I so wanted to love this mattress. It almost pains me to only give it 3 stars. When I first stretched out on its memory foam softness I was sure wonderful things were ahead. Almost immediately I suffered knee pain with my legs and arms falling asleep. My previous mattress was memory foam so my body was used to that system, but after two weeks I had to sleep in my guest room to test my sleep and for several nights I had good relatively pain free sleep(I have chronic back pain which is why I tried the Casper). I returned to the Casper and experienced the same deep discomfort that was difficult through the night and left me aching and fatigued all day. I will have to return it and start over. I couldn’t bring myself to give it less than 3 stars and your experience may be different, but sadly, this mattress isn’t for me.
