The Intex Ultra Plush 20" Bed Height Queen Air Mattress with 120V Internal Pump is the most comfortable air mattress I've slept on. After sleeping on it we left it in our family room for the kids to use for sleep overs and I found them playing on it most days. It held air and didn't need refilled at all during this time. I really like the height of it because it makes getting on and off easier. My favorite feature was the handy included internal pump. This way there is no way to lose or forget the pump, even the ac plug stores inside the mattress. This is a great air mattress!
