This is the first mattress I purchased on my own. My last one was almost 10 years old and was causing me back pain, because it had zero back support. The Casper was simply delightful to unbox. I was afraid when i first saw it, because I had no idea how they could pack a mattress into a small box. It’s been 30 days with my new mattress. I am sleeping well, and it’s very comfortable. I now have a different type of back pain, but I think it’s because my back is actually supported instead of hanging on for dear life. Overall, I would reccommend this mattress.
