Q: I purchase this air mattress in late October and two month later I was laying on the mattress I move my arm and a fist size hole appear over my head. The mattress arrive fast and was easy to set up. If you plan on using this mattress for a guest bed or for your kids when they come home for the Holiday or summer break please get something else. Not worth the money. I had Coleman and small hole appear and the patch does not work but for this mattress the patch does work for a small hole not the fist size hole.
