We have to agree with Bears Den, we loved our Zinus 8” short Queen from Amazon in our camper so much that we moved it to our house Master bed during the Winter months while our camper was being stored and, when Spring came, we put it back in the camper and ordered a 10” Zinus regular Queen for our house Master bed! 18 months later and we still love both, especially when you consider how much you get for the price.
Like Bears Den said, be sure you don’t open the bag until it’s laying on the camper bed base, plus be sure to let it expand for at least 48 hours before using, preferably with some ventilation.
