How Long Do Mattress Protectors Last?

Service life depends on membrane integrity, laundering, heat exposure, elastic wear, spills and how often the protector is used.

Replace based on function

Do not rely only on calendar age. Replace a waterproof protector if the barrier is peeling, cracked, delaminated or no longer reliably blocks liquid.

Care can shorten or extend life

Repeated high heat can be hard on waterproof laminates. Following the product-specific wash and dry instructions is more useful than a universal lifespan estimate.
