How to judge the quality of wood furniture
Look for solid wood.
If a store claims that a piece of furniture is solid wood, that means that it only contains wood. Plywood, on the other hand, is layers of wood and resin or glue.
Solid wood tends to be more durable, though it is usually more expensive. If you can see an unfinished edge of the furniture, you should be able to tell if it's plywood or solid wood.
