Bought this for my 7 month old son. He loves to crawl through it. I like how you can see through the top.Tunnel does not stay put (like how it looks in the picture). You can bend it however you like but as soon as the kiddo starts crawling in it the tunnel begins to straighten out. Also, it doesn't stay extended all the way. When a child is crawling inside it scrunches up in places and can get a bit under foot.I also bought the tent that it can attach to so I'm hoping that will help the tunnel stay in place better.
