We are no strangers to plastic stools, but do you know why the small hole in the middle of the plastic stool is used? It turned out that there was a good use for inserting a pole in the middle of the plastic stool. Now that it's not too late, take out the plastic stool at home and try it out.
1. The small hole in the middle of the plastic stool is actually for the convenience of transportation. If there is no hole in the middle, the stools will be difficult to separate if they are stacked together. If there are small holes in the middle, they can be separated well even if they are put in more. .
2. You can insert a stick in the middle of the stool, and then pass through the child's clothes. This can correct the child's sitting position and prevent humpback, which is very convenient.
3. Plastic is tough. If the body is very fat, sitting on the plastic stool will stretch in all directions. If there is this small hole, there will be a weak extension, which can effectively prevent the stool from cracking.
