It took a long time to assemble the bed. The steps are clear but the hex key is not easy to use for fixing a bed. There is no bed board that comes with the package. Our original mattress is soft, so it would collapse in between. I need to buy an extra bed board and a new firm mattress for this bed. The standard twin mattress of 39'' by 74'' is too wide. It's difficult to find a suitable mattress for the slightly small dimension. I discover that this bed is only suitable for a person of 165lbs or below. My son, who is a teenager, is reaching the maximum limit soon. It'll be better if the website can state it clearly beforehand. We're using it now, instead of returning it. But, I foresee we cannot use it for a long time.
