## Description

Product Description At Slumberdown, we believe every body deserves a better night’s sleep and the power of great bedding can get your there. Your duvets, pillows, protectors and toppers are used every night and over two and a half thousand hours every year. Slumberdown range of products caters for every body and can help you gently drift off to sleep and wake up feeling refreshed. Slumberdown, better sleep for every body. A duvet’s thickness and warmth level can determine how well you sleep at night, that’s why Slumberdown duvets are designed in a range of Tog ratings, fillings and a choice of sizes so you can tailor your comfort to your sleeping needs. Most people use a 10.5 Tog duvet to help with a balanced comforting night’s sleep all year round, making it a great choice for the family. To make sure you’re comfortable, we’ve designed a king size duvet to fit a standard king size bed, giving those who like a little extra room the perfect space to relax with just the right amount of drape. Slumberdown duvets are made with a soft hollow fibre filling that surround you with a cosy comfy feeling so you can enjoy great night’s sleep all night long. Slumberdown soft touch cover has a smooth finish, so you can feel cosy and comfy, when snuggling into bed to enjoy a great night’s sleep and wake up feeling refreshed. We want to make life easier for you, that’s why this product is washing machine and tumble drier friendly, so it can be back on your bed as quickly as you need it. What's a tog? Duvets are available in a variety of "togs". Togs tell you how warm you will be when sleeping under the duvet. The lower the tog, the cooler you'll be. So you need a lower tog for Summer (4.5 tog) and a higher tog in Winter (13.5 or 15 tog). If you prefer to stick to just one duvet all year round choose a tog rating of around 10.5. Choose low togs for young children as they get warmer quicker than adults and older children. Slumberdown duvets are all UK standard sizes, so are a suitable fit for all standard beds and duvet covers:- Single: Length 200cm x Width 135cm; Double: Length 200cm x Width 200cm; King: Length 220cm x Width 225 cm; Super King: Length 220 cm x Width 260 cm. Set Contains: one duvet
