Environmental protection is also an aspect that cannot be ignored in the design of modern staff chairs. As global attention to sustainability increases, more and more designers are turning to recyclable or biodegradable materials to create chairs. This not only reduces the impact on the environment, but also conveys a green office concept. In short, the staff chair is a complex product that integrates science, artistry and humanistic care. It should not only meet the basic sitting and lying functions, but also take into account the user's health, comfort and work efficiency. Behind every staff chair is the designer's in-depth study of ergonomics, precise grasp of material properties, and detailed insight into user needs. In today's globalized world, a good staff chair can not only cross national boundaries, but also cross cultural and language barriers, becoming a common choice for professionals around the world.

The most important point to be considered lines in the elastic webbing manufacturing. The lines may look like aesthetic wiewed from the outside. However, the lines on the elastic webbing indicate the strength and elasticity of the elastic webbing. Our company, which makes extremely suitable products according to world standards, attaches great importance to the use of quality products by its customers. If you would like to buy an elastic webbing, we would like to emphasize the following: - If there are two lines in the products, one tire with a thick number is used. It is stated that it is 100% stretch. - If there are three lines in the products, two tires are used. It is stated that it is 60% stretch. - If there are four lines in the products, three tires are used. It is stated that it is 50% stretch. There is an important point to remember here. You can add as many lines on the elastic webbing. However, an elastic webbing conforming to world standards is as much line as mentioned above. Our company produces and offers the best quality products to customers at this point.

Mother button clamp Size: 280 * 220 * 777mm Button tensile testing machine Button strength machine: The purpose of this test is to define the responsibility of garment manufacturers to ensure that buttons, buttons, and fasteners are properly secured to the garment, preventing buttons from detaching from the garment and posing a risk of swallowing by infants. Therefore, all buttons, buttons, and fasteners on ready-made clothing must be tested by a button strength tester. This function performs uniform and vertical tensile testing on various buttons on clothing to check whether their firmness meets relevant safety standards Standard: 16CFR1500.51-53, ASTM PS79-96 Operating instructions: 1. Install the fixture, cooperate with the test button, and lock the test sample onto the base tightly 2. Put down the fixture, grip the buttons tightly and pull them upwards. Each group of buttons should be able to withstand a minimum of 17 pounds of tension (7.72kg) and maintain it for 10 seconds without any signs of looseness or damage. At least 20 buttons per model need to be tested simultaneously to be considered qualified If one of the buttons is loose or damaged, or if it is replaced, it is necessary to retest all of them
