Types of Mattresses
Traditional Coil Spring - These mattresses are made from hundreds of small springs that supply a firm support. Heavier people may find these too soft and may choose a spring mattress with fewer, larger springs to spread the extra weight.
Latex Foam - A latex foam mattress is relatively firm and will hold its shape for many years. A natural latex mattress is preferable as the synthetic latex uses hydrocarbons in production while natural latex uses only sap from a rubber tree.
Air Mattress - Air mattresses are comprised of numerous small compartments filled with air that promote a degree of firmness with support. Models with controls that allow couples to have different air pressures on each side of the bed are also available.
Memory Foam Mattresses - These mattresses have often been recommended for sufferers of arthritis as they retain their shape and support the body in the right position.
Pillow-Top Mattresses - These are used as covers on top of a hard or firm mattress to make it more comfortable.
Remember that a good firm bed frame is essential to support whatever type of mattress is chosen, and a monthly inspection is recommended to ensure that the framework is not sagging. A sagging frame can be fixed by laying a 1" board on top of it, then the mattress on top of the board.
