Have you ever paused while working and thought, “what is pneumatic chair?” Well, it might actually be the one you’re sitting on at that very moment.
Modern office chairs have a mechanism that allows them to move up and down, and this mechanism is known as pneumatics or hydraulics. As you read on, you will learn all there is to know about these chairs, from the components to how it works.
The combination of different disciplines like physiology, psychology, anatomy, and engineering, otherwise known in general as ergonomics, concerns how people interact with their surroundings. Ergonomics also focuses on how people like you can change the environment to have an effective and safe working practice. You could also use this in a system, such as how different departments communicate and apply to physical objects.
Ergonomics provides efficiency and safety to the people who will benefit from it in a particular area, such as an office. Chairs made with the principles of ergonomics provide users the comfort that they need to feel even if they are working.
You may often hear pneumatics or hydraulics, but what do they mean? People use these terms when there is an application of fluid power to an object.
Pneumatics use compressible gas, like pure gas or air, to allow machinery movement. Hydraulics, on the other hand, uses oil or any other incompressible liquidized metal.
Pneumatics is commonly associated with moving light loads and is easy and safe to store, generally used in office chairs. These chairs have levers that allow the chair height adjustment, compressing, and decompressing the gas inside the cylinder.
Chairs of this kind, designed to specifically support the user’s body while sitting for long periods, have many features that help you feel comfortable. These details also help in improving your body posture while sitting and support your health while working.
These chairs adapt to a user’s needs and are always associated with productivity at the highest levels, provided by the customized support these chairs can give you. If your chair has an adjustable depth, height, and lumbar support, it is most probably an ergonomic chair.
Pneumatic chairs have a single-acting cylinder, which has an air-filled spring inside it. This air chamber connects to a piston that moves inside, activating when you push the lever up or down.
The air inside compresses further with this action, making a lifting motion that allows your chair seat to rise. If the piston moves further out the chamber, this action results in the expansion of air inside, allowing the chair to lower.
A few components make up a pneumatic chair, and these parts help the chair provide support for you and be able to move up and down. You will learn about these parts in the following area as you read on. Knowing these components will give you an idea of maintaining a proper working chair for your convenience.
Components of a pneumatic chair
The base of these chairs typically has a three to a five-star metal base. You use this base to insert the gas cylinder. Then you shroud this cylinder with a telescoping cover, which will create the column, and on top of that is the seat.
The underside of the seat has the levers that you use to operate the chair’s pneumatics. These levers push down the piston, which allows the column to lift your chair up and down. The telescoping shroud protects the cylinder when this action happens, preventing the air pressure inside from bursting.
Common problems and maintenance
Indeed, you would know by now that you can find these pneumatic chairs in offices or your home office, and you use them daily. Wear and tear of this furniture would also occur often. How would you take your chair problems and solve them with easy steps?
Generally, you must insert strong adhesives on each of the screws before you insert them. This action makes their threading more narrow, making them lock tightly to avoid loose screws or suddenly springing when you sit down.
Are you annoyed about how your seat keeps sliding down? To fix that, you must first pull it to the level you want your chair to stay in and mark that level on the cylinder.
From the base of the chair, measure the length up to the mark that you made. Cut unused sticks, preferably yardsticks, and insert those between the area of the chair frame that holds the wheels and keep them in place with duct tape.
Regularly check your chair wheels for any squeaky parts. If fixing the screws won’t help, it is best to buy a new set of wheels the exact size of your chair.
You now know what to answer when someone asks you, “what is a pneumatic chair?” From the general information, to how it works, to the chair’s components, and how you can fix it without paying too much. You can help others understand what this chair is and improve it without buying a new one quickly.
