This mattress is amazing!!! I was very hesitant to buy a mattress online, but it actually turned out to be a great buy.  It is a bit firm, but you sink into the perfect spot with your body heat.  I woke up with no back pain, and no sciatic pain!! I was super excited, couldn't wait to go back to bed the next day.  I would definitely recommend this mattress and I would definitely buy it again!
