Our multi-layer hybrid design balances high-density comfort foam with a heavy-duty spring base to provide a stable, \"hotel-grade\" sleep surface. It’s the perfect size for standard Full frames, offering 16 inches of extra width over a Twin for complete freedom to move.\u003c\/li\u003e\n\u003cli\u003e【Multi-Stage Physical Cooling—No Gels】Most \"cooling gels\" are just marketing gimmicks that trap heat after an hour. Our multi-layer design uses breathable, open-cell foam layers that work like a vertical ventilation system. Combined with the hollow core of our pocket springs, it creates a \"chimney effect\" that constantly cycles fresh air through the mattress. Stay cool through pure physics, not synthetic chemicals.\u003c\/li\u003e\n\u003cli\u003e【5-Zone Targeted Spinal Alignment】Stop waking up with that \"sinking into quicksand\" feeling. Within our multi-layer stack, we’ve integrated a targeted 5-zone coil system. It provides firmer resistance under your lower back while remaining plush under your shoulders. This anatomical alignment soothes morning stiffness and back tension, making it the ideal choice for side, back, and stomach sleepers under 6'0\".\u003c\/li\u003e\n\u003cli\u003e【Motion Isolation \u0026amp; 200lb Edge Support】Share your bed without the bounce. Each individual pocket coil reacts independently to weight, creating a \"silent zone\" that absorbs movement from partners or pets. Unlike cheap foam beds that collapse at the sides, our reinforced edge support handles up to 200lb, providing a stable surface for sitting or sleeping right up to the very edge.\u003c\/li\u003e\n\u003cli\u003e【Fiberglass-Free \u0026amp; Clean Sleep Standard】Your safety is built into every layer. This mattress is 100% Fiberglass-Free and crafted with CertiPUR-US certified foams. No harsh chemical odors, no hidden irritants. Delivered as a bed in a box, it’s a hassle-free upgrade for slatted frames, box springs, or electric adjustable beds. Includes a 100-night risk-free trial.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003eOverview\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eBrand : Coolvie\u003c\/li\u003e\n\u003cli\u003eSize : Full\u003c\/li\u003e\n\u003cli\u003eProduct Dimensions : 75\"L x 54\"W x 12\"Th\u003c\/li\u003e\n\u003cli\u003eItem Firmness Description : Medium\u003c\/li\u003e\n\u003cli\u003eTop Style : Euro Top\u003c\/li\u003e\n\u003cli\u003eCover Material : Breathable Knitted Fabric\u003c\/li\u003e\n\u003cli\u003eNumber of Layers : 3\u003c\/li\u003e\n\u003cli\u003eFill Material : High Density Foam, Pocket Spring\u003c\/li\u003e\n\u003cli\u003eWeight Limit : 200 Pounds\u003c\/li\u003e\n\u003cli\u003eSpecial Feature : 5-Zone Lumbar Support, Guest Room Essential \u0026amp; Teen Bed Upgrade, High-Density Multi-Layer Hybrid (Heavy Duty), Physical Airflow \/ No Chemical Gels, Zero Motion Transfer (Partner Undisturbed)\n5-Zone Lumbar Support, Guest Room Essential \u0026amp; Teen Bed Upgrade, High-Density Multi-Layer Hybrid (Heavy Duty), Physical Airflow \/ No Chemical Gels,… See more\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"COOLVIE","offers":[{"title":"Default Title","offer_id":47339202281650,"sku":"B0GRV5TF8W","price":543.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/8352\/7858\/files\/71bfP5BCSZL._AC_SX679_9714d544-b2f2-4772-ba87-6f8f02040e3f.jpg?v=1777021572","url":"https:\/\/casa-ment.com\/products\/b0grv5tf8w","provider":"CASAMENT","version":"1.0","type":"link"}
