I researched playsets for months before we purchased this kit. My husband, father and father in law worked 7 hrs to complete the playground. (My hubby did spend 3 hrs the prior weekend cutting down and labeling all of the lumber.) It is VERY sturdy. I liked the idea that we could purchase our own lumber. We bought pre-treated lumber and plan to stain it a dark redwood. My husband and both fathers have alot of experience with constuction and wood work. They all three made the comment that the set was "over built." We would recommend this kit- great price and great value!
