Very happy with mattress.  It is very supportive and comfortable.  I tried the newer mattress types both Purple and Tempurpedic and found I really prefer traditional mattresses.  I have lower back problems and found the other mattresses I tried were comfortable for naps but really took a toll on my body overnight.  They just were not supportive enough -  especially on the edges.  The Beautyrest Black Series 3 Firm mattress has proven to provide the support and comfort that the other mattresses I’ve tried could not provide. It truly is a great balance between firm support and cushioned comfort.  I am beyond happy with my purchase.
