Hello! I need a custom mattress for an old french bed. Will start off as a floor bed for a one year old (and me, let’s be honest, as we co-sleep most nights 🙄) and eventually go in a bed frame we have in the attic. Looking for recommendations for a custom mattress under £200, ideally that’s really like the Ikea one we have on our bed (I think it might be a hovag?)
