1. Product Function and Application

The King Size Foam Fatigue Tester is a single-station fatigue testing machine designed for evaluating the durability and performance of full-size foam mattresses, including standard King and California King sizes.

It performs fatigue testing in accordance with ASTM D3574 – “Dynamic Fatigue Test by Constant Force Pounding”, simulating long-term, repetitive loading to assess the foam’s resistance to compression and deformation over time.

The system is ideal for mattress manufacturers, foam suppliers, and testing laboratories seeking to ensure product quality, consistency, and compliance with international standards for comfort and durability.

Widely used in the furniture, bedding, foam production, and material testing industries to determine the fatigue resistance, durability, and structural performance of large foam or composite mattress systems under repeated loading.

2. Applicable Test Standards

This tester meets or exceeds the requirements of:

ASTM D3574 — Standard Test Methods for Flexible Cellular Materials (Foam)

Dynamic Fatigue Test by Constant Force Pounding

ISO 2439 — Determination of indentation hardness and deflection

Other related foam compression and fatigue test standards
