I really love the good sleep I am having under my new deluxe all season wool duvet and ordered this one because I feel the cold most of the year round. I am very disappointed though that after a few nights on the bed nearly all the poppers holding the 2 duvets together have come undone and the top duvet migrates to the middle of the bed. I have to spend time every day reaching back inside the duvet cover to straighten everything out and re-attach the poppers, which is driving me nuts. I think I will have to do some sewing to fix this but not what I'd hoped for after such an investment. Please start making duvets with more reliable fixings or even better a warmer winter duvet that isn't in 2 halves!
