Frequently Asked Questions

ASTM D3453 is used to measure the compressive performance and load-bearing characteristics of flexible cellular polyurethane foam materials commonly used in furniture cushions, automotive seating, and other comfort-related applications.

The test helps manufacturers determine how foam materials behave under compression, ensuring proper support, comfort, and durability in products such as furniture cushions and automotive seats.

Compression testing ensures that seat foam provides proper support, comfort, and durability for passengers while maintaining performance under repeated loading during normal use.

The test measures compressive force–deflection characteristics, which indicate how much force is required to compress foam to a specific thickness or deformation level.

Foam samples are cut into specific dimensions as required by the standard and conditioned under controlled environmental conditions before the compression test is performed.
