Reasons of designing holes in the middle of Plastic Stools :
1. Have you seen the square shaped holes in the stools ? Surely, your answer will be NO. It is so because holes are always designed round in shape. To prevent the breakage when you sit and to give it a proper structure, companies make the holes round.
2. Mostly, we place all the stools together available in our home. So, if there were no holes, then chairs will stuck easily when you will arrange them together. It is so because, due to the vacuum formed between the gap of two stools, air pressure is cause, which will help in twisting of stools.
3. Also, holes help in the griping of chairs. It aids you in easy moving and stacking of stools. It acts like a grip or finger hole for you.
4. In addition to this, holes can handle a weak extension or we can say force. The plastic used to get extended in all the directions, when a heavy weight person sits on it as the plastic is tough. So, to accommodate a high volume or weight, holes are helpful.
5. the other fact is that holes help to save the materials. Some of the material gets saved when companies make the holes in chair. As the number of chairs are manufactured, so in this way a huge amount of material is saved. Thus less money is used to make the stools and the number of chairs can be manufactured at the same time.
