We have an air bed and like it pretty well. Ours came with a 20 year warranty which is better that almost anything else. One recomendation I can make is to get one that has the sleep number feature so you can gage what works and what doesn't. Its hard to gage otherwise and the firmness of the bed will change over time and with changes in temperature. NOt a big deal but its really helpful to have a numerical indicator of where the air pressure is.
Then next issue is what kind of topper is on the air bed. This can range from almost nothing to pretty fluffy pillow tops and different densities and thicknesses of memory foam.
