Proper adjustment of the chair is essential for doing work. Otherwise, you will be sitting awkwardly while doing your work.

Raising the Chair

It is the easiest way to adjust your chair, and you have to look for a handle control feature below the seat. This seat handle will help in adjusting the seat height. In some chairs, there is a knob feature that is used in which you have to rotate the knob for moving it up and down. In case of a lever, if you don’t know which one to move, read a manual instruction.

Raising the Chair

Once you have pushed the lever, the chair will start moving gently; make sure to raise and lower the lever repeatedly as it will help in the proper functioning of the seat, and do this until you come to the spot you are actually comfortable with. Once you are done with the height, move the lever back to the original position. You can also adjust the chair’s height by standing in front of it and raising it to the knee cap level. Now sit on the seat and check if you are comfortable with the height. Most probably, you would be.

Height Extension Kits

Height extension kits are an easy solution for increasing the height as well. These kits are commonly available online and are also available in hardware stores. From adding the height, you have to add the extension in your office chair. These are available in various designs, and you can choose with which you are more comfortable. I would recommend an extension that has feet resting on it and will give you support and help rest your legs on it.

For installing this kit onto your office chair, you will require some basic tools like a screwdriver, rubber mallet, and wrench. A set of instructions is given with every height extension, and you have to follow the same steps for the right installation.

Height Extension Kits

The main set includes the removal of the wheelbase from the lower side of the chair, and you can do it by removing some pins present on the base of the chair and gently hitting it with a rubber mallet, making sure not to hit too tight or it will cause the damage. Once the wheelbase is removed from the lower side of the piston under the chair, insert the extension and place the wheelbase back as it was before. Carefully close all bolts, and that’s it! It’s all done.

Replacing the Wheels

Another one of the easiest ways to make your office chair higher is by replacing the older wheels with new ones. Wheels are usually available in hardware stores and also available online as well. Putting on wheels that are higher than the normal wheels will increase your chair’s height and help in the easy rolling movement of the chair.

Replacing the Wheels

Casters with bigger wheels than the standard ones will move smoothly in the office and remove dirt getting entered or stuck on them due to their continuous movements. Replacing the wheels from the chair is an effortless task to do. You have to secure the chair and remove the metal pin holding the wheel. Please insert the new wheel and fix it tight by putting the metal pin back in it. Make sure all the wheels are done well so that they don’t come off easily.

Replace Chair’s Gas Lift Cylinder

To get the best height for your office chair, you should check if it has a gas lift cylinder with more than 5 inches of travel/stroke. If this is not enough to give you the right height, consider getting one that goes as high as 8 inches.

Placing Wooden Pieces

You can raise the chair’s height by placing wooden pieces between the seat and its lower body. All you need to do is drill a hole 2×2 in the wooden pieces so that screws can pass through it. Wooden pieces are prepared as per the requirement of the chair. Raise the seat and place those pieces in between the seat and lower part of the chair.

Threaded Posts for Old Chairs

If your office has old-style chairs without rolling wheels at the bottom, you can make the height adjustments in such chairs with the help of threaded posts. For this, you have to clean the chair initially and remove the dirt. Cleaning the chair is also an important step for this chair. Make sure you oil it well by putting it upside down after lubrication, taking any rag, and cleaning the excess oil off the chair as it will avoid slippage.

Secure the chair by putting one of your feet on it so that it cannot move right or left when you are working on it. After this, handle the chair well, move it clockwise and in an anticlockwise direction, and look for the raise. Usually, the chair will raise in an anticlockwise direction. Repeat the process until your desired height is achieved in which you will be able to work comfortably.

You can now easily continue raising the chair by spinning it; after the desired height is attained, turn over the chair and sit on it. Look, it is either comfortable and on your desired sweet spot where you want to work or not. If yes, then it is good to go, and if not, you can give it a few additional spins as well. The chair will rise for ¼ inch with each spin.

Adjusting the chair will provide you a better experience while working at your office, and you will feel relief from posture issues.

Add A Platform Below Your Chair 

If you don’t want to mess with the mechanics of your office chair, simply add a platform below it. This can be either wood or another flat item that is solid and stable enough not to slide around on carpeting or floorboards. You’ll also need to lock your wheels so it doesn’t roll off this makeshift seat extension!
