Why does a chair have 4 legs?

No matter how the seat is made, the chair with the fewest legs needed to allow easy movement in two different directions is the one with four legs.

Sitting is hard. It’s hard on our bodies, which are long and flexible and meant to move, stretch, and be used, not to be bent over in weird positions for long periods of time every day. Also, it is hard to understand because we don’t usually think about it. We slouch into a desk chair, sure that everything will be fine because sitting is just sitting and a simple act like that can’t lead to anything bad.

Without going into too much detail about how a simple chair is put together or how it stays together, it has four legs because if it didn’t, we would fall over. Every day, we take this for granted, even though we depend on it every time we sit down and trust that it won’t let us down. We keep sitting in chairs even though we don’t know how they work or why they have four legs.

Today is all about the number three. This series from the University of Houston’s College of Engineering looks at the people who came up with the ideas that keep our society running.

When I was young, my family and I would visit my grandmother in a small town. I would sometimes help get eggs from the chicken coop in the morning, but I was too young to help milk the cow. A few times, I did see my older brother milk the cow. I think he milked the cow while sitting on a stool with only one leg.

I found Neolithic figures in Romania that were made around 4700 BC. These are both pictures from museums. According to the book, they found many different types of seating furniture, such as stools with three or four legs. Given how old four-legged chairs are, it’s harder to figure out why. We don’t have the same reasons as the first people. We only have proof that they knew about these kinds of furniture. Because a flat piece of wood can be held up by four legs, one on each corner, and this was the most stable way to do it, my personal guess, and I want to stress that this is just a guess, was that four legs were the best choice.

A three-legged stool is an engineering wonder. It is more stable than a stool with four legs because the ends of all three legs are always in the same geometric plane.

Why doesn’t a stool with three legs move?

A stool with three legs will never move because only three points (the legs) must be in a plane. The chair won’t move because the three points are always in the same plane.

Why don’t most office chairs have three, four, six, or seven legs instead of five?

So, moving from one side to the other takes almost no energy at all. When you have five legs, your center of gravity is always moving away from where you need to be to stay stable. So, a chair with five legs is more stable on an uneven floor. The “diagonal of support” moves toward the center as more legs are added.

Why does a table with three legs never move, but a table with four legs sometimes does?

Because the floor was not even, the stool legs could be different lengths. If all four legs are the same length, the stool will shake because one leg won’t be touching the ground. The stool won’t be held up by the other leg, but by the three legs that reach the floor.
