How to tell solid wood from chipboard, MDF and veneer

In short: Solid wood is timber cut from the trunk, and its grain runs from the face over the edge. Chipboard is pressed wood chips covered in a printed film, MDF is pressed fine fibres, and veneer is a thin sheet of real wood glued over chipboard or MDF. In a shop, look at the edges, check whether the grain pattern repeats, look at the assembly fittings, then ask in writing what each part of the bed is made of.

Plenty of beds are described as "wood". Technically that's not a lie: chipboard and MDF are made from wood. The difference shows a few years later, when you move house or the first deep scratch appears. Here's how to tell them apart before you pay.

The four materials

Solid wood is natural timber, cut from the trunk and dried. Wide surfaces are usually made from several strips glued edge to edge; that's still solid wood, because every strip is full-thickness timber.

Chipboard (particleboard, often sold as melamine-faced chipboard) is made from wood chips mixed with resin and pressed into a board. The face is covered with a melamine film, usually printed to look like wood, and the edges are covered with a glued-on strip called edge banding.

MDF is a board made from very fine wood fibres pressed with a binder. It's uniform and smooth and easy to machine and paint, so it's common on painted fronts and shaped pieces.

Veneer is a thin sheet of natural wood glued onto a backing board, usually chipboard or MDF. It looks like wood because it is wood, but only on the surface; underneath is the board.

How to tell them apart in a shop

The edges tell you most

On solid wood, the grain on the face carries on over the edge, and at the ends you can see the tree's growth rings. On chipboard, the edge is covered with banding: a strip with a visible seam at the corners, sometimes a slightly different shade from the face. On a veneered piece, the pattern on the face doesn't continue onto the edge, and the edge has a separate strip.

Does the pattern repeat?

A printed film repeats the same image. If you can see the same knot or mark on two different pieces, it's a print. Solid wood never repeats exactly: each board has its own grain, knots and colour variation. Veneer is unique too, but sheets cut from the same block are often laid in mirror pairs, like the pages of an open book, and that symmetry is a clue.

Look where nobody looks

Check the underside of the side rails, the back of the headboard and the screw holes. A hole drilled in chipboard shows compressed chips; in MDF, an even brown mass like dense cardboard. In solid wood, you see wood all the way through, with the same grain.

The assembly fittings

Cam locks (the round fittings you tighten with a screwdriver), dowels and metal brackets are typical of flat-pack furniture made from boards. Solid wood can be screwed together too, so fittings alone prove nothing. But if a bed's main joints are nothing more than cam locks in boards, it's very likely chipboard or MDF.

Weight isn't a reliable test

MDF is dense and heavy, and some solid woods are light. Weight can mislead you either way, so only use it alongside the other signs.

Wording traps in product descriptions

Most of the confusion comes from phrases that sound like wood without promising solid wood:

• "wood finish", "wood effect", "oak decor" – usually a printed film over chipboard or MDF;
• "wooden", with nothing more specific – can include chipboard and MDF, which are wood-based;
• "solid wood frame" – may mean the rails or legs are solid, while the headboard and sides are board;
• "veneered", "real oak veneer" – real wood on the surface, board underneath;
• "solid wood" at a price far below other solid wood beds – worth an extra question.

The simplest protection: ask in writing what each component is made of (headboard, side rails, legs, mattress support) and how the joints are made. A seller who knows will answer in a few lines. When buying online, also ask for a photo of an edge and of the underside of a side rail.

Compared: durability, repairs, price

Chipboard isn't a "bad" material. It's cheap and fine for furniture you know you'll replace in a few years. The problem is paying solid wood money for it, or using it where it carries weight every day.

Why it matters for a bed in particular

A bed carries weight every night, flexes slightly every time you turn over, and gets taken apart every time you move. Joints in board are what fail first: threads wear, cam locks work loose, and the creaking starts. If yours already creaks, see the guide to caring for a solid wood bed.

Solid wood with traditional joinery behaves differently. A Massif frame held a static load of 1,400 kg with no measurable deformation; the details are in the guide on how strong a solid wood bed is. Many cheap frames give way far sooner.

Where we use MDF ourselves

To be completely straight: at Massif, every structural part is solid wood, with no chipboard and no veneer on the structure. We use MDF in two places: drawer bottoms and the backs of chests of drawers. Those parts only need a flat panel that doesn't carry the bed's weight and plays no structural role.

The joints are mortise and tenon, with no metal brackets and no glue in the structural joints, so the bed can be assembled and taken apart as often as you like. The structure carries a 30-year warranty.

And the downsides, stated plainly: a solid wood bed costs more than a chipboard one, and because each one is made to order, the standard lead time is 40–50 working days before dispatch.
