Select Comfort Sleep Number Bed 4000 Review

I have been plagued with back pain for years and decided to try the 'sleep number bed'.  I know I like a firm mattress so I started with  number 85.  I woke up the next morning with almost no lower back pain.  Nothing is going to be 100%,  except maybe a miracle, but this bed was absolutely one of the best investments I've ever made.  Also,  it's nice to be able to adjust your number according to sleep position- I like it a little less firm for sleeping on my side or extra firm when sitting up to watch tv.
