Comfort: Comfort in foam selection refers to how the material feels when someone sits or lies on the couch. Many people prefer softer foam for a plush experience, while others may prefer firm foam for support. Studies show that high-density foam (above 2.0 lbs/ft³) often provides a comfortable balance between support and cushion.
-
Durability: Durability indicates how long the foam will retain its original shape and performance under regular use. High-quality foams can last from 5 to 10 years before significant wear occurs. For example, latex foam is known for its durability and resistance to sagging, whereas lower-quality polyfoam may have a shorter lifespan.

Higher density foam, which typically weighs more, provides greater support and durability. It does not compress as easily under weight. This characteristic results in a firmer feel.
Lower density foam is lighter and softer. While this can create a plush sensation, it may lose its shape more quickly. Softer foam often leads to discomfort over time, especially with frequent use.
Comfort level also depends on personal preference. Some people prefer a firmer seat while others enjoy soft, sinking sensations. Therefore, the right density caters to individual comfort preferences.
In summary, higher density foam offers better support and longevity, while lower density foam provides a softer feel but may require more frequent replacement.
