Absolutely Amazing! I hated the current mattress I had but figured I'd swing for a mattress topper rather than buying a whole new mattress. THIS CHANGED HOW I SLEEP in a good way! I have lower back problems just from being at a desk all day and bartending all night. When I first laid this topper out I was nervous it was going to be too hard. However, I made up my whole bed, added the sheets and my duvet on top and I sunk into this topper! It supports my arch back, while my heavier areas sink in to the mattress. I slept like a baby that night. I am beyond happy with this purchase! Highly recommend​.
