I have had the opportunity to try the Sleep Number mattress. I was excited to do so after hearing many good reviews and advertisements for it, but it did not meet my expectations. It did not provide a bad night of sleep, but neither did it wow me. My husband and I both selected a different number and tried out many different settings. It was just as comfortable as my former mattress. I don't think it is worth the additional cost. There are other less expensive mattresses that provide an equal amount of comfort as the Sleep number bed. My sister loves her sleep number mattress, however, so maybe I need to give it more of a try. This is not a bad mattress, just not worth the high price in my opinion. I would not recommend it unless you have already tried one and love it.
