We were in Fresno, CA a couple years ago, and were desperately needing a new mattress, RV King with radius corners, and about 8 inches thick. We visited this store/factory and the owner suggested laying on their latex foam mattress in the store and we were hooked. He made it with a firm 4 inch core and 2 inch softer foam on both sides and with the radius corners, and it's able to be flipped, unlike most RV mattresses. He even delivered it to our RV park, removed the old mattress and installed it into our rig. It is much lighter than the inner spring RV mattress that our rig came with, and the bed stays up without the help of a broom handle like the old mattress needed. We have been very happy with it. He even said if anybody we knew needed a mattress made for their RV, they could call ahead so they had the materials on hand, and they could make a new one in less than a day and he has parking for an RV in the rear of the business. We have no interest in this business, except being happy customers. https://abetterbed.com/
