Question: Does the pump use batteries or 110?
Document: Its very easy to fill and deflate. One friend slept on it who was a little heavy and he said during the night it deflated a little but he didn't bother to add more air. My grandson who is 2 1/2 sleeps very soundly on it. I think its a great product for the price.
Granted we have only used this twice at our cabin for extra guests but so far it has been great! No leaking and it sits well above the ground with the mid-rise style.
Currently employed overseas and this air bed allows me to sleep better, and wake up without a backache. I recommend this air bed.
Answer: no
