MIL has just brought us one for £40 and I read conflicting things about how supportive etc they are. I'm probably wrong but I always think of them as being a bit cheap and nasty (apologies - not trying to offend anyone - ready to be proved wrong).
Any advice/comments on if a £40 foam cot mattress is likely to be of decent quality and very supportive (I'm a bit obsessed about wanting a firm spportive mattress for LO)?
