Worst purchase in a very long time. We've had SO many problems with this set. I wish I would've heeded some reviewers warnings and spent more money on a different swing-set.  
The manufacturer (Backyard Discovery -not Wayfair) is AWFUL!   One response from them when we notified them that MULTIPLE parts were missing was, "Oh, yeah, that happens all the time.  We don't actually check the pieces before they're mailed, we fill the boxes based on weight."  Short version of our experience: this product was ordered in July and now, in September, we still don't have everything we need to finish putting it together.  
Wayfair has been great throughout the process however and we will order from them again.
