I bought this on Black Friday last year and it was delivered a couple of weeks later. Being in a northern climate it sat in my garage all winter. Since it comes in 3 large boxes, not including the slide which I had to stack on top, I was anxious to get started on it this spring. Well it finally got nice enough last weekend that I decided to bust into the boxes and see how long this project would take me. I started Friday evening after supper and got the monkey bars and ladder put together. Saturday morning I got started at about 9:00 a.m.. There are A LOT of pieces so my wife graciously offered to organize all the pieces by letter and in numerical order. This was a HUGE time saver. I worked for 10 hours that day and another 7 hours on Sunday with only breaks to charge my drill. A good cordless drill is a must! So total time was just under 20 hours including redoing a few steps since I had a board or two flipped, my fault though. This was done mostly myself. My wife did help for a few awkward parts but she had to chase around our 2 and a half year old son so she had her hands full. Overall the assembly went pretty smooth. I've put together play sets in the past helping co-workers and this seemed to go a lot smoother. Only 2 bolts were missing from the hardware kit which happened to be the two needed to attach the monkey bars. I emailed the manufacturer and they sent me the two missing parts in the mail the next day. As soon as they arrived it took me 5 minutes to wrap it all up. My son loves it and we are pleased with the quality. Would buy again.
