They have it in pillows??
There are different kinds of Assy, some more harmful than others.
I doubt they would put any of the dangerous assy in it like the blue stuff - imagine the public outcry! ...Pillowgate!! ...all the slightly deranged Daily Mail reader types on the telly saying that they have banned their fat ugly kids from ever using pillows again ....the HSE having to give you a risk assessment every time you want to go to bed..... ....Pillow factories getting attacked and burned to the ground! (well ok, maybe not, but you know that I mean) ...PEOPLE WOULDN'T BE ABLE TO SLEEP AT NIGHT!! (Deliberate pun).
So, no, probably not. Now go out and buy a new pillow, but if you do develop mesothilyoma (spelling?) in about 30 years time, then give me a shout so I can update my reply!
