The duvets 200x200cm can be adapted to two ways of sleeping. They are more suitable for a single bed of 90x200cm or 90x190cm (teenager's bed). But they are also very suitable for a double bed 140x200cm if you do not want too much fallout of the quilt on each side of the bed. The duvets 200x200cm are declined in all ranges manufactured by Dumas Paris. This standard size is available in new duck down or new goose down. We encourage you to check the size of your duvet cover before placing an order. For the 200x200cm duvet, we offer several indications of warmth: winter duvet, summer duvet or tempered duvet. Choose the index most suited to the temperature of your room and how you sleep Whether you choose a synthetic duvet or a natural duvet, we can tailor a duvet to your exact dimensions, within 10 days. Duvets made to measure can not be returned. Lastly, you can request that your quilt, in standard or custom size, receive the exclusive GSD® process: it is a double jacket system, with a non-spotted anti-mite and anti-bacterial interior lining , which significantly reduces the risk of allergies.
