I purchased this for my kids birthday party(5 years old). I was impressed with the material. It felt like puncture resistant cloth/ material. The interior has a jumping and climbing area which is more prompt to be ruptured ( from previous experience), however this bouncing house is laced with soft latex rubber that adds an extra layer of protection .
It does comes with some patches for easy fix but Im glad to say I dont need it!
My only critique is that the blower does make a decent amount of noise if you put it inside your house like me. However if you set it up outside your house preferable grass area , it will be fine.
I would not set it on concrete for the purpose of rupture.
Overall my kids were very happy with this toy and their friend always wanted to come over for the weekend now. It is definitely a party starter!
