This has been one of my best Amazon buys to date! I was in desperate need of a new mattress. I read tons of reviews and settled on this one. I had never purchased a bed in a box before. It was really cool how it puffed up after unpacking. We slept on it that night. It’s a very comfortable mattress. I have chronic lower back pain and this mattress has helped me exponentially. I’m so happy I purchased this mattress.
