Shipped and arrived quickly. Each piece was thoughtfully marked on the bag, but then the bag had to be discarded, and there is no markings on the actual pieces. All the screws/bits/bolts are separated by the section you are putting together (a-frame, glider, slide, see-saw, swings, and trapeze). Instructions are very easy to follow. Overall, it took me 3 hours to assemble. Seems to be sturdy, and our daughter loves the set!
