ISO stands for the International Organization for Standardization, which develops and publishes international standards to ensure quality, safety, and efficiency in products and services, including mattresses.
A firmness test measures the support level of a mattress, typically using a standardized weight and pressure distribution to evaluate how well the mattress maintains its shape and provides support for different body types.
ISO standards for testing are established guidelines that define the procedures and criteria for evaluating products, ensuring consistent and reliable results across different manufacturers and testing environments.
