Rome is credited with the next big innovation in resting comfort around 200 B.C.E. when cloth sacks were stuffed with softer materials like wool. Rome's wealthy citizens enjoyed mattresses made of sacks filled with down feathers. By this time, beds were raised off the ground onto platforms. Sleeping off the ground avoids pests and drafts; and the ruling Roman class wanted nothing to do with either. Raising the bed off the ground also serves to make it easier to get into and out of bed, and supporting the mattress in a frame helped it retain its shape.
The mattress is also designed to distribute the weight of the body evenly. The heavier parts of your body will sink into the mattress. It will reduce pressure points on areas where the mattress is pressing against the body. A high quality mattress must be able to relieve the pressure points on you shoulders, feet, and others areas of the body.
This is the part that provides comfort. Padding is usually made of polyurethane foam, puffed-up polyester, or cotton batting. Some mattresses have a foam layer just below the quilted top layer. Softer foams feel almost moist to the touch, and firmer foams do not spring back as quickly. Below this layer, there is a layer of cotton batting that caused the mattress to feel firmer in areas such as the middle of the mattress. Finally, there is an insulation layer that lies on top of the coil springs so that they cannot be felt from the top of the mattress. It also protects the coils from damaging the top layers.
