Bought this for an Airbnb. We were a little skeptical when the mattress didn’t fully inflate as soon as we opened the package (it was only like 5” tall and did not appear to be growing still) but we let it sit overnight and when we came back the next day it had doubled in size. And it’s suuuuuper comfortable! My wife and I both have jointback pain and this mattress is just as comfortable as ours that cost an embarrassing amount more. Highly recommend
