Swing with Swivel Spinner and nest attachments

I have this swing that is built for people with special needs although anyone can use it. It has high weight capacity and is a small size. I originally purchased it for my backyard but realized it would not fit. It's all still in box. There are two different swings included along with this swivel spinner connector piece which converts your swings on a frame into a spinning swing! It features unrestricted spinning and swivel action. The weight capacity for the swing is 400lbs and the swivel spinner is 590lbs weight restriction.
