A queen size memory foam mattress, 8 inches thick., Plus a cooling gel foam topper, Queen size and 3 inches thick. ........ Both are about six years old. I tend to sleep hot so both have some sweat stains, and other miscellaneous spots. but there are no urine stains. The covers for both can be removed and laundered, The gel foam topper was a king size; I cut it down to fit a queen and hand sewed it back together, not pretty but functional. The gel foam really is quite a bit cooler than the regular memory foam. These are definitely not pretty, the foam sags a bit, but they will work if you really need a free mattress or you have some other use to put the foam to. You will need help to carry them.
