- MDF: MDF (Medium-density fibreboard) is a wood derivative. Resins (glues) are used in its production to bond the wood fibers, which are compressed with special heated presses. It is denser than chipboard and resistant to wear. Additionally, it does not absorb any moisture.
- Metal: It is extremely resistant to wear, ideal for furniture intended for daily use in a demanding environment. Besides the properties mentioned above, metal can also have other characteristics, such as antimicrobial action (copper) or superconductivity (molybdenum).
