I just changed the mattress in mine, it too is a queen short. I went to walmart.com
and bought the "bed in a box" for $210 with free shipping. It is an 8 inch thick foam mattress (5 inches regular foam and 3 inches of memory foam), it's a little firm but way better than the one that was in there. The cover is zippered so I can cut the foam to the right length. I left it long for now but it is a pain to squeeze around.
