Foam Beds

Memory Foam

NASA had designed a material called "Memory Foam" (also called slow recovery foam or Viscoelastic) in the 1970s for the astronauts. It became the fastest increasing section of the mattress industry for the manufacture of Foam Beds.

Properties and Sizes

The Memory Foam adapts to the body weight and temperature on its own. It is receptive to the heat released by the body during sleeps. The foam assuages the pain and aches accumulated during the day and removes the irritating pressure points. Support is given to the spine, along with no measurable pressure on joints and bones. It can be bought in various densities like 3 pounds to 5 pounds (it means that 1 cubic feet of the foam weights 3 to 5 pounds) and thickness from 2 to 3 inches. Denser foam is more expensive and shows a better performance. Some beds are created from 3 inch or 4 inch of high quality, five-pound memory foam placed on a three-pound foam base (this has a density of 3 pounds per cubic feet). It has medium firmness and is not a soft bed.

When compared with conventional spring mattress it's contouring provides an enhanced blood circulation. The Rail system has been introduced which offers a firm seating border and a feel of stabilization. Some beds contain Latex, which has the disadvantage of being dynamic and bouncy. But it is more durable than memory foam. The memory foam beds are available in various sizes like Twin, Long Twin, Full, Long Full, Queen, California King and Eastern King. They come in Split firmness i.e. half the bed of one firmness and half of the other and are Split Adjustable i.e. both halves can move separate of each other. Polyurethane is added to foam mattresses to maintain its original firmness.

Advantages

When we sleep on a memory foam bed, each arc of the body is supported, abolishing tossing and turning. There is a feeling of weightlessness due to the optimum balance of softness and rigidity. The partner's movement does not disturb the sleep. They provide an excellent remedy for those who are frequently robbed of sleep. It is very useful for ill persons as it is responsive to temperature changes.
