This mattress has stood up to the test of several sleepvoers and is still kicking it. Kids are not easy on air mattresses either. They are more likely to use them for sledding than sleeping. This one seems up to the job.
We used this mattress every night over a 4 day weekend and it stayed firm. If it lost any air, it wasn't noticeable. The bed didn't flop around during the night either. You can sleep in peace and wont wake up on the floor.
