I bought this Triangle, along with the climbing wall, for my youngest granddaughter's first birthday, at my daughter's request. She LOVES it! As soon as I set it up she was on it, climbing up and skipping every other rung as she went. But her 4 1/2 year old sister loves it, too. She climbs up and over the top and down the other side. She wanted to "slide" so I told her to flip the wall over, which she did, climbing up and sliding down the steepest angle she could get, and then she lowered it and decided to use the slide as a surfboard! "Pretend that's my wave, Lolly!" she said (the Triangle). Kids are so smart and creative, and they will have fun with most anything you give them. But this climber was a great investment. It will get years of use.
