This is a wonderful light-weight cover. Using king-sized comforter and duvet cover on my queen bed makes a BIG difference in the slippage issue, no problems at all! But it is just a light, wrinkle free cover that doesn't add weight to your sleep solution, especially if you like a "light" but warm comforter! Some other duvets are heavier cotton and look great, but do not offer the silky movement that this provides, I am very pleased with this duvet cover! Have been using it for a few months and am still impressed!
