Your duvets, pillows, protectors and toppers are used every night and over two and a half thousand hours every year. Our 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 our 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. When the night’s get colder, you can rest assured our 13.5 Tog duvet provides warmth in winter months for that added cosy feel so you can sleep soundly. 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. Our 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. Our 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. Our duvets are all UK standard sizes, so are a suitable fit for all standard beds and duvet covers:- Single: Length 200 cm x Width 135 cm; Double: Length 200 cm x Width 200 cm; King: Length 220 cm x Width 230 cm; Super King: Length 220 cm x Width 260 cm. Review: Exceptionally warm, comfortable, and great value for winter - purchased the Slumberdown Warm Winter Nights King Size Duvet (13.5 Tog) specifically for colder months, and it has been excellent. Warmth is exactly what you would expect from a 13.5 tog duvet. It keeps the bed comfortably warm on cold nights without feeling heavy or restrictive. The insulation is evenly distributed, so there are no cold spots, and it retains heat well throughout the night. Despite the warmth, the duvet is surprisingly comfortable and breathable. It doesn’t feel overly bulky, and it drapes nicely over the bed, making it easy to sleep under without feeling trapped or overheated. The quality is very good for the price. The outer fabric feels soft and smooth, and the stitching appears durable, holding the filling in place even after regular use. It fits a king size bed properly, with good coverage on both sides. Another plus is how easy it is to care for. It washes well and dries without losing its shape or loft, which makes it practical for everyday use. Overall, this is a reliable, cozy winter duvet that delivers exactly what it promises. If you’re looking for a warm, comfortable duvet for cold nights at a reasonable price, this is an excellent choice and easy to recommend.
