I bought the King Koil Luxury Queen Size Air Bed from Amazon. I moved across the country via airplane and had to wait 2+ weeks for my belongings to arrive with the movers.
It's a 20" high air bed. The air can be adjusted to be the most comfortable; there is a firmer edge around it; the pillow area is a bit raised; it's durable; and it has a built-in pump. Idk if it comes any smaller than Queen, & Queen sheets fit perfectly.
I was nervous that I'd find the air bed to be difficult to sleep on, but it was a wonderful 5-star lifesaver!
