Hi sleepy64,
You can see my thoughts about airbeds in general in this article. While any mattress can be a good match for a specific person because each person’s needs and preferences or the criteria that are most important to them can be very different … in general terms I would tend to avoid them unless there is a very compelling reason that an airbed would be a better choice in “real life” (outside of the many “marketing stories” that you will hear about them) than the many other options or types of mattresses that are available to you. For those that are committed to an airbed and are convinced that there are no other types of mattresses that will meet their criteria then there are some other airbed options that are listed in post #3 here that may be much better quality/value choices than Sleep Number/Select Comfort.
