Three, the purchase of student desks and chairs should pay attention to six points.
Students' desks and chairs are more professional, young and active, and they are in a period of long physical knowledge. Parents attach great importance to them, so school facilities and equipment managers should be very careful when choosing desks and chairs! Because unreasonable school facilities and equipment will have a very important impact on the healthy growth of children.
1, to buy a student desk and chair, you must first look at the manufacturer's certificate about this product. As most friends know, many manufacturers or distributors in the market are uncompromising when buying student desks and chairs. Of course the price is unbalanced. At this time, in order to find the excellent quality of manufacturers, we need to see that they have two certificates: one is environmental protection certification (ISO 1400 1-2004) and the other is national compulsory safety certification (3C certification). The manufacturer has two certificates, one desk and one chair, and the quality of the general materials provided will not be any problem. You can pay attention to it when you buy it.
2. Don't just look at the pictures and prices of students' desks and chairs. First, it's really convenient. Second, there are many manufacturers. If you order online, you can compare many desk and chair products and choose the best one. This is a good side, but everything has two sides. This child, buying a student desk and chair, only looked at the pictures and prices on the Internet and rushed to book it. There are indeed many hidden dangers, because some manufacturers will replace the original raw materials or the same things with recycled materials or inferior materials. The addition of raw materials is small. This can't be seen in the picture, and the price is relatively low, so it is easy to be fooled. So I suggest you go to the manufacturer to see the samples as much as possible, and then start construction after confirmation. If it's too far away, you can also combine the last suggestion to watch the products through video, or look at some information of the company online to see the online word of mouth.
3. Pay attention to the safety of students' desks and chairs in use, especially when buying preschool students' desks and chairs. It is best that all edges and corners are smooth. Students' desks and chairs are all smooth edges and corners, which will not cause great harm to children even if they stumble at ordinary times. Another point is that children have an active feature, so our student desks and chairs need to be very strong, so we should choose steel student desks and chairs, so that children can't be damaged, which can effectively prolong the service life of student desks and chairs.
4. Pay attention to health when choosing materials. Students' desks and chairs, like children's furniture, are rich in materials, such as wood, wood-based panels and plastics. These materials have their own characteristics, but they should be selected on the premise of firmness and practicality. Specifically, it requires environmental protection and no odor. The coating on the surface should not fade, and it is not easy to scratch, and it is important to choose tables and chairs with plastic veneer or other harmless coatings, because children often come into contact with them.
5. Students of different grades should choose according to their height at different ages. Ergonomic desks and chairs are the size and height of children's age and body, which is conducive to their healthy growth. For specific standards, please refer to the description of the classification and standard of desks and chairs written in the last article. Of course, even students in the same grade sometimes have great differences in height due to different levels of physical development. What should I do? If the school has prepared enough funds, you can consider buying optional tables and chairs with adjustable lifting height! This can be adjusted according to each student's own height, which may be the best solution.
6. The shapes of tables and chairs should not be too fancy. Schools with desks and chairs for students are generally not too fancy. On the one hand, it is an outdated requirement, and it is also easy to distract children from learning. It is better to choose a simple shape and powerful function.
After reading the above introduction, I believe everyone knows the price and standard size of student desks and chairs. Generally, plastic ones will be cheaper than plastic ones, and the whole set of tables and chairs will be more expensive than a single one.
