We need to replace an old mattress for a perfectly good sofabed. My DP says he's looked online to find a company which just supplies mattresses but can't find one to fit. It's non-standard apparently. Haven't had time to look myself, tbh.
Has anyone replaced theirs? Where did you go? Should we just look for some thick foam and cover it with ticking? Not sure if this option would last though.
Your thoughts appreciated!
