My kids ages 2 1/2 and 18 months LOVE this tunnel. We got it for the kids for Christmas and keep it put away and bring it out about 3X a week in the evenings when we have had a slow day and the kids didn't get any energy out. They go CRAZY, they play and run and scream and crack up! My husband drags them through the house super fast and they sit in it and laugh their butts off. You can play peek a boo, or roll balls through it, the possibilities are endless!
