Both my dc have pretty cheap mattresses that came with their cabin beds about 3 years ago. My eldest (and therefore heavier) complains that the mattress is uncomfortable now and it's probably about time that we bought something better for both of them. I have absolutely no idea where to start though!
Has anyone got any recommendations or tips of good buys or what to look for? And what's a reasonable amount to spend, we really don't want to spend too much as money is tight right now!
