If the foam in your sofa cushions is not up to the mark, it can start to disintegrate and lose its softness in a short time. The sagging cushions can make the entire furniture look old and tired, and also make it uncomfortable for sitting. Replacing the foam is the best quick fix solution.
To
be familiar with the basics, foam is measured in two standards:
density and compression. Density refers to the amount of material in
one cubic foot; the more the density, the more the cubic foot will
weigh. Compression refers to the amount of force required to compress
the cubic foot by 25 percent. These are the basics of a typical foam. It is available in
multitudes of grades which can indicate the expected number of years
of wear and different stages of firmness in a wide range of price
list. It is also used to make upholstery.
Foam
is also rated by the expected years of use. Some products are also rated as high
resilience, which means high-quality cushion foam with a density of 3
pounds per cubic foot. Latex foam, which is made from rubber, can
have a density of 3 to 15 pounds per cubic foot.
Cushions
having a foam core wrapped with poly-fill can provide the best
rebounding properties. The inner core of the foam determines the part
of softness and firmness of the couch. The foam cushions provide the
rebounding effect that is absent in fibre filled cushions.
If
your foam cushion material is older than 10 years, or is beginning to
get a round shape at the front edge, then probably your foam need to
be replaced. Foams of varying densities offer the upholsterer an
opportunity to select a specific type based on the usage and the
client's needs.
