I am happy to find a purple grey set to go into the master bedroom. The backing/underside is a thin slippery polyester and the comforter slips down. It doesn't stay in place as it did with our old cotton duvet. colors are slightly darker than in the pictures. Buttons at the bottom for closure that are visible, would have perferred zipper or buttons that buttoned inside. Not the best quality, but suffices for the cost.
