Solid Wood, Veneer, Plywood, MDF and Particleboard Compared
Two pieces of furniture can look almost identical in a photo and be built from very different materials. The material decides how strong a piece is, how it handles moisture, whether it can be repaired and how long it will last. Here's what each one is and how they compare.
The materials, compared
| Material | Strength and screw holding | Moisture | Repair and refinishing | Weight and cost | Best for |
|---|---|---|---|---|---|
| Solid wood | Excellent; strongest joints | Moves with humidity; tolerates wiped spills | Can be sanded and refinished many times | Medium to heavy; highest cost | Heirloom furniture, tables, chairs, frames |
| Hardwood plywood | Very good on faces; edges need solid wood or banding | Very stable; handles humidity better than MDF or particleboard | Face veneer takes only light sanding | Medium; moderate to high cost | Case sides, backs, drawer bottoms, modern designs |
| Wood veneer over MDF or particleboard | Depends on the core | Stable, but the core swells if water gets in | Light sanding; small veneer repairs possible | Heavy; moderate cost | Figured and bookmatched surfaces, doors, panels |
| MDF | Fair on faces, poor at the edges | Stable when dry; swells when wet | Paint touch-ups only | Heavy; low cost | Painted doors and panels |
| Particleboard | Poor; screws strip easily | Swells permanently when wet | Hard to repair | Heavy; lowest cost | Budget and flat-pack furniture, kept dry |
| Laminate or melamine surface | Tough surface; strength comes from the core | Surface resists water; seams and edges don't | Chips and burns can't be refinished | Low cost | Hard-wearing budget surfaces |
What each material is
- Solid wood: boards sawn straight from the log and joined together. It's strong and holds joints and screws well, and it can be sanded and refinished many times. It also expands and contracts with humidity, so good makers design around that.
- Plywood: thin layers of wood veneer glued with the grain of each layer at right angles to the next. That cross-grain build makes it strong and very stable. Furniture-grade hardwood plywood has a good-looking face veneer; its edges need solid wood or edge banding.
- Wood veneer over a panel: a thin slice of real wood glued to plywood, MDF or particleboard. Veneer isn't a shortcut in itself: it allows bookmatched and highly figured surfaces, and many fine mid-century pieces are veneered. Quality depends on the core underneath and how well the edges are protected.
- MDF (medium-density fibreboard): wood fibres pressed with resin into a dense, perfectly smooth sheet. It's the best base for painted finishes and very flat. But it's heavy, holds screws poorly in its edges, swells if it gets wet and sags under steady weight.
- Particleboard: wood chips and sawdust bonded with resin. It's the cheapest option. It's weaker than MDF, screws strip out easily, and water damage is permanent. It's almost always covered in laminate or melamine.
- Laminate and melamine: a printed paper or plastic surface bonded to a panel, usually particleboard. It's tough against everyday scratches and stains, but a chip or burn can't be sanded out or refinished.
How to tell what you're looking at
- Follow the grain around the edge. On solid wood, the pattern on the top continues down the edge and shows end grain at the ends. On veneer, the edge is a separate strip or the grain stops abruptly.
- Look underneath and inside. Undersides, backs and drawer boxes show the core material. Look for exposed chipboard, fibreboard or layered plywood edges.
- Check for repeats. A printed laminate repeats the same knot or streak across panels. Real wood never repeats exactly.
- Feel the weight. MDF and particleboard pieces are often heavier than you'd expect. Solid softwood pieces are often lighter.
- Read the label carefully. "Solid wood" may describe only the legs or frame. "Wood veneer," "engineered wood" and "wood-grain finish" mean different things. Ask which parts are solid wood.
Which material is right?
For heirloom pieces you'll keep, sand, refinish and pass on, choose solid wood or high-quality plywood with solid wood edges. For painted pieces and wide, dead-flat panels such as cabinet doors, MDF is a good choice. For short-term, budget or rental furniture, particleboard with laminate or melamine is fine, as long as it stays dry and doesn't carry heavy loads. Shelves are where materials differ most: a 3/4" (19 mm) MDF shelf loaded with books starts to sag visibly past about 17" (43 cm), while the same shelf in solid white oak can span about 36" (91 cm).
