Available in single, double and kingsize, this mattress enhancer has been designed to add warmth to your bed during the winter. But that's not all: the microfibre reverse means it'll actually keep your bed cool in the summer, too. There are elasticated corner straps for a snug fit to any mattress kind, and it's machine washable – plus can be tumble-dried on a low heat setting. In a similar vein, the teddybear fitted sheet in teddybear mushroom – which is available in four bed sizes, FYI – makes for the dreamiest base to your bed. So good, in fact, that you'll never want to get up. It's super cosy, washes well at 30 degrees and is the perfect companion to one of the teddy fleece bedding sets pictured above. Teddybear bedding is an instant winter warmer which is guaranteed to elevate the cosiness-rating of your sleep-set up. Here's everything you need to know before investing.
