by combining wood fibres with a synthetic resin and bringing them together under heat and pressure.

	'''Chipboard''' has had a major influence of the design of interior and flat-pack furniture - and especially kichen units since the 1950's.
