Beautyrest Black® Hybrid CX-Class - Medium, Queen Mattress is like heaven on earth. I must admit, the black mattress was a questionable idea in my original thought process. However,  the black keeps the mattress looking beautiful.
  I found the queen size to fit perfectly on my frame. The look of this mattress is really incredible.  It is very elegant and the material is so breathable and durable. The mattress is also incredibly comfortable.  It is firm without being hard and incredibly soft without being uncomfortably soft. 
   This mattress is incredible but it is also expensive.  You are receiving a high quality product and I believe you get what you pay for. This mattress is a pretty penny but most definitely worth every dime. I would recommend this to anyone seeking a comfortable, breathable,  elegant mattress and has the funds to afford this one.
