The extra-wide slat: 47.5 x 18.2 x 2.2 cm of solid white ash — the widest board in our range. Width is the whole point of this size. Where other slats present a line, this one presents a surface: a statement seat board, a small curved panel, a shelf front. At 2.2 cm thick it is a surface element rather than a support, and it bends to a pronounced curve precisely because the section is thin.
What the dimensions mean
At 18.2 cm wide this board reads as a panel, not a slat — the visual weight of a solid wood surface across a compact 47.5 cm length. The 2.2 cm section keeps it light enough to bend to a deep curve and light enough to handle in assembly, but it is not a load-bearing seat: for seating that carries weight, the 3 cm and thicker sections are the right choice. What this size does uniquely is give a curved solid-wood surface at a width that makes the curve the feature.

Where this size is used
- Statement seat boards — one wide board instead of several narrow slats.
- Curved panels and shelf fronts — a solid-wood surface with a pronounced curve.
- Back panels — wide curved elements on contemporary seating.
- Display and interior work — small curved surfaces for retail and styling.
The trade-off at this width
Width and curve depth trade against each other: a wider board needs a more generous radius at the same section, because the outside of the curve has further to travel. At 18.2 cm and 2.2 cm this slat takes a moderate curve comfortably; a tighter radius at this width would need either a thinner section or lamination. Where the design wants both width and a tight curve, we quote the laminated alternative — and the visual result is close to identical.
Finishing and care
At this width the grain is the design. Ash’s open grain reads clearly under oil or a clear lacquer, and stain penetrates evenly from pale to dark — both finishes suit a surface element that will be seen more than loaded. Edges are eased to your specification; on a wide board the edge profile is more visible than on a narrow slat.
Frequently asked questions
Is this wide enough for a seat?
It presents a full seating face, but at 2.2 cm it is a light-duty or occasional-use board. For dining or contract seating, use a 3 cm or thicker section.
Can it be made wider?
Yes — widths are made to spec; 18.2 cm is the widest standard size.
What radius can this width and section reach?
A moderate curve comfortably; tighter radii need a thinner section or lamination. Send the drawing and we will confirm.
Can several boards be matched for one seat?
Yes — colour and grain matched across the boards that make up one visible surface.
Summary
47.5 x 18.2 x 2.2 cm of solid white ash — the widest board in the range, for curved surfaces where the width is the design. Send the drawing with your radius; we confirm feasibility, quote within 24 hours, and deliver prototypes in 7–15 days.

| Width | 18.2 cm — the widest board in the range |
| Section | 2.2 cm — thin; deep curves, light duty |
| Primary use | Statement seat boards, curved panels, shelf fronts |
| Load class | Light — surface element, not a support |
Programme notes
A wide board is a yield question as much as a bending one: an 18.2 cm blank has to be cut from wider stock, and the wider the board the more care the blank selection needs, because grain that runs out toward one face shows immediately across a wide face. Blanks for this size are selected accordingly, and the colour and grain are matched across the boards that make up one visible surface.
For programmes using this board as a seat, the honest guidance is light duty — occasional seating, display, or programmes where the look matters more than the cycle count. Where the design needs both width and load capacity, we quote the laminated alternative, which reaches the same visual result at any section.
Summary
47.5 x 18.2 x 2.2 cm of solid white ash — the widest curved surface in the range, for designs where the width is the point. Send the drawing with your radius; we confirm feasibility, quote within 24 hours, and deliver prototypes in 7–15 days.
