My mum bought us duvets in the 60’s because she hated changing beds!! Widowed in her early 40,s with 3 of us and working full time! We were taught to change them from a fairly young age!! I now have a Coverless duvet! Was the whole thing !! Best thing I ever did!!Do you remember when duvets became the norm? Think that was the 80's too and going to Pizza Hut.
