{"ai_json_enabled":true,"answer":"Underlay changes comfort, acoustic performance, support and the way carpet wears, while installation controls joins, tension, edges, stairs and the finished level at doors. A good carpet over unsuitable underlay or poor preparation can feel disappointing and age prematurely, so compare the whole installed system rather than the face fibre alone. This category covers Woven and fitted stair runners, runner design, grip, pattern, colour, custom fitting and installation craftsmanship. Do not judge on softness alone. Fibre, pile construction, density, backing, roll width, underlay and installation all affect appearance, comfort, cleanability and long-term wear. There\u2019s no single \u2018best\u2019 carpet for a coastal-terrace stair runner\u2014choice depends on traffic, exposure to sand/salt and desired look. Durable fibres and tighter constructions withstand coastal wear better; wool provides warmth and resilience but synthetics can offer improved stain resistance and easier maintenance. Consider pile height (shorter pile generally safer on stairs), pattern scale to hide wear, and careful seam placement. Keep the exact product name, colour, batch details, written specification, care guide and warranty conditions with the final quote so future cleaning, repairs or replacement discussions refer to the carpet actually supplied.","answer_source":"grounded_carpet_fallback","category":"Stair Runners","category_slug":"stair-runners","confidence":"grounded_in_approved_carpet_sydney_context","conversation_depth":0,"conversation_followup_type":"","conversation_parent_slug":"","conversation_reason":"","conversation_root_slug":"","created_at":"2026-10-12T19:04:23+00:00","daily_publish_cap":2,"date_published":"2026-10-13","display_date":"2026-10-13","drip_batch":"2026-10-13","drip_status":"daily_auto_published","freshness_warning":"Products, colours, stock, pricing, installation timing and showroom details can change.
