Furniture prices span an enormous range, and the relationship between price and durability is real but inconsistent. The good news is that most of what determines whether a piece lasts is visible or testable in a few minutes, if you know where to look.

Materials, from most to least durable

Solid wood can be repaired, refinished and re-joined, and it lasts generations. It is heavy, it moves with humidity, and it is expensive.

Plywood is layers of wood glued with alternating grain. Good quality plywood is strong, stable and holds screws well — genuinely excellent material, not a compromise.

MDF is compressed wood fibre. Stable, smooth, takes paint beautifully, and reasonable for panels and shelving in moderate spans. It sags under sustained load and is badly damaged by water.

Particleboard or chipboard is wood chips bonded with resin, usually with a printed foil or laminate surface. Cheap and light. Screws pull out easily, it sags readily, and it disintegrates if it gets wet. Furniture built from it generally survives one or two flat-pack assemblies and not a house move.

To identify what you are looking at, check an unfinished edge or the underside, and look at the back panel. A very thin hardboard back stapled on is a sign of budget construction throughout.

Joints tell you most of the story

How pieces are connected matters more than what they are made of.

Dovetail joints, the interlocking wedges visible on the sides of drawers, are the traditional marker of quality drawer construction. They resist being pulled apart, which is exactly the force a drawer front experiences.

Mortise and tenon joints, where a tongue fits into a matching slot, are the standard for durable chair and table frames.

Dowels and biscuits are a reasonable middle ground, common in decent flat-pack furniture.

Cam locks and screws into particleboard are the flat-pack standard. Convenient and repeatable, but they loosen with movement, and the holes wear.

Staples and glue alone in a structural position is a warning sign.

Corner blocks — small triangular reinforcements inside corners — indicate a maker thinking about longevity. Their presence in sofa and chair frames is a good sign.

Testing in the showroom

Do these things. Staff expect it.

  • Lift one corner. Weight usually indicates solid material. A very light bookcase is particleboard.
  • Push it diagonally. A well-built piece resists racking. Noticeable wobble means weak joints, and it will worsen.
  • Open and close every drawer. They should run smoothly, and pull most of the way out without tipping. Look for dovetails and a solid drawer bottom sitting in a groove rather than stapled underneath.
  • Sit on chairs and sofas properly. Shift about. Listen for creaking. Check whether you can feel the frame through the padding.
  • Look underneath. This is where corners get cut. You want a proper frame, not stapled cardboard.
  • Check the back. A solid or thick back panel screwed in place beats thin hardboard stapled on.

Upholstery specifics

For sofas and armchairs, the frame is what determines lifespan. Kiln-dried hardwood is the durable standard; softwood and particleboard frames are cheaper and shorter-lived. Ask — reputable retailers will tell you.

Suspension sits between the frame and the cushions. Eight-way hand-tied springs are the traditional premium method. Sinuous serpentine springs are the common middle option and perfectly good. Webbing alone is the cheapest and sags soonest.

Cushion filling. High-density foam holds shape well; feather and down is comfortable but needs regular plumping; a foam core wrapped in feather is a common and effective compromise. Ask about foam density, since low-density foam flattens within a couple of years.

Covers. Removable, washable covers extend usable life considerably. For fabric durability, the rub test count — a measure of abrasion resistance — is often quoted, and higher numbers suit heavy household use.

Where to spend and where to save

Spend on what you use daily and what bears weight: the sofa you sit on every evening, the mattress, the dining chairs, the desk chair. These are used for thousands of hours and failure is genuinely inconvenient.

Save on occasional and decorative pieces, on anything for a room whose use may change, and on furniture for children, which gets outgrown and damaged regardless of quality.

The second-hand argument

Older furniture is frequently better made than new furniture at the same price, because solid wood and traditional joinery were standard. Auctions, charity shops and local listings routinely have solid wood pieces for less than new particleboard equivalents.

Check for woodworm holes, structural cracks, and whether joints are loose — loose joints in solid wood can usually be re-glued, which is a genuine advantage over materials that cannot be repaired at all. Upholstered second-hand items need more care: check for damage and odours, and be aware that fire safety labelling requirements vary by country.
