Have you ever wondered why plastic stools and chairs have holes in them? The reason will make you say "wow."

Chairs are an integral part of our everyday lives. Whether at home, in the office, at school, at a shop, or at an event, a plastic chair is the easiest seating option. Being lightweight, affordable, durable, and easily portable, it's considered one of the most popular pieces of furniture in the world.

However, have you ever noticed that most plastic chairs have holes on their backs? People often overlook this, thinking it's simply a design element. The truth is, these holes aren't just for show; there are many scientific and practical reasons behind them. Let's find out why these holes are placed, making a simple chair even more useful.

The Secret to Easily Disassembling Chairs
The biggest advantage of plastic chairs is that they can be stored stacked on top of each other. However, when chairs are stacked on top of each other, air gets trapped between them. This causes them to stick together, making them difficult to separate.

This is where this small hole proves helpful. It allows air to escape, allowing the chairs to separate easily from one another. Therefore, this hole is very useful at large events, such as weddings, parties, or meetings, where hundreds of chairs are used.

Simplifying Production
To make plastic chairs, molten plastic is poured into large molds. Once the plastic cools and takes shape, it must be removed from the mold. Without this hole, removing the chair from the mold can be difficult and even lead to breakage.

The hole makes it easier to remove the chair from the mold and keeps the production process faster and safer. This means that the hole is not only a part of the design, but also an essential factor in manufacturing.

Saving Weight and Cost
The more plastic used to make a typical plastic chair, the greater its weight and cost. A small hole in the back slightly reduces overall plastic consumption. This saving may seem minor, but when millions of chairs are manufactured simultaneously, this small difference significantly reduces production costs.

Furthermore, the chairs' lightweight makes them easy to carry and transport. This is why plastic chairs are used comfortably everywhere.

Seating Comfort and Air Flow
Sitting on a plastic chair for long periods of time often causes sweating in the back. This is due to a lack of airflow. The hole in the back of the chair maintains air flow, making the person sitting more comfortable.

This means that this hole is crucial not only for manufacturing and storage, but also for user comfort. This is why plastic chairs are relatively comfortable to sit on, even in hot and humid weather.

Easy Drainage Way
Suppose water spills on the chair or it is left outside during the rain. Without the holes, water would accumulate on the chair, making it uncomfortable to sit on. However, the holes allow water to drain easily, allowing the chair to dry quickly.

This small feature also makes the chair easier to maintain and more durable.
