I’m not sure I moved once my eyes closed the first night I slept on this mattress. I woke up rested and with no body aches. My old mattress was well past its expiration date. I’m glad I finally decided to purchase this mattress. I didn’t wake up hot one time. And I felt as though I was sleeping on a cloud. And, I never heard my significant other shifting in the middle of the night! It’s a win!
