I wish I had one of these when I was young. This Seated Backyard Zipline Kit is designed to allow kids to travel through the air while remaining close to the ground. It does not put too much stress on their body and is not unsafe. The system has a bungee braking system that slows or stops the zipline. Riders can move up to 90 feet. The rope length and seat height are adjustable. This looks lots of fun to try, don’t you think?
