While you should always consult your physician or chiropractor when it comes to finding the right mattress for your back pain, often times memory foam mattresses provide the best type of support and relief.
Memory foam mattresses come in varying degrees of softness, providing different types of support for your upper and lower back in some cases. A firmer memory foam mattress may be more ideal for some but not others, so if you're experiencing serious pain a special type of mattress may be needed.
