After having purchased this bed only 2.5 years ago, a major component of the bed no longer works. They don’t tell you upon purchasing the bed that the 20 year warranty is prorated if anything goes wrong with it. The pump which is the major component no longer works on my bed and therefore I can’t adjust the mattress. I feel so sorry for my spouse who is chronically ill and cannot adjust the make it comfortable for him. Customer service told me it would cost me almost $ 100 to replace the part. No satisfaction from the local store and from the national office. I will never purchase another sleep number bed in this lifetime.
