How species selection affects the finished piece
The choice of timber determines how long a piece takes to build, how it looks when finished, how well it holds fixings, how it responds to seasonal humidity changes, and how much it costs. Many beginner woodworkers choose timber based on appearance alone and are surprised when a visually attractive but difficult species resists hand tools, blunts plane irons quickly, or develops cracks when the heating comes on in autumn.
The five species below are the most commonly available in Polish timber yards and furniture suppliers. Each is assessed on the same set of criteria: Janka hardness, workability with hand tools, grain character, finishing behaviour, dimensional stability, and approximate retail price per board metre (based on 2026 Warsaw prices for kiln-dried furniture-grade stock).
Oak (dąb)
Janka hardness: 1290 lbf. Oak is the reference hardwood in Polish furniture making and the most abundant domestic hardwood in central European forests. It is heavy, hard, and demands sharp tools — a dull plane leaves torn grain across the medullary rays. Quartersawn oak shows a distinctive silver-fleck figure from those rays; flatsawn oak shows a bolder cathedral grain.
Oak is moderately stable once kiln-dried but responds to humidity changes across the width of wide boards. For table tops wider than 400 mm, breadboard ends or frame-and-panel construction manage movement better than edge-glued slabs.
Finishing: oak takes oil, wax, and water-based lacquer well. It contains tannins that react with iron, leaving blue-black stains where metal clamps, screws, or tools contact wet glue or water — use plastic-tipped clamps during glue-up.
Price: 60–90 PLN per board metre (25 mm thick, 150 mm wide) for kiln-dried furniture-grade European oak.
Pine (sosna)
Janka hardness: 870 lbf. Pine is the most affordable and most available solid timber in Poland and covers the widest range of furniture projects. It planes, saws, and chisels easily, is light for its size, and takes paint or oil uniformly. The grain is straight with visible resin canals and prominent growth rings; knotty pine has a distinct rustic character that is either desirable or a problem depending on the project.
Pine dents easily under point loads — a key dropped on a pine table top leaves a mark that an oak top would not show. For heavily used surfaces (dining tables, workshop benches), hardwood is a better choice. For shelving, beds, and painted furniture, pine is practical and well-suited.
Stability: pine is less stable than oak across the width and benefits from acclimatisation in the room where it will be used for at least two days before cutting. Avoid timber purchased directly from outdoor stacks at a builders' merchant — the moisture content is often too high for furniture use and will cause movement after assembly.
Price: 18–30 PLN per board metre for kiln-dried furniture pine (25 mm × 150 mm).
Walnut (orzech)
Janka hardness: 1010 lbf. European walnut (Juglans regia) has a rich chocolate-brown heartwood with straight to slightly wavy grain and works beautifully with hand tools — it planes without tearing, takes a crisp edge on mortises and tenons, and finishes to a smooth surface with minimal effort. It is the material of choice for high-value furniture, gunstocks, and decorative turning.
The main limitation is price — walnut is three to four times more expensive than oak per board metre and significantly harder to source in wide widths. Most walnut in Polish suppliers is available as narrow slabs (80–120 mm wide) or at premium prices for wider boards. Edge-jointing narrow walnut boards to achieve a table top is common practice and results in an attractive alternating grain pattern.
Price: 120–180 PLN per board metre for kiln-dried walnut (25 mm × 100 mm).
Beech (buk)
Janka hardness: 1300 lbf. Beech is common in Polish forests and widely used for furniture legs, chair frames, workbench tops, and tool handles. Its grain is fine and even; the wood is pale cream to light tan with small fleck. It machines precisely, holds screws and dowels well, and is used extensively in factory furniture production precisely because of its predictable behaviour.
The significant drawback of beech is dimensional instability. It moves considerably with seasonal humidity changes — more than any other species on this list — and is not recommended for wide flat panels unless the construction method accounts for movement. Steamed beech (buk parowany) has a warmer pink-brown colour and is slightly more stable than unsteamed material; it is the standard for bent furniture components.
Price: 25–40 PLN per board metre for kiln-dried beech (25 mm × 100 mm).
Ash (jesion)
Janka hardness: 1320 lbf. Ash has a pale cream to light grey appearance with pronounced straight grain and exceptional toughness — it absorbs shock better than any other European hardwood, which is why it was the traditional wood for tool handles, sports equipment, and vehicle wheel spokes. For furniture, ash provides an alternative to oak at a similar price point with a lighter appearance and slightly more dramatic grain.
Ash works well with hand tools despite its hardness and finishes cleanly with oil or wax. It is available in wider boards than walnut and at prices close to oak. One consideration: ash fraxinus trees across central Europe have been affected by ash dieback (Hymenoscyphus fraxineus) since the mid-2010s, which has reduced the long-term timber supply and may affect price and availability in coming years.
Price: 55–80 PLN per board metre for kiln-dried ash (25 mm × 150 mm).
How to read a timber merchant's stock
Polish timber yards sell furniture-grade hardwood by the board metre (mb) for profiled stock and by the cubic metre (m³) for rough-sawn. Furniture boards are typically sold in standard thicknesses of 25 mm (5/4"), 32 mm, and 50 mm. Width varies per board. When calculating waste, add 15–20% for crosscut waste, rip waste, and unusable defects — more for knotty pine, less for premium clear-grade hardwood.
Moisture content for furniture use should be between 8–12%. Timber at 18–20% (typical for outdoor storage) will shrink, check, and warp in a heated interior. Most timber merchants can measure moisture content with a pin meter on request; if not, invest in a basic pin-type moisture meter (150–250 PLN) — it is one of the most useful instruments in a home workshop.
Summary comparison
For a first furniture project where the goal is learning rather than producing a showpiece: pine is the practical choice. For a piece that needs to last decades and take a clear natural finish: oak is the default. For decorative detail work or high-value pieces: walnut. For structural frames and components: beech, with an understanding of its movement. For an oak alternative with lighter colour: ash.
