1. Look at the elasticity: Lie down by yourself and turn it around a few times. A good spring will not move or be uneven, and it can immediately restore its original shape.
Second, look at the stability: use both hands to shake the product back and forth, left and right, and shake it firmly, indicating that the frame is good.
3. Pay attention to the quality of the wrapping cloth: buy leather, you can pinch one place with two fingertips and pull up and pull, it feels strong, and the restorability is good quality.
Fourth, look at the process: If it is a folding bed with a steel frame structure, pay attention to the welding place to be smooth and free of voids, the coating should look uniform and soft, and the surface of the steel pipe treated with [plastic spraying process] is high in hardness and more resistant Grinding, more shiny. However, if the [baking paint] process is used, the surface of the steel pipe is more prone to scratches, which leads to easy oxidation and rust, and there is no luster.
