Foam Failure — The #1 Reason to Replace
Foam failure is the primary reason Indian homeowners replace sofas. When the central seat area becomes concave — you can see the depression when the sofa is unoccupied — the foam has permanently lost its cell structure. This happens faster in sofas with density below 32 kg/m³ and accelerates in humid climates. The test: press down firmly on the seat cushion and release. A good foam returns to original height within 2–3 seconds. A failed foam stays compressed or rises slowly over 5–10 seconds.
