Due to the cold Chicago weather I bought this for my grandchildren who will soon be 4 and 1 years old. They love it! Compact and very easy to set up. grandma loves it! The child climbed over the sides, the sides collapsed to allow her to get in and out, and then with a little help they snapped into place. However, do not leave your children unattended. Strong, durable and at a great price! What's not to love! If I need a gift like this, I'll buy it again. We also bought balls for the pit. They don't smudge. Easy to remove although I didn't fully insert the pit piece into the round zip cover. No problem, it just sticks out from above. Great toy and quality!
