I purchased this so that I can sleep in my office when required to shelter-in-place for hurricanes or other weather events. Gave it a good test to make sure this is the one. It inflates quickly and effortlessly, and maintains excellent air pressure for at least a week. Also deflates quickly and is easy to put back into the bag that is included. The mattress is super comfy and light, which means I can easily lift it out of the way and work around it. (Or I could have just deflated it daily but I really wanted to test it.) After hearing me gush about it for a week, my college-aged daughter has convinced me to let her have this one tonight and buy myself another. I'm not sure why there are a couple of 1-star ratings on here, they don't make any sense. This mattress is excellent in quality, a million times better than the one I had in the past.
