I bought this duvet in the hope that it would improve my sleep disturbances from menopausal hot flushes. Unfortunately, like many duvets that are advertised for this purpose I felt that I still experienced the heat I emitted getting caught between me and the duvet so that I felt I was trapped in radiated heat. A shame that this wasn't the duvet for me personally but excellent service in that the return process was flawless and a full refund without any delivery costs quickly arranged.
