I bought this for my twin grandchildren who just turned 2. It’s perfect!! They are the perfect age and they can take turns easily. With the pandemic that we are in the midst of, they can’t go to the playground. This slide can be used both in doors and outside. I give it 5 stars. Also, thank you for the speedy delivery. It came 2 days earlier than expected and therefore, arrived just in time for the twins birthday!
