After lots of research, i wanted a memory foam bed to help my osteoarthritis in my lower back and the neck injury i have pain from. Sleeping on my side and back and being overweight helped me decide on this matress. All i can say is i wish i had done it sooner. The sharp shooting pains down my legs have gone away. Yes, i will always have back pain BUT this matress helps me so much. It sleeps a little warm for me BUT i'll take it to have less pain. I also liked the partial makeup of natural (non carcinogenic) materials. The salesman online was totally honest with me about the percentage of the natural fibers in the matress. You have to be honest when tellimg them your hieght and weight. The price was really good for what you get. The base had to be assembed but, i did it and i have no mechanical ability - take a breath and do the few simple steps and nothing was missing.
