This was a fantastic purchase. I was looking for a bounce house for my daughters birthday party and i got so much more! This is perfect to use indoors during the cold winters and the measurements worked perfectly for our basement..She loves it and burns off so much excess energy. We had about five 23 year olds bouncing at the same time (no accidents). You should put a play mat at the side opening incase anyone falls out of the entrance just for safety. It is durable, well made and well worth the money. I researched about 25 other bounce houses before purchasing this one and I could not be happier.
