We just got this slide to use as indoor entertainment for our special needs son. He is 38.5" tall and it's perfect for him. We set it up in our kitchen dining area so he doesn't stop when his feet reach the end like on carpet. He loves it! He uses it off and on all day! He enjoys going down on his bottom and also head first. ;) Great indoor physical activity! Would highly recommend this slide. It easily folds flat for storage in a closet or garage.
