Mattress Spring Fatigue Tester

The King Size Foam Fatigue Tester is a single-station pneumatic fatigue testing system designed for evaluating the long-term durability, compression resistance, and structural stability of full-size foam mattresses. The tester accommodates standard King and California King mattress sizes and applies controlled cyclic loading to simulate repetitive human use over an extended service life. The system supports both constant force and constant displacement loading modes and is suitable for laboratory-based durability evaluation and standard compliance testing.

Application

The King Size Foam Fatigue Tester is used for fatigue and durability evaluation of the following products:

Full foam mattresses (polyurethane foam, memory foam)

Latex mattresses

Hybrid mattresses (foam combined with spring or latex layers)

Mattress core foam blocks and assembled mattress systems

Large-size cushioning foam products

Mattress prototypes during product development

Production quality control and type testing of mattresses

Standards

The King Size Foam Fatigue Tester complies with or references the following standards:

ASTM D3574 – Dynamic Fatigue Test by Constant Force Pounding

ISO 2439 – Determination of indentation hardness and deflection

GB/T 26706 – General Technical Requirements for Mattresses (related clauses reference)
