Query: awesome nights sleep

Purchased this cot for a week long campout in Washington DC. very comfortable, able to change position without feeling like I was falling off. Slept very well the whole week, no backaches, no stiffness, well rested. The only negative is that initially it is very difficult to assemble. The first time was a struggle to fit the legs in, but I kept it together for a week and took a nap on it daily. The fabric and legs loosened up and came apart easily and went back together easily. Could be happier. Too bad it will be closed out.
