The supplier reports ISO 9001 certification, more than 10 production lines, 11–20 R&D engineers, 11–20 quality-control staff, and annual polyurethane foam output of 40,000,000 pieces. It states that production began more than 20 years ago and exporting began in 2013. The supplier offers OEM, private-label, and ODM services, and describes one-stop sourcing, technical support, and after-sales service. However, the available trade records show only one transaction associated with each of two buyer entries, so customer-case depth and commercial track record cannot be fully established. The records also show differing locations for the company and production facilities, which may reflect separate administrative and manufacturing sites.

It has a registered company address in Changsha and reported production bases in Linyi and Foshan, indicating a mixed manufacturing and trading structure with multiple locations.
