Truly impressed. I gave it two days to take shape and it’s been difficult to get out of bed since. It’s the perfect balance of firm and plush for me, a back sleeper who tosses and turns. For years I had lower back pain from lumpy foam mattresses and shoulder pain from the coils of much firmer ones. Now, I feel like I climb into a cloud and melt right to sleep. And I STAY asleep which is amazing. I wake up refreshed and my days are so much better thanks to this mattress.
