It took my husband and I about two hours to build and that includes him reading all the instructions and us laying all the parts out. All the bolts and washers and hardware are included. The wood makes it a classic for kids.  It is extremely important to anchor it. Once it is anchored down, I felt safe enough to sit on the slide and climb to the top. My kids, 5 and 7 year olds, love it. They spend a great amount of time playing with the swing and climbing the wall. It is very sturdy once installed in. I am glad for this set. I don't have to drive them to the playground to play for 15 minutes when the drive is 20 minutes. It is spring weather so there isn't a lot of sunlight, but there is a shade included. I recommend this set. Fun times for years to come.
