Query: Pretty Good Beds

Things I liked:Pretty lightweight, easy to move. Didn't take up too much space. Very comfortable night's sleep, at least that's what my nephews told me. Pretty sturdy, held my weight(about 220lbs) without a problem. I did not sleep on it, however. Packed and unpacked easily, and they fit nicely in a closet when not in use. Will probably take them on vacation, to use for kids when in smaller hotel rooms. (I bought two of them)Things I did not like:Little difficult to get the end rails on. I was afraid I might bend or break them when forcing them on, but got them on without bending or breaking. Still a little concerned that after repeated assembly/disassembly, I might not be so lucky. Black end caps on rails, that cover the sharp aluminum edges, fell out easily, and marred the walls. The black plastic left marks on the walls that I could not easily get off. Great for kids, but should be a little wider for a full-sized adult.
