I wanted an exercise space for my cats to safely enjoy the outdoors and this is perfect. It was easily put together, seems very secure and could work on a patio too. This is on the grass where the kitties will enjoy it in the shade but when it is time to mow, two people can pick it up and move it to a new location to mow beneath it. It is 7'2 inches long and 3'4" tall at the peak. It has a sail shade over a small portion of it. It is working out exactly as I had hoped it would. Five Stars!
