Ran into a snag but fixed it. The side rails are to slide into  each other but the instructions have you attaching each end to the headboard  footboard first then you slide together. The problem was the bar was off  slanted and I couldn’t “fit” or slide them together …so I unattached the bars from the footboard then slid them in and it worked. Also one screw wouldn’t tighten but an extra screw was included and it worked. Overall seems solid. No squeaks. Took me an hour to put together. Good instructions and everything labelled.
