Hello there I'm selling this queen size inflatable mattress that has never been used. When we bought it we were planning on going camping and it just never happened. The air mattress went into storage and now I can't find the pump but any cheap pump will work. It's still in the original packaging and when I bought it I paid around $50 for the mattress so at $20 it's a good deal and the pump can be sourced easily and many will work. Thanks :)
