Milliard Cot 6-inch Tri-Folding Memory Foam Mattress with Washable Cover, (75"x31"x6")

Pros: Authentic memory foam, nice %26 thick, technically one piece, doubles as a cushion/seat, actually comfortable. Cons: The longest one for a 6'4" adult is still too short if you use a pillow but not manufacturer's fault, mattress design hasn't caught up with tall people needs yet. Over time ALL foams break down, flatten out, get misshapen and change color. This one is no exception in that it wasn't meant for all day use as a seat and all night use for sleeping, every day for years. It has misshapen a bit but not too bad. It is pretty colorful from being the main bed/chair of a teenage gamer and it's impossible to wash if you don't want to shred the foam getting the cover off/on. Take it outside if you have anything clean and strong enough to hold it or hang it. Mix Dawn dish soap and hydrogen peroxide into a spray bottle, spray until soaked or your hands give out. Hose off the whole thing but be CAREFUL to never use a stream to rinse as it will cut the foam when wet even through a cover.
