Q. Is PU foam durable?

PU foam is not generally renowned for its durability especially when used as a mattress. High-density PU foam is used in mattress layers for support and friction reduction however because of its quality and density it has a limited lifespan. It may be torn apart or lose posture with time. A low-density PU foam mattress that is old may lead to long-term posture problems and other health problems.
