Reflex foam, 2cm of memory foam and a copper-infused layer sit on top, under a bamboo knit cover.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eThe result is a medium feel with more give at the surface than a single-layer mattress, which suits side sleepers who want their shoulders and hips cushioned without losing support underneath. The pocket springs move independently, so movement stays on one side of the bed.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eAt 27cm deep it is a full-depth mattress for a standard bed frame or divan, and deeper than many standard fitted sheets allow, so check your sheet depth. It is made in the UK, meets BS 7177 for fire safety and arrives rolled and vacuum-packed. Give it a day or two after unrolling to reach its full shape.\u003c\/p\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eKey facts\u003c\/strong\u003e\u003c\/p\u003e\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeel:\u003c\/strong\u003e Medium (6 out of 10)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDepth:\u003c\/strong\u003e 27cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSprings:\u003c\/strong\u003e 1000 pocket springs, 18cm, with 2000 micro springs above\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComfort layers:\u003c\/strong\u003e Reflex foam, 2cm memory foam and a copper-infused layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCover:\u003c\/strong\u003e Bamboo stretch-knit, tape-edged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e Single 90 x 190cm, Small Double 120 x 190cm, Double 135 x 190cm, King 150 x 200cm, Super King 180 x 200cm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire safety:\u003c\/strong\u003e Meets BS 7177\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in:\u003c\/strong\u003e The UK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArrives:\u003c\/strong\u003e Rolled and vacuum-packed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery:\u003c\/strong\u003e Free to mainland UK, on the date you choose in your basket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGuarantee:\u003c\/strong\u003e 10-year manufacturer’s guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eWill it fit your bed?\u003c\/strong\u003e\u003c\/p\u003e\u003cp dir=\"ltr\"\u003eChoose the size your bed frame is made for: single 90 x 190cm, small double 120 x 190cm, double 135 x 190cm, king 150 x 200cm or super king 180 x 200cm.
