My first night’s sleep on the Nova Hybrid mattress provided me such comfort compared to my old very expensive mattress that I almost could not sleep I was so excited.  I have had severe shoulder pain (I sleep on my side) for years and last night, my first night on my new Casper Mattress, I did not experience any shoulder pain.  I can’t wait for my second night!  I told my husband it was so comfortable I was not going to get out of bed all day.
