Many retailers specialising in beds will have a mattress custom made for you.
We did that with our van as the supplied mattress was terrible.
Went in to 40 Winks in Perth, tried some until we found one we liked and they had one made to fit the van. We had previously measured up the size.
Not cheap though. You get what you pay for.
