The JL&C Upholstered Beech Wood Dining Chair is built from three materials chosen for what each one does best in a dining chair context. The frame is solid beech — a hardwood selected specifically for furniture production because of its high bending strength, consistent grain structure and excellent response to both steam bending and mortise-and-tenon joinery. Every frame joint is cut, fitted and assembled by hand in our Shanghai workshop. The leg-to-rail joints are mortise-and-tenon, reinforced at the corner blocks with structural adhesive — a construction method that resists the racking forces that dining chairs experience every time they are moved, angled or leant back against. This is the joinery that determines how long a dining chair remains stable in daily restaurant or residential use, and it is the part of the chair that is most frequently compromised in lower-grade production.

The seat and back are cushioned with high-resilience (HR) foam — a foam grade specified by density and ILD (Indentation Load Deflection) rating to maintain its original support and shape through tens of thousands of compression cycles. Unlike standard polyurethane foam, which progressively softens and loses its profile within months of regular use, HR foam retains its structural recovery rate across the lifespan of the chair. The seat cushion is built to a firm-to-medium density appropriate for a dining application: supportive enough for a two-hour meal, comfortable enough for an extended dining occasion, and resilient enough to hold its shape when the chair is not in use. The back cushion mirrors this specification, providing lumbar support without the excessive softness that causes the back panel to lose its shape under regular use.

Fabric upholstery is applied over the foam and frame by our in-house team of skilled upholsterers. The fabric palette covers 30+ colours and textures — from premium plain weaves and textured bouclés through to performance-grade fabrics with Martindale rub counts of 30,000 or higher, suitable for commercial dining environments. Custom fabric specifications — including client-supplied fabric, COM (Customer’s Own Material) — are accepted for residential and hospitality projects where the fabric must coordinate with a defined interior palette. All upholstery is applied with consistent tension, aligned seams and concealed fixings, and every chair is inspected before packaging to confirm that the fabric sits correctly on the frame with no pulling, wrinkling or misalignment.
