We can only speculate that they are evolved forms of wooden chairs used in the past. The wooden stools of the past were basically simple wood models with three wooden legs. They were the most basic of models used to provide a person with a place to sit.
Often they were not part of a table setting so they would be pulled up to an extra table or a bar which is how they are believed to have gotten the nickname, "barstools".
While the original bar stools were very simple pieces of necessary furniture, it probably wasn't expected that they would evolve to the popularity that they have today. In the 50s and 60s especially, these tall chairs really took off and could be found in nearly every bar or restaurant around.
This is when they really began to change shape and be found in different sizes, colors, materials and styles. They would only continue to grow from there.
You can also find bar stools in a variety of sizes and heights. You will find out that the height is one of the most important aspects of the bar stool. This is why it's very important for you to measure the table, bar, or countertop properly so you can get the perfect stool.
Bar stools have changed and evolved a lot since their early days. They are now available to suit most any needs or style. This has come about over time as people adapted them to fit different types of needs and situations.
Many people can remember using barstools in our childhood days. You may have sat at the breakfast bar preparing for the day ahead. We may also have experienced bar stools in the local ice cream parlor or even in the barber shop. These fond memories show us how much the bar stool has evolved over time.
The history of the bar stool shows us that they can fit in most any room of the house and even in the business place. Bar stools are functional and fun and have become part of an American culture.
These stools in commercial settings will often be swivel or floor mounted but those used in personal settings are typically not mounted. This has also changed throughout history however and it is acceptable to have any type you want that goes with your theme and dcor.
In the past, bar stools were made of mostly wood but now metal and wood bar stools are very common. Aluminum is a good choice of material for bar stools that can last indoors or out. As the years go by, we expect that the history of bar stools will continue to grow and evolve.
