I don’t really know how the assembly went—we hired a local company to do it for us. They did use the BILT app, so you may find that useful if you plan to DIY. The final product is phenomenal. My four-year-old loves it. Some of the reviews show this product with a balustrade and picnic table on the bottom but those aren’t included. That is a feature on the “Skyfort with a Tube Slide” and not a feature of the “Skyfort III.” The reviews for the two products are combined and it makes it confusing. Otherwise, I recommend this play set 100%.
