What a cabinetmaker checks first when buying furniture

· 9 min read

Anyone who has done a cabinetmaking apprenticeship looks at a piece of furniture in a particular order. It is not the form that comes first, but the places where corners can be cut without it showing in the product photo.

This trained eye can be described and therefore also adopted. It does not follow intuition but a fixed sequence of checkpoints: edge, board thickness, joints, upholstery construction, small parts. This text goes through that sequence.

First: the edge

The surface of a piece of furniture is shown; the edge is rarely photographed. That is exactly why it comes first.

The edge reveals the type of construction – solid wood, veneer or coating. With solid wood, the grain of the surface continues over the edge into the material. On the two ends, where the fibres are cut across, it shows as end grain, whereas the long edges show the continuous fibre. With veneer, a thin top layer sits on a substrate, and the edge shows how this transition has been handled. With coated boards, a glued-on edge band takes on this task.

Edge bands are not fundamentally a bad sign, but how they are made reveals a lot. A cleanly applied, thicker band with a softened edge lasts for years. A thin paper band with a visible glue line comes loose at the edge as soon as moisture gets to it – usually first in the kitchen and bathroom. To check, run a fingernail across the edge: if it catches, the joint is open.

Then the care taken over the finish: is the transition from the surface to the edge sharp or softened? A slightly softened edge not only feels better, it also lasts longer, because a sharp edge chips at the first knock.

It is particularly worth looking at the fronts of doors and drawers, because these edges are touched most often. A rounded front is therefore rarely just a design decision. It is also the place where a piece of furniture keeps its first-day look the longest.

Then: the board thickness

A figure in millimetres says more about a piece of furniture than any adjective. For solid table tops, a thickness of about 30 millimetres (1.2 in) or more is considered solid. With inexpensive tables the figure is often 18 or 22 millimetres (0.7 or 0.9 in) – and that is precisely why it is often missing from the data sheet.

Thickness never matters on its own, though, only in relation to the span, that is, the distance between the points on which the board rests. A thin board on a narrow base holds without any problem. The same board over two widely spaced supports sags towards the middle. Anyone planning a long shelf therefore allows either for more thickness or for an additional support in the middle. With shelves made of chipboard or fibreboard, visible sagging after a few years is the rule if the span chosen was too wide.

Thickness is therefore not an end in itself. It decides whether a board stays flat over years or sags towards the middle, and whether, after the tenth move, the edge still feels as it did at the start.

Where no thickness is given, it is worth asking. Anyone who does not state it usually has a reason.

Then: how the parts are connected

Joints are the point at which furniture fails in everyday use. A chair rarely breaks in the middle of a part; it wobbles at the joint.

With metal frames, the difference between welded and screwed is the single biggest difference in quality. A weld cannot work loose. A screwed joint moves under changing loads and sooner or later needs retightening. If a description only says "metal frame", asking about the type of joint is therefore justified.

With wood, an old rule applies: a screw into end grain does not hold permanently. There the thread grips the fibre ends instead of across the grain, and what sits firmly at first comes loose under load. Good constructions get around this with tenons, dowels, cross pieces or recessed fittings. Where table legs are visibly just butt-screwed on, wobbling is only a matter of time.

The same applies to threads in fibreboard. In MDF or chipboard, a thread grips properly once. Anyone who keeps turning during assembly until it "feels tight" strips the material, and the joint is ruined for good. Screws in fibreboard are therefore tightened until they are seated – and no further. More elaborate constructions use threaded inserts or metal sleeves at loaded points anyway, instead of screws directly in the board material.

With carcass furniture, the back panel determines the stability, even though nobody sees it. A grooved-in back panel sits in a groove in the sides and base and braces the entire carcass against distortion. A thin hardboard panel stapled on from behind does so only until the staples give way. A cabinet that twists when lifted almost always has a stapled-on back panel.

With woven seating – rattan, cane or paper cord – it is worth looking underneath. Weaving alone cannot carry weight for years without giving; it stretches and sags. If there is an additional seat support or a frame underneath that takes the load, the surface keeps its shape. Exposed screw heads in the middle of a woven surface, on the other hand, are rarely a good sign.

With upholstery: what lies beneath the cover

The cover is visible, the construction is not – and the construction determines whether an armchair is still comfortable after three years.

Ideally, there is a suspension system beneath the upholstery. Two types are classic: steel springs and elastic rubber webbing. Springs take up weight and return it in a controlled way; webbing gives and works more softly. Many well-built upholstered pieces combine both – springs where body weight acts at specific points, elastic webbing where give matters, for instance in the backrest.

A seat without suspension consists only of foam, and foam compacts. The first hollow then appears not after years but after months, and it does not come out again. Where a description is silent about the inside and names only the cover fabric, that is a clue in itself.

A second point is the density of the foam, given in kilograms per cubic metre. Higher values mean more material per volume and therefore slower sagging. This has nothing to do with firmness, which is described by the compression hardness. And one more detail: solid wooden armrests withstand considerably more than upholstered armrests over a fibreboard frame, because that is exactly where people pull when standing up.

Finally: the small parts

Glides, clips and feet show best whether someone has thought about the furniture in use, because that is where corners are most easily cut.

Stone tops on metal frames, for example, should be fixed and not just laid on – with clips, pins or a milled recess. Felt glides under metal feet cost almost nothing in production and prevent scratches in parquet. Height-adjustable glides compensate for an uneven floor in an older building, which would otherwise leave a table permanently rocking. All of these cost a few cents in manufacturing and prevent very real damage.

Then there are the fittings. A concealed hinge with soft-close can be readjusted in three axes when a door no longer closes flush after years. A simple surface-mounted hinge can only be corrected with new drill holes. A drawer on full-extension runners opens completely and carries more than a partial extension on plastic rollers. And anyone who pulls out a drawer and looks at the sides sees immediately whether it is dovetailed, dowelled or merely stapled.

When a manufacturer thinks ahead at this point, it has usually thought ahead at other points too.

What you can still check when buying online

Touching edges and knocking is not possible online. What is possible is reading the data sheet like a craftsman: is the type of construction named? Is a board thickness given? Is the construction described, or only the material? Is there a weight?

Weights are the underrated clue. Two sideboards of the same width, one of which weighs only half as much as the other, necessarily differ in material or in material thickness – and that cannot be glossed over. Solid wood weighs more than chipboard or fibreboard, a thick board more than a thin one, a solid carcass base more than a honeycomb core. Where weights are missing entirely, it is rarely an oversight.

One last checkpoint that costs nothing: the assembly instructions, if they can be viewed in advance. They show how many parts a piece of furniture consists of, how these are connected and whether metal connectors are used at loaded points. And they reveal whether a piece of furniture can be taken apart again for a later move without the joints wearing out in the process.

Frequently asked questions

How can you recognise good furniture quality?

By the edge finishing, the stated board thickness, the type of joints, the upholstery construction and details such as glides, fittings and clips.

What board thickness is good?

For solid table tops, a thickness of about 30 millimetres (1.2 in) or more is considered solid. What matters, however, is the relation to the span: the greater the distance between the support points, the thicker the board has to be. Where no thickness is given, it is worth asking.

Is welded better than screwed?

With metal frames, yes, because a welded joint cannot work loose. Screwed frames need occasional retightening.

What does steel spring suspension tell you about an armchair?

That there is a load-bearing layer beneath the foam. Without suspension, the seat consists only of foam, and that compacts over the years.

Why is weight an indication of quality?

Because the type and thickness of material are reflected in it. Missing weights more often conceal thin constructions than heavy ones.
