I started going to the chiropractor for lower back pain and sciatica that was killing me. I knew my mattress was in bad shape. I had the box spring for way over 10 years and the top mattress for about 7. I decided to buy a new mattress set. It has made all the difference in the world. I bought a firm set to support, not only my spine, but my weight also. I am overweight. The reason I am relating this information is that possibly if you are suffering from lower back pain, it might be because of your mattress not supporting you properly. I have cancelled my chiropractic appointments because my back doesn't hurt anymore. In the long run, the mattress will pay for itself because I won't be paying the chiropractor every week for adjustments.
