The frame is made out of UV resistant galvanized metal, so you shouldn't see any fading in the sun, rust, or other problems with the climbing dome. The dome is able to accommodate children aged 3 – 12, so all the kids can play together in the yard. It can take a weight capacity of 1000 lbs, so it'll take a lot of children clambering all over it. Even though it's so sturdy, you can still easily move it around. Whether you're mowing the lawn or just rearranging your yard, it won't be a problem.
