Don't get me wrong. This is a good duvet set. So why the low score? Over the years I have experimented with high quality sheets and duvet covers. from 200 thread count to 1200. Higher is not always better. Why I went for the 800 count, was to try out the higher end, as the 1000 and 1200 are too thick for comfort, some describe them as cardboard like. Over the many years and this my final experiment, I think I have concluded that 450 - 600 is the range for the longevity and feel that I like and that there is value in getting long fibre single ply Egyptian cotton. Don't get me wrong in deepest winter you may want a heavy cover, but I would recommend a higher TOG rated duvet for that. Smooth, silky soft and moulding to your body is more important. Hope this helps. I must have spent thousands getting this knowledge. I now realise that a few expensive Italian (Frette) sheets are worth more than a lot of high thread count thick ones.
