If you have back pain then you need to get a memory foam mattress, it is that simple. The reason why you need a memory foam mattress is that it will mould itself to your unique body shape and it will adjust to fit your sleeping position. This means that your back will be in the best posture all night long no matter what position you are sleeping in, and it means that your muscles are able to rest and relax throughout the night rather than stressing and straining to keep you in a comfortable position.
Memory foam is heat reactive, meaning that it will compress more the greater the heat. As your torso is hotter than your limbs, the mattress will sink more where your torso is. This means that the mattress will shape itself perfectly to your body shape and your sleeping position, holding you with just the right degree of comfort and just the right amount of support. Because you are perfectly supported by your memory foam mattress, no matter your body shape, size or your sleeping position, your back will have as little stress and strain placed on it while you sleep.
No matter the source of your back pain, the solution is a memory foam mattress.
