Most people think of cabinets as being made out of wood and that’s true for the most part. But don’t think that it’s all “solid wood” like the lumber used to frame a house. There are other materials that go into the construction of cabinets. Some are wood-based but others are not.
Solid homogeneous wood, all the way through. It will not a fabricated or wood composite, like particle board, Medium-density fibreboard (MDF) or even plywood.
