Beds with a firm comfort rating are great for certain sleepers. Firm mattresses give way a lot less under body weight, creating a firm and solid platform that allows perfect spinal alignment. People who like to sleep on their backs and stomachs will greatly benefit from sleeping on a firm mattress.
