I read the reviews about this folding bed. It is very low to the floor. Thin mattress. It does fold. It has wheels. There is a metal latch to hold the folded mattress together. The bed is too low for older people.  Too close to the floor. Mattress is very thin.   I am shopping for a strong foam topper to make the bed taller and more comfortable.  Very probably put blocks under the bed to make it higher. It does fold. One reason to buy this bed was that it folded and could be stored when not in use.
