Assembly tip
As per other reviews, it is finicky to assemble the very final bar into position.
A tip: assemble it all as tightly as possible, including one end of the final bar. Then for the final connection, rotate the leg *away* so that when the bar is pulled as far over as possible, you can rotate the leg opening back down over it.
That way, you aren't trying to also wrestle the bar over the leg, the fabric is just too tight for that.
