I never wake up with pain anymore. As a side-sleeper, I appreciate how supportive this mattress is of my spine. What's best though, is that it has enough give and support so that my hips and shoulders don't hurt either. I've slept on similar versions of this kind of mattress and even in the spots where it's not worn down, the Tempur-Pedic matttess is significantly better. My only concern right now is whether it will feel too warm in the summer. Regardless, I love sleeping on it.
