It may be easy to overlook a five-star review, but I'm a picky sleeper. Consider me a Goldilocks of mattresses. The setup only took about fifteen minutes to pull it out of the plastic and lay it on the boxspring. You have to wait about 72 hours for it and your body to adjust. It is THICK! I love how high it is. The pillowtop is softer than what I've been used to but it doesn't compromise the body support. I no longer wake up with any soreness, my pillows are no longer deflated when I wake up, and I could comfortably sleep without a pillow on this mattress. It isn't bouncy, there's a moderate amount of shock-absorbency to consider. I'd be hard pressed to believe any poor reviews of this mattress. Side and back sleepers will be very comfortable on this.
