I love the height of this air mattress!  The 20" height makes it so it doesn't feel like I am sleeping on the ground and it is an easy to "sit up" on without having to position my legs oddly to be comfortable.  It is super easy to both inflate & deflate and compresses nicely to carrying/storage size.  Plus, being a queen size, it works well if you have extra guests staying over and not enough beds.  My niece loves it because it's comfortable and maintains its full inflation throughout the night.
