When buying a duvet, the main things to consider are the outer and inner materials and to ensure the tog of the duvet is to your preference in regards to how warm you prefer to be when sleeping. Duvets with a cotton outer fabric are luxurious, breathable and more resistant to wear and tear, whereas polypropylene duvets are great value. Microfibre duvets are made via a complex manufacturing process to give a soft and smooth finish. In regards to your choice of filling, we sell duvets with a Duck feather & down filling which has increased thermal properties, or Hollow fibre filled duvets, which are light yet available in a range of togs to give the desired warmth. Tog Ratings range from 4.5 for a summer duvet, to 15 for an ideal duvet to keep you warm in the winter. Duvets which are 13.5 tog are considered suitable for use as an all year round duvet. All our duvets are available in Single, Double, King & Superking size.
