David: • Look for solid hardwood construction (avoid fiberboard or MDF).

• Ensure that wood grain and color match closely.

• Choose furniture with wood-to-wood joints that are glued and gap-free.

• Avoid pieces joined with metal fasteners, which tend to corrode and loosen. (If fasteners are used, make sure they’re well hidden.)

• Check that drawers slide in and out easily, even when pulled with one hand.

• Make sure that the wide pieces of wood in drawer bottoms and tabletops are attached in a way—say with sliding dovetails—that allows them to shrink and swell with the seasons. Otherwise, they will crack. Opt for a tough, easy-to-repair finish, such as shellac or a penetrating oil.
