We have a small backyard and an active 4-year old. This is a perfectly sized outdoor playset for her and friends when they come over. The materials feel sturdy and everything arrived in great condition. We hired somebody to put it together otherwise it probably would have taken us forever :) and once it was assembled we couldn't get her off of it. She's spent so much time on it. She's a tall 4-year old and the slide is a lot smaller than what she's used to at the park but this is still great and helps build her strength as she climbs up. The rock-climbing element is great too for strength and balance, and most importantly - fun! The chalkboard is a soft tarp-like material, and sand isn't included... but super easy to get a bag of sand to fill it up. Definitely a win for all of us. Feels safe, secure, and solid.
