Personally I wouldn't think about using any air mattresses no matter how expensive or supposedly "good" they might be.
From the few times I have attempted to sleep on "Coleman" camping ones sleep was non existent. Temperature and even elevation about sea level will change the "firmness" of said mattress. You can start out with it full at night and wake up in the morning with your body touching the boards under the mattress.
My suggestion if your REALLY want a good nights sleep is to get a good quality FOAM mattress made with a top layer of memory foam. Price is probably less than than the premium name brand air mattresses and you will never suffer waking up with your body hugging the board under the mattress.
