Product description
American standard mattress roller tester is a machine designed to simulate the continuous rolling of human sleep, which meets the requirements of various mattress manufacturers and standards. It is used to judge the quality and service life of the mattress and strictly comply with the requirements of the national standard for mechanical testing. Suitable for soft mattress, strong spring mattress, ordinary spring mattress, foam mattress, brown fiber elastic mattress, etc.
