H2owmn's measurements work if you're placing the bed at the BACK of the trailer. I turned the dinette at the F'RONT into a permanent bed. I just went out and to find that the mattress provided in October last year measured 30" wide, 76" long, and 7" deep. (The mattress is quite a snug fit; I'd have preferred a mattress that's at least an inch smaller all around.) I added a 4" piece of the firmest foam my local distributor provided, topped it with a 3" piece of latex, and encased all in a zippered moisture-proof mattress protector. Most folks seem to sleep well on the mattress without enhancements, but the combination of fibromyalgia and arthritis have me exhibiting the "princess and the pea" syndrome. I sleep comfortably now. Just need a little stool to get in and out of it!
