We ordered the deluxe all seasons duvet set and was impressed as soon as it came out of the box. The set contains a thinner summer duvet and and slightly thicker autumn duvet which can be both safely and securely fastened together via poppers around the edges to create a winter duvet. Both duvets were considered thin (not airy or puffy like others) but had a good weight to them, and when under the covers they seem to hug both of us and fall more naturally (instead of creating a tent like effect between 2 people where the duvet is kept up in the middle forming a channel for cold air). We have the autumn duvet on at the moment and have to say it is proving to be a real treat. My partner and I prefer different temperatures in bed and this has really helped to balance different zones in the bed to both our liking's. Can't wait to try the combination of the 2 as we both like a weighty duvet and fell this will hug both of us even more. Thank you Thewoolroom, we would have never considered moving to a wool duvet had we not seen the website and read the testimonies and what wool could do. It worked.
