Why is plywood useful for drawer bottoms and the backs of storage furniture?

Plywood is an ideal material for drawer bottoms and the backs of storage furniture primarily due to its dimensional stability and resistance to splitting.12

Unlike natural wood, which can expand, contract, or warp significantly in response to changes in temperature and humidity, plywood maintains its shape and size under varying environmental conditions. This stability is achieved by gluing together thin sheets of wood with the grain of each layer oriented perpendicularly to the next, which provides uniform strength and prevents the material from warping or splintering.12

Because these components—such as drawer bottoms and cabinet backs—are often thin and must remain flat to function correctly within a furniture frame, plywood’s ability to resist atmospheric changes makes it a highly reliable and cost-effective choice for cabinetry and storage construction.12
