I ordered the full size because of the size I needed and the reviews that many said the top bars only fit a full size. It came in 3 different deliveries, so not delivered all at the same time. The bolts sent were not the correct size and some of the placement holes needed drilled a little more to make the bolts easier to attach and use.  (holes were a hair too small. Enough to make it very difficult to put them in) After a trip to the local hardware store; $20 extra in materials, 4 people and 2 hours labor, the bed is complete and looks nice. Sturdy.
