I haven't slept more than 6 hours in a row for the last 7 years and I woke up in pain routinely, since I started using this mattress I have slept longer, I move around less, and I experience less pain. I have degenerative disc disease and have actually woken myself with stabbing pain just from making a wrong or abrupt move in my sleep. This mattress is so conforming and comfortable that this seldom happens any more. If you need a mattress this is one you should strongly consider buying.
