What is an isotonic foam mattress?

isotonic foam mattress is made of special material that gently corresponds to body contours for more comfortable sleep. Isotonic foam can be used as part of a complete mattress or separate mat for regular mattresses. This special material contains polyurethane foam combined with other chemicals to increase its density and viscosity. The isotonic foam mattress is sensitive to pressure and slowly returns to its original shape when used. This mattress was originally used to alleviate pain and prevent pressure ulcers in patients with hospital.

Isotonic foam mattress is commonly referred to as a memory foam mattress. This mattress is designed to match individual body contours by offering lower pressure resistance. Isotonic foam is used not only for complete mattresses, but can also be purchased as a separate top padding for a conventional mattress with a coil. Material density can help to relieve pain in pressure points caused by conventionalIt is usually much harder and more expensive than traditional polyurethane foam. Isotonic foam often has a slightly sticky feeling when used without a fabric covering. The thickness of this material can have a significant impact on the user's comfort. Very thin layers of isotonic foam compressing too easily and provide a small or no effect of suspension. Extremely thick layers are usually too soft for a comfortable sleeping surface.

isotonic foam mattress is available in both high and low density versions that have different weight and heat responses. The isotonic foam density can usually be determined by how quickly the material returns to its normal shape after pressure and relaxation. Foam with high density reacts mainly to the hev and molds into the outline of the body slowly. The low density isotonic foam mattress is more sensitive to weight and quickly corresponds to body contours. Low density foam has tEndence to have a slightly shorter life than a high density material, but it is often more comfortable to sleep.

This material was originally developed for the American space program at the age of 60. For some hospital applications, it was used commercially at the age of 80. For example, patients who have been restricted to the hospital bed for a long time experienced less pain and beds as they lay on the isotonic foam mattress. At the beginning of the 90s, these mattresses began to sell to the general public as an alternative to the traditional bedding with the coil. Their use has been widespread in recent years because production costs have decreased.
