Complaint
The durability of mattress edge is mainly used to test the durability of mattress edge to meet 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 strong spring mattress, ordinary spring mattress, foam mattress, brown fiber elastic mattress. After the durability of the edge, the height of the pad can be tested automatically to avoid the error of manual height measurement.
