{"ai_json_enabled":true,"answer":"No. Thickness by itself is not a reliable measure of underlay quality or suitability. A better comparison looks at density, resilience, construction, intended traffic level, the carpet manufacturer's requirements, acoustic and thermal performance, relevant testing and the way the underlay behaves under load. A very soft or thick product can feel impressive in a sample but may not be the right support for every carpet, staircase or commercial application. The underlay should be selected as part of the complete flooring system rather than as a separate comfort upgrade.","answer_source":"prospect_knowledge_airstep_dunlop","category":"Underlay, Comfort & Sound Reduction","category_slug":"underlay-comfort-sound-reduction","created_at":"2026-09-07T02:43:58+00:00","date_published":"2026-09-07","display_date":"2026-09-07","id":"drip-20260907-d8ea9ab5","image_ids":["bcc-gen-013","bcc-real-004","bcc-real-009"],"image_url":"","last_updated":"2026-09-07T02:43:58+00:00","local_cache_status":"manual_knowledge_expansion","publish_status":"published","published":true,"published_at":"2026-09-07T02:43:58+00:00","question":"Is thicker carpet underlay always better, and what should I compare instead?","question_intent":"underlay_product_and_buying_guidance","rss_enabled":true,"rss_pub_date":"Mon, 07 Sep 2026 02:43:58 GMT","scheduled_for":"2026-09-07T02:43:58+00:00","schema_enabled":true,"site_key":"british-carpet-company","slug":"is-thicker-carpet-underlay-always-better-and-what-should-i-compare-instead","source":"manual_underlay_knowledge_expansion","source_record_ids":[],"source_type":"manual_underlay_knowledge_expansion","source_urls":[],"status":"active","tags":["underlay","density","thickness","resilience","buying guide","performance"],"updated_at":"2026-09-07T02:43:58+00:00"}
