LOVE THIS! My 15 month old has been having so much fun on these. We arrange them differently, and he is enjoying it immensely. The large yellow and red box is still a little tall for him, so we have to spot him when he climbs up on it, but I'm sure he'll grow into being able to use it on his own very soon. He loves to "slide" down the ramps and makes the cutest "whoa" sound each time. Quality material, should last for many years to come.
