Heritage Interlock Contour Dining Chair
The Heritage Interlock Contour Dining Chair is a celebration of American furniture craft, blending a sculpted, supportive back with modern, all‑weather materials. Its contoured “interlock” backrest uses traditional mortise‑and‑tenon style joinery to create a puzzle‑like pattern that looks as refined as it feels, gently following the natural curve of your spine so dinners can stretch into long, easy conversations. Built from Starboard ST HDPE with stainless steel fasteners, it’s as at home on a covered porch or patio as it is around an indoor table—comfortable, resilient, and made to last.

Details & Craftsmanship
Care and Maintenance:
- Routine cleaning: Rinse with a hose, then wipe with mild soap and water. For tougher grime, use a non‑abrasive cleaner and a soft cloth or soft nylon brush. Avoid excessive scrubbing pressure to preserve the matte finish.
- Stain removal: For persistent stains, let a diluted bleach solution sit briefly, then rinse thoroughly. Citrus cleaner, isopropyl alcohol, or mineral spirits can help with grease and sunscreen; test in a small area first.
- Scratch care: Light surface scuffs can often be minimized with automotive silicone spray or furniture polish; do not use on walking surfaces. Deep gouges are cosmetic and do not affect performance.
- No refinishing required: Starboard ST is UV‑stabilized, color‑through material that won’t peel or flake, and it cannot be painted. Keep wood oils (e.g., teak oil) and wood stains away from the surface.
- Hardware check: Rinse salt and pollen periodically. Inspect 316 stainless fasteners seasonally; tighten if needed.
- Pressure washing: Safe when used at moderate pressure and distance; avoid aggressive tips held close to the surface.
- Seasonal care: No storage or sealing required. If storing, keep pieces clean and dry, and avoid heat above 180°F.
- General setup: Place on level surfaces to reduce uneven wear on rocker rails or feet. Lift to move—don’t drag across abrasive concrete.
