I have received two sets of mattresses from Royal that have been of awful quality. I understand they do not make the mattresses, but they do sell them. I even went to a more expensive mattress thinking that would help, but it didn't. I am trying to contact the store to let them know it has been less than a month and this mattress is rolling up in the middle too. (Pillow Top Extra Firm $1000). A piece of junk.
