yes i have washed it at 40 before etc who you say but the piece i washed yesterday i'd not had long and well all the fluff on top kind of disintergrated and has dissapeard leaving mainly the backing and filling my washing machine with the top bit! Chucked it out and given my washing machine a good clean and now washing the cat blankets so just hope it's not broken the machine,

bit hard to describe how it went really.
