Verdict
If you are going to spend more money on a household item, the mattress is a great place to spend it. The Select Comfort Sleep Number 9000 is the most expensive mattress I have ever used, but rewards that expense with the most sleeping comfort I have had. The best part of the mattress is that you can adjust as your bed as your needs change. I started off skeptical of the Sleep Number bed and now I see what all the fuss was about, this is the best mattress I have ever owned and thanks to the adjustable firmness it will continue to be the most comfortable bed I have owned no matter how my needs in a mattress change.
