We are thoroughly confused and not sure which one to go for. We have the cot from m&p (second hand) and want to go to m&p to mattress only as the cot is a few years old and, although m&p claim the mattress/cot sizes haven't ever changed, their measurements just don't quite seem to fit the cot, so at least if we stick with m&p they can't complain if we need to return etc.
Anyone used any mattresses from m&p and would recommend/avoid their specific model? We want one to last the full way with our LO so needs a good 2 or so years life from it and we need to get a size 300 if that means anything to you.
