90±5mm/min Furniture Durability Comprehensive Tester for the surface of mattress

Introduction of product:

This tester is designed according to the latest national standard. It is suitable for a set of durability testing for spring soft mattress,and relevant measurement of it.It uses a certain weight of roller to do rolling test on the center of mattress, simulating the effects to the

mattress after the body of people rolls on it. The tester does loading durability test for the

edge of mattress using specified loading cushion and force value.It can also simulate a people sits on the edge of the mattress,and the effect caused by the bottom loading on the mattress.After a certain number loading,compare the height of cushion surface and its surrounding edge before and after the test.Assess the quality of the mattress according to change of hardness and damage of mattress.

Test items: include the following tests and measurement projects:

1. durability test for the cushion surface.
2. durability test for the edge of cushion.
3. height measurement of the mattress.
4. Measurement of the Hardness value.
