The AirDream air mattress is very comfortable and is even good for everyday use, unlike most sofa bed mattresses. Overstock's price is great and gets better if you can combine it with a coupon and free shipping, although the shipping cost is always really cheap anyway. I believe the dimensions of the full mattress should be 52 x 72, not 54 x 72 and the queen is 60 x 72 (at one time this ad said 60 x 80 and I couldn't convince overstock it was wrong, but at some point it got corrected). Check out airdream.net for size info and cost comparison. Another thing, this ad says there is a 5-year limited manufacturer's warranty, but Legett and Platt that makes the mattress has a 3-year limited warranty normally, so just beware but don't let that stop you from buying it. AirDream.net says, "The mattress, air chamber and air chamber valve are covered for a three year period and the inflator for a one year period starting from the date originally purchased." Finally, when putting the bed away, make sure the mattress is centered over the sofa bed frame and not slightly hanging over the thick parts of the frame at the sides. The reason is that the air bladder can get pinched by the thick parts of the frame and could lead to leaks, primarily on the sides of the air bladder. They don't mention this in any documentation, but a Legett and Platt employee told me that when I was talking about leaks I was getting on the one I replaced with my purchase here. It does come with a repair kit if it springs a leak, but avoiding leaks of course is your best option. Enjoy your sleep!
