Has anyone ever washed a mattress cover? The Ikea Sultan one to be precise - it's quite old so I don't know if they still do this one, but its in good condition as only occasionally slept in by humans, but it's got a zip at one end and the website instructions say it's removeable and washable, but I was wondering how much of a faff it might be.
Said mattress has been subjected to a dirty protest by a stressed cat (thankfully not a tom) and could really do with a proper wash but am worried about it shrinking, getting all out of shape or being impossible to get back on. Although I do have a strong and practically minded DP to assist with this - it definitely looks like a two person job.
Should I go for it or leave well alone?
