Like any other product, foam comes in a wide range of quality and firmness.
The two most important factors of foam are DENSITY & ILD (firmness.)
Density is nothing more than how much the piece of foam weighs relative to it’s size. Foam Density is determined by taking a cubic foot of foam (12" x 12" x 12") and weighing it. If the foam cube weighs 2.9 lbs, the density is 2.9. If it weighs 1.2 lbs, the density is 1.2. The higher the density, the longer the foam should last. The best foam for extended use is called HR, or High Resilient foam. HR foam has a density of 2.8 or higher. Rest Assured, when having work dona at La Habra Foam & Fabrics, we ONLY use HR foam!
(Indention Load Deflection) refers to the firmness of a piece of foam.
The lab puts a 4" x 15" x 15" piece of foam on a flat surface. Then a round metal plate, 8" in diameter, pushes down on that piece of foam. The amount of pounds of pressure it takes to squeeze that 4" piece of foam to 3 inches (25% compression) is referred to as the ILD. A low ILD, (such as 10), offers very little resistance and is a soft piece of foam. At the other end, a piece of foam that takes 43 pounds of pressure is an extra firm piece of foam. Generally speaking, ILD’s of 15-24 are considered soft, 25-32 are medium, 33-40 are firm, and 41+ are considered extra firm. The comfort range for most people is 25-35. Foam does soften slightly with regular use.
In addition to typical Polyurethane foam, we also offer LATEX, VISCO ELASTIC and DRYFAST Foams.
Sometimes referred to as “Pincore”, represents the best foam available for a mattress or cushions. Latex is inherently anti-microbial, anti-bacterial, dust mite free, and has thousands of tiny air channels. Because of this natural ventilation, it provides more breathability, keeping you warmer in the winter and cooler in the summer. The density of Latex is 5.0 (+/-.5) and generally lasts 30 years.
Visco Elastic Foam, also known as “Slow Recover” or “ Memory Foam” is the foam of the future. Originally developed for space programs over two decades ago, it has really caught on with the general public for mattress toppers and other applications. As a person sits or lies down, this foam conforms to the body and anything else that applies pressure or weight. Visco Elastic foam has a Density of 5.0lb and an ILD of 14. Memory Foam creates a sleeping experience like no other.
Dryfast foam is suited for outdoor use where moisture, precipitation, and other weather elements are present. This includes patio furniture, layered under Phifertex© material, or in marine cushioning such as personal watercraft. The large, open cells provide a degree of airflow not present in other foams, allowing it to dry quickly even after complete saturation. The Dryfast foam formula is anti-microbial and helps suppress microorganism growth, common in damp areas.
