Pick up my new little van this weekend. It's a Citroen Nemo. I'm gonna be a weekend/ festival camping\vangirl,so doing a very basic conversion on a blank canvas . I've got the insulation sorted. I would appreciate some advice please on mattresses. Would it be better to have a mattress made ( not cheap I know) or just go with some good deep memory foam cut to size and covered? I'm on a budget, but don't mind spending a bit more on bedding if I really need to. Many thanks in advance.
