All of our foam is high quality, American made virgin polyurethane foam. Density and thickness vary according to its seating application. Sofas and loveseats are thicker and less dense while dining and other thinner cushions are more dense. Our foam may be used indoors and outdoors. When used outside, our specially constructed cushions dry quickly. For even faster drying of any cushion, stand it on it's side in the sun!
Foam density is not weight; it is actually a measure of volume. Density is a function of the chemistry used to produce the foam, of additives used to increase density and of any additives used to improve the combustion resistance properties of the foam. Flexible polyurethane foam is measured in pounds per cubic foot (pcf). It is available in a broad range of densities, ranging from as low as 0.8 pcf to as high as 6 pcf. Most foam applications utilize foam in the 0.9 to 2.5 pcf density range. Foam density is a function of the density of the virgin, or unfilled foam. This is also called polymer density. If the foam contains no additives or fillers, the polymer density is the same as the overall foam density. When additives or fillers are used in producing the foam, the foam density will be higher than the polymer density. Generally speaking, the higher the polymer density of the foam, the greater the cost of the foam. However, this foam will generally also have better physical properties including support and durability. Don't worry... you don't need to understand all of this. You can trust that Leaders has developed the perfect formula to balance all these factors into the most comfortable and durable cushion in the industry.
