I was a little overwhelmed at first but after I actually got into the box, started to separate and identify the parts it went together very easily. I'm a 56 year old grandpa with pretty good mechanical skills and it probably didn't take me more than 12 hours (by myself) to completely finish the project. I built the majority of everything in my garage and only had to enlist the help of my son when we carried it out to the backyard for final placement and to attach the swing portion.  Parts were well marked and really only have a couple of suggestions on using different hardware in certain areas to help protect against splitting the wood, and pre drilling some holes to help as well.
