Why is there a small hole in the middle of a plastic chair? In fact, the design of this small hole is very useful, but many of you may not know the purpose of this small hole. Let’s find out more about the functions of the round hole on the plastic chair!

First of all, why does the small hole on the plastic part of the chair have to be circular rather than triangular, square, or other shapes? The simple reason is for the convenience of making molds. Because the circle has no corners, it is easier to remove the mold from the middle.

The second point is that the round hole on the plastic chair is not arbitrarily open and the size also has to meet the requirements. If the hole is too large, it will affect the overall structure and the stability of the chair. If the hole is too small, it is easy to get stuck when inserting a finger, and it can even scratch the finger. Therefore, the size of the round hole also has a certain standard.

The uses, tips and tricks with holes on plastic chairs

Convenient for disassembly

When storing plastic chairs, we will stack them together and place them in a certain position, or when transporting, we will also stack a large number of chairs together, saving space and facilitating transportation. If there is no small hole between the chairs, there will be no air circulation between the upper and lower parts, which can easily form a closed space. Due to the effect of air pressure, it is difficult to remove the chair. Therefore, this small hole will play a big role in making it easier to disassemble the chair.

Airflow and ventilation

Normally, if we sit on a plastic chair for a long time, we will feel uncomfortable. Especially in the summer, hot weather, sitting for a long time can make us sweat. The design of small holes on plastic chairs has the effect of airflow and ventilation, making the users more comfortable.

Convenient for transportation and unloading

When we want to transport the plastic chairs far away, we usually stack a large number of chairs together and thread a rope through the small holes in the middle to string them together. Connecting and fixing them will make it much easier to move the chairs.

If there are not many plastic chairs or if the chairs are too heavy for one person to carry, we can use a stick to pass through the small hole in the middle and lift them. Carrying will be easier and less strenuous.

Adjusting the correct sitting posture

At home, we can also use a stick to adjust the sitting posture. Children often have incorrect sitting postures when studying, and sitting for a long time in the wrong posture can lead to many bad consequences such as spinal deformation, visual impairment, etc. Therefore, you can also use this method to adjust and correct the sitting posture of children if there are no specialized chairs at home.

In addition, because children are relatively small, if the sitting posture of a child cannot be corrected, we can also insert a stick into the child’s shirt, and after a long time, the sitting posture will naturally be adjusted better.

Note: When we use plastic chairs, if we find that the legs of the chair or the surface of the chair are cracked, we should replace the chair to avoid falling and injuries caused by the chair breaking during use.

Therefore, the size of the holes must adhere to certain standards to ensure optimal performance and user experience.

The holes in plastic chairs make transportation and unloading more convenient. By threading a rope through the holes, multiple chairs can be securely stacked and transported together, reducing the effort required to move them. Additionally, if the chairs are too heavy for one person to carry, a stick can be passed through the holes for easier and less strenuous carrying.

At home, a stick can be used in conjunction with the holes in the plastic chair to help adjust and correct sitting posture, especially for children. By guiding the stick through the holes, the user can maintain a proper posture while studying, preventing spinal deformation and visual impairment caused by prolonged incorrect posture.

It is important to regularly inspect plastic chairs for any cracks or damage, especially on the legs and surface. If cracks are found, the chair should be replaced to prevent accidents and injuries that may occur due to the chair breaking during use.
