Premium Solid White Ash Press-Curved Slat | 115 x 11.5 x 2.9 cm

The large seat standard: 115 x 11.5 x 2.9 cm of solid white ash. Where the 58.2 cm all-rounder covers compact frames, this size covers generous ones — dining chairs with wide seats, lounge seating, hospitality programmes where the seat board has to span without help and still look light.

What the dimensions mean

At 115 cm the board spans a large seat frame with no intermediate support. At 11.5 cm wide it presents a full seating face without the visual weight of the widest boards. At 2.9 cm thick it sits just under the 3 cm standard — enough section for a sitter across the span, light enough to keep a large chair movable. For programmes that standardise on one seat size, this is the dimension that does the most work.

Specifications

Where this size is used

• Large dining chairs — wide seats spanned without a centre rail.
• Lounge and hospitality seating — generous seats in daily-use programmes.
• Programme standardisation — one seat size across a collection.
• Reupholstery — replacement boards for large classic seats.

Why 2.9 cm and not 3.2

The half-millimetre matters less than the thinking behind it. At 115 cm, a 3.2 cm section adds visible thickness at the seat edge and weight in the chair; at 2.9 cm the board keeps a lighter profile while still holding a sitter across the span. For heavier contract use we would step up to 3.2 cm; for occasional seating, 2.9 cm is the better balance. Where your programme has a defined test standard, we confirm the section against it before tooling — and supply test samples so the choice is verified, not assumed.

Finishing and care

Ash’s open grain at 11.5 cm reads clearly under oil or clear lacquer, and stain penetrates evenly. For heavy-use seating, hard-wax oil gives a renewable surface; for commercial cleaning, lacquer seals the grain. Raw slats are sanded to 180 grit with the seat face ready for your finish schedule.

Frequently asked questions

Does a 115 cm span need support?

No — at 2.9 cm in ash it holds a sitter without intermediate support. For heavier loads we recommend stepping up to 3.2 cm.

Can it be matched to an existing seat board?

Yes — from a sample or dimensioned photo; curvature is verified against the form.

Is this size suitable for contract seating?

Yes, with the section confirmed against your test standard — we supply test samples before the run where required.

Can fixing points be machined?

Yes — drilled and countersunk points to your specification, machined before finishing.

Summary

115 x 11.5 x 2.9 cm of solid white ash — the large seat standard for generous frames, bent so the grain carries the load around the curve. Send your specification for a quotation within 24 hours; samples follow in 7–15 days.

Sizing at a glance

Programme notes

This size suits programmes that standardise: one seat dimension across a collection, ordered repeatedly, with the consistency that repeat ordering demands. Because the form is documented and the process locked, a re-order two years after the first batch produces the same board — which is what makes a standard size worth standardising on. Tooling records are kept on file, and the approved sample is retained for comparison.

For collections that mix seating sizes, this board pairs with the 58.2 cm all-rounder for compact frames and the 116 cm board for the largest — the three sizes cover most dining and lounge programmes between them.

Summary

115 x 11.5 x 2.9 cm of solid white ash — the large seat standard, at a section light enough to keep a big chair movable. Send your specification; we confirm the section against your test standard, quote within 24 hours, and deliver prototypes in 7–15 days.
