Mattress Spring Fatigue Tester，ASTM D3574 ，how to test mattress for sagging
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)
