It’s been said that sofas usually last from 7 to 15 years. However, the length of a sofa is also dependent on the type of material used for its cushions. Some types of foam are more durable and long-lived than others. It all depends on the foam’s density.
When we refer to a foam’s density, we’re not talking about how firm the foam is. Instead, density refers to the quantity or mass of foam per a measurable size or volume. Most types of foam have a density of 1-3 lbs., and the higher a foam’s density is, the longer it will last. This also means that denser foams tend to cost more. But if you know your specific needs for your couch are, you can budget accordingly.
If you are only planning to use cushions occasionally, you can use poly foam for your cushions, since it only lasts 1 or 2 years. If want something that’s comfortable, but will last a little longer, super soft foam might be right for your couch. If you want your cushions to last as long as possible, then you should invest in high quality foam such as high quality HD36 or high quality lux foam, which is made to last around 16 years.
