I received  this  Beautyrest - Silver BRS900 - C  Extra Firm Mattress,  from  Tryit  Sampling.  I  received  it  as  a  free  sample,  and  I  love  it.  I   have been  sleeping  on it for more than a week, I love it. I  feel  so good  in the  morning,  after  a  good night  sleep  on  this amazing  Beautyrest  - Silver Mattress.
