What is High Density Foam?

High density foam is a type of polyurethane foam that is composed of a large amount of open cells or bubbles that are packed tightly together. The result of this higher concentration or density is that air is able to pass through the holes in the cells with greater ease, making it much easier to provide comfortable padding for cushions, mattresses, and other similar products. Foam density of this type also tends to hold its shape with greater efficiency, allowing it to return to normal dimensions when any object is lifted from the surface of the foam.

One of the best ways to understand how high density foam works is to consider a mattress that is manufactured using the product. The structural foam used in the mattress allows it to conform to the contours of the individual sleeping on the mattress. At the same time, the foam provides support that allows the spine to remain in a natural position, eliminating stress on the back and neck. As a result of this cushioning effect, the individual is able to enjoy a deeper and more recuperative sleep, and is more likely to awake feeling rested and refreshed.

Unlike some other products, high density foam has the ability to regain the original shape shortly after any weight is lifted from the product. For example, a mattress made with this foam provides ideal support for the sleeper, but quickly reverts to its original appearance after the individual arises. Such mattresses will hold their shape for many years, providing a longer period of active use than mattresses using other types of materials.

There are several other common uses of high density foam. Cushions and pillows are often made with this product. Upholstery foam that is high density allows sofas and chairs to provide comfortable sitting for many years before any sagging or indentations begin to appear underneath the upholstery. The product can also be used for wall padding in recording booths and other settings, helping to muffle noises with great efficiency.

In terms of cost, products made with high density foam tend to be competitive with products manufactured using other materials. Often, the foam products can equal or even exceed the life of products made with other materials. For this reason, using this product for padding or as the main material in a number of products is both practical and cost-effective for manufacturers, as well as being affordable and offering long-term service to consumers.
