Wood or Laminate?

The fastest way to identify what you're dealing with is to look at an exposed edge. Open a drawer. Look at the back of the piece. Check the underside of a shelf.

• Solid wood: The edge grain matches the face grain. Continuous wood fibers throughout.
• Plywood: Thin layers stacked like a sandwich. Usually 5-7 visible layers. This is actually quality construction.
• Particle board: Compressed sawdust and wood chips. Rough, crumbly texture. No visible grain.
• MDF: Smooth, dense, uniform brown throughout. Fine, almost powdery texture at edges.

Cross-section comparison of wood types

Solid wood furniture is noticeably heavier than its laminate equivalent. Pick up a drawer or try to lift one end.

• Surprisingly heavy? Likely solid wood or high-quality plywood. Old-growth hardwoods are dense.
• Light for its size? Likely particle board or MDF with laminate surface.
• Medium with hollow knock? Could be frame with thin panels — check other tests.

A solid wood dining chair: 15-20 lbs. A laminate equivalent: 7-10 lbs. You'll feel it.

Weight comparison between solid wood and laminate

Knock on the flat surface with your knuckles. The sound tells you what's inside.

• Solid, dense thud: Solid wood. Similar to knocking on a cutting board.
• Slightly resonant thud: Plywood or quality construction.
• Hollow echo: Thin panel over air gap. Common in cheap furniture.
• Flat, dead sound: MDF or particle board with laminate.

Knock test sound comparison

Only do this on a hidden spot — underside of shelf, back of leg, inside drawer. Use your fingernail or a coin.

• Solid wood: Scratching reveals more wood underneath. Color and grain continue.
• Veneer: Very thin layer of real wood over a substrate. Scratch through and you hit different material.
• Laminate: Reveals white or brown paper/resin layer. The "grain" is literally a photograph.
• Thermofoil: Surface may peel or lift. It's a plastic film heat-wrapped around MDF.

Important: Veneer over plywood is NOT cheap furniture. Many antiques use veneer.

Scratch test results on different materials

This test you can do from across the room.

Real wood grain is unique. No two boards have the same pattern, ever. Laminate uses a printed photograph — manufacturers repeat the same images.

• How to check:
• Stand back and look at the overall surface
• Look for repeating patterns — same knot, same swirl, same streak
• Check if multiple drawers have identical grain patterns
• On table tops, look for a seam where the pattern starts over

Real wood vs laminate grain comparison

• Solid hardwood — Almost always worth saving. Route to resale, consignment, repair. Value: $50-500+
• Solid softwood (pine, cedar) — Worth saving if sound. Route to resale, donation, repurpose. Value: $20-150
• Veneer over plywood — Often worth saving, especially mid-century. Can be repaired. Value: $30-300+
• Veneer/laminate over particle board — Functional value only. Donate if good, dispose if damaged. Value: $0-30
• Laminate/thermofoil over MDF — Similar to particle board. Donate if functional. Value: $0-20

Sacramento note: Habitat ReStore on Stockton Blvd accepts solid wood furniture but will not take particle board. Knowing the difference saves wasted trips.

Material routing flowchart

Find a piece of furniture in your home — bookshelf, dresser, desk, nightstand, chair.

1. Run through all five tests:
2. Edge test — What do you see?
3. Weight test — Heavy or light?
4. Knock test — Dense thud or hollow echo?
5. Scratch test — What's under the surface?
6. Grain test — Does the pattern repeat?
