Pretty expensive for what you get but seems like a decent bed. I think the foundation is overpriced so I would highly recommend getting a different foundation. .
It's a nice mattress, but not for me. It ended up being too firm and didn't help at all with my chronic sciatica pain. For reference: I'm 5'4", 150 pounds, and very athletic. I slept on a straight memory foam Tempur-Pedic for ten years before this and started shopping for a new one because of back pain. I gave Casper a month and never could get comfortable on it. I tossed and turned and dealt with a lot of numbness in my arms, stiffness in my upper back, and worsening pain in my lower lumbar region. Ended up initiating the return process. Jury is still out on the return process--I've heard mixed reviews about how this might go. Fingers crossed.
I love my new bed. It was a little firmer than I expected but I slept great on it the first night and every night since. I've had it for a while now and it's not showing any sign if getting an indent where I sleep. I generally sleep in the same position in the same spot every night. If you are someone who edge support is important to, this might not be the best bed for you.
