This mattress is wonderful and I immediately noticed a difference in the way I feel in the mornings. I used to wake up stiff and sore and felt unrested but with this I finally feel like I actually slept during the night, I feel refreshed and ready to start my day instead of wanting to just go back to sleep. I have not woke up with my neck hurting even 1 time since switching to this new mattress. It is not a thin mattress that will lose its comfort-ability in a few short months, this is well put together and will last. The mattress is firm without being to firm to get comfortable on like some firm mattresses are. I just can not say enough how much I love this mattress.
