Mattress Cleaning - How Much Is It?

[NannyPlumIsMyMum]

Hi all, I really need to get my mattress cleaned professionally . Does anybody have an idea of how much it costs please? We have a king size bed. Thankyou :-)

I just did a google search, and there's a London company quoting £55, but I don't know if that's just for a single bed. There seem to be lots of companies that are willing to give quotes, so maybe just ring around?
