It took 3 hours to assemble with 2 adults. Hardware was packaged by item it belonged to and all items were well labeled. Recommendation is 3 to 8 years and up to 100 pounds. My 80 pound 8 year old grandson is really to big for the set. My 2 1/2 year old grand daughter is just right. At 3 it will be a perfect set for her. I thought the slide was a bit flimsy when I first opened the package and saw it but once assembled it is fine for her.  The ladder for the slide is set just under the top of slide. Grand daughter has learned to watch her head as she climbs up. As she gets bigger this probably won't be an issue. In the end, great deal for the price and she should get a couple of years fun out of it.
