I had the BEST night sleep with my new extra firm queen mattress.   I love, love it.  I had to switch to a better quality mattress and extra firm becuase my old soft mattress was causing my back to hurt.  No more tossing in my sleep.  My new mattress is very comfortable.   It does not feel hard, it is soft and I have comfortable movement in the bed.  I wasn't sure how I would like extra firm but I am extremely pleased with my new mattress.  I also think the quality of the brand is superior!
