Am cross about this as the first time I washed this pillow cover, it disintegrated all over my machine. I washed it carefully, on its own and only at 40 degrees (says it can take 60 degrees).
I had a white blobby mess over the whole drum and rubber seal which I wasted loads of wipes trying to remove. Having removed all visible mess, i put on an empty load to rinse out the machine. Thinking it was fine I washed some sports kit and now the football socks are covered in these fucking hair like pieces of crappy pillow filing and some of the white blobby stuff that's reappeared 
. What can I do for my poor machine? I need to do loads of washing and cannot afford for clothing to get ruined.
The Ikea website says:
"The filling is held in place by the sewn channels in the cover, wash after wash." Bollocks why do they sell such crappy stuff. The pillow was £20 fgs.
