If your sleeping pattern is all over the place at the moment, then it might be worth paying attention to the kind of duvet you're using. If you often have disturbed sleep, waking up hot and sweaty, then it might be time to think about swapping your duvet for a lower tog. For hot sleepers, switching to a summer duvet with a lower tog can instantly make a difference to the quality of your sleep, keeping you cosy without overheating. Luckily, Amazon has the perfect deal for hot sleepers as the site has just slashed the price of the bestselling Slumberdown Anti Allergy 4.5 Tog Summer Duvet. Now on sale for just £13.18, it's a brilliant bedding bargain.
