    Ways to Make Your Office Chair Taller

    There are several ways to increase the height of your chair. All you need are some DIY skills to do it at home, or you can also take help from a professional to make things work. 

    Due to budget restraints, getting a new chair or table is not always feasible. Still, after reading this article, I am sure you will be able to figure out a cost-effective and foolproof way to make your chairs taller.

    Without further ado, let’s dig in

    Replace the Casters

    One of the simplest ways to increase the height of your office chair is to replace the casters. Typically, office chairs have casters with 2″ – 2.5″ diameter.

    Replacing them with a bigger diameter, like 3″ -4″, will give you an extra height of 1-2 inches. Furthermore, casters with more diameter provide a smooth movement on any surface.

    Here is an insightful video to help you replace the casters yourself.

    Replace Casters With Wooden Blocks

    Office chairs with casters have a standard height of 16″ -24″. As mentioned earlier, you can replace the casters with bigger ones to get an additional 2″ -3″ size. However, replacing your casters with wooden blocks is the way to go if you want even more height.

    You can cut small, square wooden pieces of the desired size or get them done by an artisan. Additionally, the wooden blocks allow you to get as much height as you want. But be careful; your chair can get wobbly and end up hurting you due to higher blocks.

    It is a cost-effective and efficient way to make your chairs taller, but you have to compromise on the maneuverability of the chair. The wooden blocks will make it a stagnant heavy chair that cannot let you quickly move around in your workspace.

    Add a Seat Cushion

    If you are not good with DIYs, getting some chair cushions is the most basic solution for chair raisers. They provide extra cushion for sitting on uncomfortable chairs for a longer time. Moreover, they also provide extra height.

    Typically chair cushions provide 2″ -2.5″ of height, depending on your weight. You can also opt for a firm cushion with more height to get a few more inches.

    Replace the Chairs Gas Cylinder

    Office chairs use gas cylinders, also known as pneumatic gas cylinders, attached at the bottom of the chair. This cylinder is responsible for regulating the chair’s height with the help of air pressure.

    Usually, gas cylinders have 5 “-6” in height. You can find separate gas cylinders with much bigger sizes and replace them to get a few more inches. However, sometimes replacing gas cylinders does affect the working on the chair.

    Ask a professional to do the job for you if you do not want to do it yourself. Due to its reliability, it is one of the most effective ways to get more height without compromising the chair’s design and functionality.

    To make things easier for you, here is a video explaining how to replace the gas cylinder of your office chair.

    Stuff Paper into the Cylinder

    Office chairs have gas cylinders that help you raise the height of your seat by using a lever on the side. The cylinder moves the chair up by releasing the compressed air. On the contrary, it lowers the base by compressing the air inside the tube. 

    One way to keep your seat height at the maximum is by adding paper towels inside the cylinder. In this way, your chair won’t fill in compressed air resulting in a higher seat. Although it is a cost-effective way to make your chair taller, it is inefficient. Stuffing your chair with paper will only provide a maximum of 1″ -1.5″ height.

    Place Shims for Chair

    Shims are wedge-like materials, and they are placed under furniture to protect the floor from scratches. Furthermore, they help in balancing your furniture.

    Shims are chair raisers that also aid in making your chairs taller but provide a slight height change. Moreover, they are placed under the furniture without a fixture. A little movement of the chair can displace the shims causing discomfort.

    Ideally, office chairs have a height of 16″ -24″. The drafting toolkit can provide a whooping 5″ -8″ additional size making it a suitable option for standing desks.
