The bedframe was finally received (delivery company problems, not the manufacturer or Wayfair) a week after ordering it. It is heavy, but pretty simple to assemble. I put a 12" plush gel mattress on it (60 lbs) and I have laid on it (another 230 lbs). It didn't collapse under that test anyway. Since it is used as a spare bed, time will only tell if it will really hold up to more weight, plus movement. I do like the fact that the slats are steel and fit tightly within their holders, spaced about 6 inches apart. Aesthetically it works for me as a spare bedroom bed.
