Hazardous substance testing
Hazardous substance testing
Ensure that all materials comply with international environmental standards, with zero formaldehyde and zero heavy metals.
Durability testing
Durability testing
Conduct tensile strength and compression permanent deformation tests on sponge samples.
Fire resistance test
Fire resistance test
Display the flame retardant performance test report of the fabric.
Spring system testing
Spring system testing
Ensure that each independent bagged spring is free from damage and abnormal noise.
Quilting accuracy
Quilting accuracy
Check if the pattern is aligned, without any jumpers or loose ends.
Symmetry and flatness
Symmetry and flatness
Ensure that the surface of the mattress is absolutely flat, without any unevenness.
Durability rolling test
Durability rolling test
By rolling tens of thousands of times (such as 50000 times), the overall structure is checked for stability, whether the internal materials collapse, and whether the height loss is within the standard.
Edge support test
Edge support test
Test the retention of support force of the mattress edge after long-term compression.
Final inspection
Final inspection
Conduct a final visual, tactile, and odor check on the finished product to ensure perfection.
