No!!
We ended up going to our local mattress retailers and asking nicely (I took my teen with me) and they gave us three bags that did perfectly. We folded them up so they took up very little space, they weighed nothing and then we got them out the panniers at the airport. It was a triumph. No damage to the bikes either. (We just needed to buy tape).
They are wanting two.I've got three still in their packaging. Is it just the one?

Have you any bed shops near you?Hi do you have any more to sell? I ripped mine on a recent trip and my daughter would like one too. Mine was accepted on the trip out from London but on the return journey they insisted on a box. I was told it was to do with the airport scanner rather than the airline itself. Seems they don’t sell the bags anywhere now. I realise this is a very old thread I’m replying to.

The bags they use for the mattresses are similar to the bike bags.
If I can’t source a CTC bag then that will be the next option to try. At least I have plenty of time to sort something out, I just imagined the mattress bags to be even bigger, on my trip I optimistically carried the bag around with me hoping it would be acceptable on the way back. BA required a padded bag or box and the CTC bag combined with bubble wrap underneath around the derailleurs etc was fine. Coming back Vueling just said “well packed” but it was the airport rather than the airline that insisted on a box. It was good to learn that boxes can be bought at some airports though. I guess a mattress bag could be chucked away on arrival if I know I can buy a box for the return
