Put this one in my living room and inflated it and unplugged it for 24 hours, it lost some air but not enough you'd notice in your sleep
Overall a great purchase for the price
The self adjuster is awesome
Setting it up takes about 30 seconds of active time (unroll, plug in, set firmness), then 3 - 5 minutes as the mattress inflates to your desired firmness setting
I am keeping it on hand for guests and suspect they will be very impressed
We would buy again or give as a gift
