Furniture descriptions mix material terms, construction details, timber grades, certification claims and marketing language. They do not all measure the same thing. Use this glossary to identify what a term describes and what information you still need about the exact product.
Start with the living room furniture range, then read individual specifications. A glossary explains terminology; it cannot establish the quality, lifespan or certification of every item in a collection.
The photograph is illustrative. It does not verify a product’s hidden materials, joints, grade, coating or certification.
Material terms
| Term | Meaning and buying check |
|---|---|
| Solid wood / solid oak | A material description for the parts made from wood in its solid form. Ask which species and components it covers; do not assume every back, shelf or drawer bottom is the same material. |
| Hardwood / softwood | Botanical groupings, not direct hardness measurements or finished-furniture quality grades. Ask for the actual species and component specification. |
| Oak | A group of wood species. Clarify whether the product uses solid oak, real-oak veneer, an oak-colour coating or a combination. |
| Real-wood veneer | A thin layer of real wood attached to a substrate. It is not a printed wood-effect surface. Request the core, edge construction and finish details rather than a universal thickness or lifespan rule. |
| Substrate / core | The material supporting a surface layer. Its grade, thickness, bonding and intended use matter; a veneer label does not identify the core. |
| Plywood | A panel built from bonded wood veneers, commonly with adjacent layers’ grain directions crossing. Ask for the specification rather than assuming every plywood panel is superior to every other board. |
| MDF / particleboard | Wood-based boards made from fibres or particles with binders. Ask for the exact board, thickness, edge treatment and application; the category does not establish a fixed service life. |
Construction and hardware terms
| Term | Meaning and buying check |
|---|---|
| Joinery | The way components are connected, potentially using shaped joints, glue and fixings. A joint name does not certify the entire piece. |
| Dovetail joint | Interlocking pins and tails, often used at drawer corners. Check where it is used; it is not proof of hand cutting or decades of guaranteed operation. |
| Mortise and tenon | A projecting tenon fitting into a mortise in another component. Suitability depends on design and execution, not the name alone. |
| Dowel joint / butt joint | Connections using pins or meeting board surfaces, with appropriate glue or fixings. Do not assign a quality tier or lifespan without the product design and specification. |
| Frame-and-panel | A frame surrounding a panel. The panel may use solid or engineered materials. Ask how movement is accommodated; the method does not make a piece immune to damage. |
| Hardware | Hinges, runners, catches, locks and other fittings. Ask which system is used and how it is maintained. Material, colour or heaviness alone does not establish reliability. |
| Full extension / soft-close | Drawer travel and final closing action respectively. They are separate features; neither establishes a safe load or a child-safety guarantee. |
| Load rating | A permitted load under specified conditions. Identify whether the figure applies to the top, shelf, drawer or complete item, and follow the stated conditions. |
Use only features specified for the model you are considering. Ask for usable internal dimensions, access openings, load limits and assembly or wall-restraint instructions. Do not carry out lifting, pressure or improvised load tests to verify a glossary claim.
Finish and process terms
| Term | Meaning and buying check |
|---|---|
| Varnish / lacquer | Coating terms covering different formulations and performance. Ask for the supplied finish and its care requirements; neither name establishes a coat count or a 20–30-year guarantee. |
| Eggshell | A paint sheen description, commonly low or mid sheen depending on the product. It is not automatically semi-gloss and does not define one universal coating system. |
| Chalk-style paint | A paint formulation associated with particular application and protective-finish instructions. It is not restricted to distressed looks; follow the exact maker’s instructions. |
| Oil finish / Danish oil | Wood-finishing names whose formulations vary. Danish-oil products can use oils and other ingredients such as resins. Do not infer a universal yearly maintenance schedule or substitute another product without guidance. |
| Wax | A surface treatment that may change sheen and require maintenance. Ask about compatibility and care; it is not automatically the best protection for every application. |
| Hand-finished / machine-finished | Process descriptions, not automatic quality grades. Ask what was done and assess the supplied result against its description. |
| Distressed / character finish | An intentional appearance. Confirm which marks are part of the agreed look and which damage or faults are not. |
A paint maker provides instructions for a smooth modern chalk-paint finish. This corrects a general misconception; it does not identify an Oak Castle coating or approve that system for your furniture.
Drying and natural-character terms
| Term | Meaning and buying check |
|---|---|
| Kiln-dried | Dried in a controlled kiln. It does not make timber immune to later moisture changes or prove that air-dried timber is unsuitable. |
| Moisture content | A measurement of water in wood. Ask about the method and relevant conditions; a single percentage is not a universal finished-furniture quality score. |
| Grain direction / variation | The orientation and natural appearance of wood. Both design and material behaviour matter; a particular grain pattern does not prove construction quality. |
| Knots / character marks | Features associated with natural growth or the intended look. Acceptability depends on condition, placement and the stated grade or appearance specification—not a blanket “never a defect” rule. |
| Spalting | Colour or pattern changes associated with fungal activity. It can be decorative, but advanced decay can reduce strength. Ask whether the material is sound and appropriate for its intended role. |
Timber grades are not universal furniture grades
Names such as Grade A, Grade B, Grade C, prime, select, furniture grade and cabinet grade require a named system or supplier specification. Do not assume that they form one universal ladder for completed furniture or that knot counts automatically map to those letters.
For example, American hardwood lumber grading uses defined NHLA grades such as FAS, Selects and Common grades. These concern the clear cuttings obtainable from sawn boards, not a warranty or service-life grade for a finished sideboard. Other materials and regions use different specifications.
Ask who assigned the grade, which standard or rules apply, what it measures and which component it covers. Appearance selection, structural assessment and finished-product workmanship should not be treated as interchangeable.
Understand the scope of certification claims
FSC and PEFC labels concern defined forest-based material sourcing and supply-chain claims. They do not automatically certify drawer operation, furniture load capacity or a guaranteed lifespan. Ask whether a claim applies to the product, a component or its packaging.
FSC explains its 100%, Mix and Recycled labels; Mix can include certified, recycled and controlled material. PEFC explains its certified and recycled labels. Check the exact label and applicable evidence rather than reading every certification as “all wood comes directly from certified forests”.
Environmental product labels, including EU Ecolabel or Blue Angel, use scheme- and product-specific criteria. Ask for the exact product claim and supporting record. The appearance of a logo or a general retailer statement is not a substitute for verifying its scope.
Turn a term into a useful question
- Which parts does this material, joint, finish or grade description cover?
- What standard, product data or certification evidence supports the claim?
- What are the actual dimensions, hardware features, load limits and care requirements?
- Are any descriptions inconsistent, and can the maker clarify them in writing?
Read our materials and construction guide for product checks, and use the buying-confidence checklist to record the answers. Then compare the living room collection on documented suitability—not a broad quality label.
