The independent pocket coil base provides responsive lift and reduces heat retention through open airflow channels, while the memory foam and sponge comfort strata absorb movement and target pressure points across the hips, shoulders, and knees. Because the comfort layers and support core are factory-bonded into one self-contained unit, setup requires zero tools or assembly—you simply unbox the mattress, place it directly onto a flat bed frame, and allow it to expand to its full 12-inch height before regular use.\u003c\/p\u003e \u003cp\u003eProduced without high-concern chemicals, the expanded foam layers minimize initial odor dispersion, keeping bedroom air quality stable during the first nights of use. At this exact thickness profile, the unit clears small gaps between wooden slats and sits flush on standard platform frames, preventing the sagging that occurs with thinner alternatives. Designed for primary bedrooms, guest rooms, or rental units, the hybrid layout delivers long-term durability without relying on separate box springs or conversion kits.\u003c\/p\u003e \u003ch3\u003eConstruction \u0026amp; Setup Facts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eHeight:\u003c\/b\u003e 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eFirmness Rating:\u003c\/b\u003e Medium-firm\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSupport Core:\u003c\/b\u003e Individual pocket springs\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eComfort Layers:\u003c\/b\u003e Memory foam and sponge\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eDelivery Configuration:\u003c\/b\u003e Self-contained roll\/cake, tool-free placement\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eChemical Profile:\u003c\/b\u003e Manufactured without high-concern substances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Journey Frog","offers":[{"title":"8 INCH \/ Twin \/ United States","offer_id":67491776593965,"sku":"14:-2;200007763:201336106;5:-5","price":126.99,"currency_code":"USD","in_stock":true},{"title":"10 INCH \/ Twin \/ United States","offer_id":67491776626733,"sku":"14:-3;200007763:201336106;5:-5","price":141.99,"currency_code":"USD","in_stock":true},{"title":"8 INCH \/ King \/ United States","offer_id":67491776659501,"sku":"14:-2;200007763:201336106;5:-3","price":228.99,"currency_code":"USD","in_stock":true},{"title":"8 INCH \/ Queen \/ United States","offer_id":67491776692269,"sku":"14:-2;200007763:201336106;5:-2","price":192.99,"currency_code":"USD","in_stock":true},{"title":"8 INCH \/ Full \/ United States","offer_id":67491776725037,"sku":"14:-2;200007763:201336106;5:-1","price":174.99,"currency_code":"USD","in_stock":true},{"title":"12 INCH \/ Twin \/ United States","offer_id":67491776757805,"sku":"14:-1;200007763:201336106;5:-5","price":153.99,"currency_code":"USD","in_stock":true},{"title":"10 INCH \/ King \/ United States","offer_id":67491776790573,"sku":"14:-3;200007763:201336106;5:-3","price":246.99,"currency_code":"USD","in_stock":true},{"title":"10 INCH \/ Queen \/ United States","offer_id":67491776823341,"sku":"14:-3;200007763:201336106;5:-2","price":211.99,"currency_code":"USD","in_stock":true},{"title":"10 INCH \/ Full \/ United States","offer_id":67491776856109,"sku":"14:-3;200007763:201336106;5:-1","price":195.99,"currency_code":"USD","in_stock":true},{"title":"14 INCH \/ Twin \/ United States","offer_id":67491776888877,"sku":"14:-4;200007763:201336106;5:-5","price":234.99,"currency_code":"USD","in_stock":true},{"title":"12 INCH \/ King \/ United States","offer_id":67491776921645,"sku":"14:-1;200007763:201336106;5:-3","price":263.99,"currency_code":"USD","in_stock":true},{"title":"12 INCH \/ Queen \/ United States","offer_id":67491776954413,"sku":"14:-1;200007763:201336106;5:-2","price":230.99,"currency_code":"USD","in_stock":true},{"title":"12 INCH \/ Full \/ United States","offer_id":67491776987181,"sku":"14:-1;200007763:201336106;5:-1","price":206.99,"currency_code":"USD","in_stock":true},{"title":"14 INCH \/ King \/ United States","offer_id":67491777019949,"sku":"14:-4;200007763:201336106;5:-3","price":355.99,"currency_code":"USD","in_stock":true},{"title":"14 INCH \/ Queen \/ United States","offer_id":67491777052717,"sku":"14:-4;200007763:201336106;5:-2","price":304.99,"currency_code":"USD","in_stock":true},{"title":"14 INCH \/ Full \/ United States","offer_id":67491777085485,"sku":"14:-4;200007763:201336106;5:-1","price":272.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/0544\/5165\/files\/Sfe40d9e3cc7042b4b4cf0b853a1b1e78K.webp?v=1788730179","url":"https:\/\/journeyfrog.com\/products\/12-inch-10inch-8inch-14inch-twin-full-queen-king-size-multiple-sizes-multilayer-hybrid-mattress-medium-firm-feel-ergonomic-design-with-memory-foam-and-pocket-spring-styles-available","provider":"Journey Frog","version":"1.0","type":"link"}
