We LOVE our Casper mattress. It’s soft, comfortable, and most importantly keeps up cool throughout the night. We actually didn’t take it out of the box for about a month after we received it because we were moving soon, and we were worried it would be warped. It’s not! We had the original purple mattress before that is super hot, and actually about 5” shorter than what it should be. Our Nova is absolutely perfect, and I’ll never buy another mattress brand again.
