Our summer duvet has a hollowfibre polyester filling with even distribution set across a straight channel pattern, which ensures the duvet never feels top or bottom heavy. The cover is a 50-50 polyester-cotton blend for comfort and durability. Even though the materials are naturally hypoallergenic, we have gone one step further by treating the duvet for anti-allergy, anti-mite and for superior hygiene. Every NightComfort product is made from start to finish by our experienced team in-house design sourcing and weaving the fabric producing the bedding and adding those finishing touches, all to the highest standard. We have been manufacturing and selling bedding from our production factories overseas and our headquarters in the north of England for over 40 years.
