Try Reflex Foam! Reflex foam is made up of tiny bubbles which squash sideways when pressure is applied. This causes the foam to part-fit your body whilst trying to regain its original shape. Unlike memory foam, reflex foam does not mold around the user. It has a quick bounce back quality and is fairly firm offering improved sleep for people with certain health concerns, such as back and neck pain. This is so sleepers will easily maintain a neutral spinal alignment throughout the night. Density/Firmness Rating – What's Best For You?
