Visco-elastic foam, also known as memory foam, is currently enjoying popularity. This synthetic material quickly conforms to the sleeper's shape so that hips and shoulders sink in, but support is maintained under the spine, keeping it correctly aligned. Dispersing the body weight away from the pressure points is its particular benefit. One of the side effects of visco-elastic foam is that it holds body heat, making the bed very warm. Sleepers usually find they need a lower tog duvet or less bedding, but body temperature can be regulated by choosing a mattress from a company such as Breasley, that has a cover which employs Coolmax technology.
The most familiar of these are spring interior mattresses. Springs in heavier gauge wire give a firmer mattress; lighter gauge will give a softer mattress. The quality of the mattress is often determined by the number of its springs. Open coil and continuous spring versions are the least expensive and a budget mattress, unless made of foam, will be open coil.
Interior spring mattresses, whether open coil, pocket or continuous, are assembled similarly to a sandwich with the supporting springs between layers of cushioning on each side. The cushioning provides a barrier between the springs and the occupant. Fillings can range from inexpensive polyester to combinations of cotton, wool, horsehair, silk, mohair and cashmere, as well as better quality foams, including latex or visco-elastic foam.
