I am saving for this 'must have' mattress. I have suffered from chronic back pain for over 15 years due to a low back injury, which required surgery. Mornings are so painful to get going, but recently I visited my sister in another town and her spare bed was this mattress, and for the first time in years I woke up without a backache, didn't even have to use my cane to get around the first hour of each day. I was absolutely sold and looking forward to my, hopefully soon, purchase. I can't stop dreaming about finally being able to get out of bed pain free. Amazing!
