Love this castle. I have a climber who needed a safe alternative to sofa scaling and chair acrobatics at one year of age. This helped re-direct to a safer alternative. We added rubber exercise mats under our castle, which we have placed in our home on wood floor. It has been used daily since purchase. It has been used as a castle, boat, dog house, play ground, etc. obviously great for little imaginations.Getting the slide to lock in was a bit of a challenge initially, however set up was less then 20 minutes.
