Memory Foam Benefits



The Basics



Viscoelastic foam’s unique physical characteristics have led to its popularity in the bedding and medical industries. Due to its conforming aspect, viscoelastic material makes for a comfortable yet supportive mattress or mattress pad, and its low resilience works well in bed pillows.

Everyone can benefit from the foam’s capacity to redis- tribute weight and surface pressure caused by aggravated pressure between the skin and bony areas of the body such as beneath heels, hips, elbows and the back of the head.

If pressure is not relieved through body movement or technology, such as a viscoelastic foam surface, blood vessels may compress, inhibiting circulation and possibly irritating the skin tissue.

Performance Testing Pressure Reduction and Pressure Relief

Because viscoelastic foam can closely conform to the shape of the human body, it can efficiently distribute pressure over the whole surface. Pressure-mapping equipment is often used to calculate the degree of weight distribution.

During the mapping procedure, computer programs monitor pressure. The body’s impression is graphed to show which areas endure the most pressure (namely the shoulder blades, posterior region, head, heels, calves, and elbows).

Some viscoelastic foam producers perform these tests as an indication of how well the foam might act to minimize pressure. In the healthcare area, to be labeled as providing “pressure relief,” readings must be at 32mmHg or lower, whereas “pressure reduction” performance is agreed to occur between 32mmHg and 50mmHg.

When readings made on viscoelastic products are compared to those of conventional foam and other common cushioning surfaces, the pressure differences are notable.
