A few days ago, I briefly introduced the choice of stair chairs, including university classrooms. Ladder chairs are the most common in any university. According to our common form, we can know its material: the backboard is made of curved wood fire board, covered with high quality hemp fiber. Mobile tablet can save more space. The hardware is made of high-quality steel with electrostatic powder sprayed on the surface. The seat plate adopts damping recovery mechanism, no sound and slow rebound.

　　Due to the difficulty of the venue, the vast majority of tier chairs have to accommodate a large number of seats. If the venue facilities are relatively small, it would be better to choose a stepped row of chairs. The effective allocation of sites can appropriately increase the total number of seats and complement each other. Secondly, because of the choice of stepped row chairs, people sitting in the back can easily see the content of the performance stage and are not easily tired.

So, how should you choose a step chair?

Impression is very important

　　Although some people say that one cannot look at things by appearance, how can one continue to understand if one cannot attract others? Exquisite atmosphere, pleasing to the eye, not only makes consumers want to buy, but also improves user comfort. Therefore, when you choose, you can choose according to your preferences, which one is more attractive to you, you can first understand ~

When you choose, you must personally experience the comfort of the row chair and consider whether its backrest design is ergonomic

　　Why? Because the backrest designer is very special, it can effectively reduce noise, and can adjust the height freely, with high flexibility. In addition, the quality of the row chair needs to be considered. This part can start with raw materials and consider quality based on material properties. As mentioned in the first part of this article, generally speaking, the stepped seats will use a damping recovery mechanism, there is no sound and the rebound is slow.

Understand the spring quality of the row chair

　　At present, the latest durable spring reversal method is gravity rebound. Its core is gravity rotation, which has excellent quality and long service life.

The following three points must be noted when choosing a ladder chair:

　　1 Look at the material, high-quality solid wood multilayer board and flame-retardant fire-retardant board, man-made board double-sided board use first-class board, the selected boards should be joined together, seamless, no holes, high-quality polyester paint near the cover, neat and smooth , The line is clear, it is a better plate.

　　2 When choosing the main keel stainless steel plate, we will see if the manufacturer adopts national standard products. Whether to carry out electrostatic treatment, degreasing, anti-rust treatment, sand blasting, polishing and other solutions for metal products is a guarantee, otherwise it will endanger the service life of the row of chairs.

　　3 Check whether all the screws on the row chair assembly are anti-return, anti-loosening, difficult to dismantle by hand, and whether the connecting parts are safe, firm, impact-resistant and vibration-resistant.
