need improvement on design

this weighted comforter is not too heavy at first even at a study 30 lbs. Over a king size bed, it distributes the weight fairly evenly. The issue and reason for the low rating is the comforter is actually a comforter and a duvet cover. There is no way to connect the cover to the comforter which leads to the weight of the blanket falling to one area in the cover which becomes quite heavy. The actual comforter had tabs to attach to something but the cover had nothing. Not even ties at the bottom
