The shelves are made of excellent quality melamine, with 18mm thickness. Melamine is a type of wood in chipboard form. Chipboards are products that have the form of a panel and come from the welding, through pressing, of small pieces of wood (usually fir, beech, spruce, etc.) with the help of various resinous liquids. The chipboard is then coated, usually with synthetic materials such as hard paper sheets (melamines). As a material it is very durable and with great hardness. So, it is a synthetic material with a very hard surface, making it very resistant to scratches, abrasion, and stains.
