My mother have gotten me this for a recent Christmas gift and I have to say that I absolutely love it, ever since I have gotten this bed I have not been tossing or turning, I have had more hours of sleep, I have felt fresh everytime that I have gotten up, and I can just set it to the number that makes me feel the most comfortable (my number is 14). This bed was real easy to set up no problem. The spring mattress beds that I had slept in before has made me feel sluggish and not to mention it was really uncomfortable. I am so glad that my mother have gotten me this bed, now I don't have to sleep on a spring mattress no more. The Sleep Number Bed has 25 years warranty. This bed featuring great performance and ultimate sleeping comfort with, High Profile Ultra Plush Euro-Pillow Top, Super Soft Contouring Comfort Layer, Refreshable, Removable, Refluffable Smart Top, Hypo-Allergenic Belgian Medicott Terry Stretch Knit Cover, Body Balance Multi-Zoned Support, and Impression Resistant Pillow Top.
