The tufted, knitted fabric cover sits above a layer of 1000# microfiber and ventilated soft foam quilting, giving a breathable surface with a neat, tailored finish. Below this, a layer of support foam and cotton padding sit on top of the main spring core, a 22cm pocket spring unit made with 2.2mm wire that runs edge to edge for stable, extra firm support. The build is mirrored underneath with more cotton padding, foam quilting and a polyester fabric base. The materials used are hypoallergenic, and all our mattresses meet UK fire safety regulations. This is a one sided mattress and should not be turned over, though it can still be rotated head to toe for even wear.\u003c\/p\u003e","brand":"Fat Sofa","offers":[{"title":"Single","offer_id":58430206673280,"sku":"FSROCK30","price":220.0,"currency_code":"GBP","in_stock":true},{"title":"Small Double","offer_id":58430206706048,"sku":"FSROCK40","price":299.0,"currency_code":"GBP","in_stock":true},{"title":"Double","offer_id":58430206738816,"sku":"FSROCK46","price":299.0,"currency_code":"GBP","in_stock":true},{"title":"King","offer_id":58430206771584,"sku":"FSROCK50","price":339.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0928\/9619\/9040\/files\/Rock_3.jpg?v=1783794577","url":"https:\/\/fatsofa.co.uk\/products\/ortho-rock-28cm-extra-firm-orthopaedic-pocket-spring-mattress-4-sizes","provider":"Fat Sofa","version":"1.0","type":"link"}
