INSTANT UPGRADE FOR YOUR MATTRESS - Turn a firm, old or uncomfortable single mattress into a supportive, cushioned sleep surface, no new mattress required. This 5cm gel memory foam topper adds an instant layer of pressure-relieving comfort. COOLING GEL-INFUSED MEMORY FOAM - CentiPUR certified memory foam infused with cooling Niva gel that draws heat away as you sleep, helping you stay comfortable instead of waking up too hot. PRESSURE RELIEF WHERE YOU NEED IT - Contours to your body to ease pressure on your hips, shoulders and lower back, cushioning the points that usually take the strain on a firmer mattress. CERTIPUR-CERTIFIED FOR CLEANER SLEEP - Not only is our topper hypoallergenic, but Independently tested and certified free from harsh chemical flame retardants, so you can trust what's inside your topper as much as how it feels. BACKED BY A 2-YEAR GUARANTEE - Slumberdown backs this topper with a 2-year guarantee, giving you real peace of mind on top of a better night's sleep. A NOTE ON THAT NEW-FOAM SMELL - Like all good quality memory foam, it arrives with a mild scent fresh out of the packaging. Unroll it and air it in a well-ventilated room for a day or two before use, and it'll settle right down. SECURE ELASTICATED STRAPS - Strong elasticated corner straps hold the topper firmly in place on your mattress, so it won't shift or bunch overnight. MADE IN THE UK - Proudly made in Britain, not shipped in from a cut-price overseas factory, because where and how it's made matters as much as what it's made from. REAL SLEEP MATTERS - Customers consistently tell us they sleep cooler and wake with fewer aches once this topper's on the bed. Real sleep matters - this is a simple way to get more of it. REMOVABLE, MACHINE WASHABLE COVER - The knitted cover with breathable mesh panels lifts off and washes at 40°C, so keeping it fresh is as simple as doing the laundry.
