I love how comfortable and sturdy it is. I had never had a built-in pump for an air mattress,  good thing to note is that you can still use a manual pump as well, if you don’t have a place to plug in the pump.  It's quick easy to inflate and set up (3 1/2 Minutes). The built-in pump is life changing when it comes to blow up items. It is also quick and easy to deflate (4 1/3 Minutes). I am very impressed with this mattress. I am a big girl and I can sleep on this with out having to feel like i'm gonna pop it. I also used it for guests this past weekend and my nieces were jumping all over it.  But It lasted and still works perfect.
