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.
