Amazingly comfy & cooler than memory foam, the Airstream® Topper will revolutionise your mattress comfort. The topper is a whopping 4.5cm thick so it’s deep enough to support your contours keeping you spine nice and straight. What’s more, it’s proven to be significantly cooler than memory foam thanks to Slumberdown’s clever Airstream® technology. So you’ll stay perfectly cool and comfy all night long. The luxury microfibre cover is wonderfully soft and cool to touch. Easy fit elasticated corner straps hold the topper firmly in place on the mattress no matter how much you wriggle around in bed. Plus it\'s made in the UK.
