This is the greatest slide I have ever seen. I take my three Grandchildren to the different parks around the area andI have yet to see any slide better. The quality is supurb! I have never seen a side winder and in our situation, we were adding it to a tree camp and they slide right out in front of the tree camp and right back up the steps to go down the slide again and again. They love it! It is safe, sturdy, and so well made. The customer service I received from Wayfair was excellent. I have put them in my address book and will defiantly use them in the future for so many things that they offer.
