A petite individual would want to make their chair taller to level themselves with their desk. You can simply do this by using the lever for the height range.
Depending on your chair, you might have just one lever or several. There is an image etched onto the lever’s handle to show its function.
Once you’ve identified the one for the seat height, make sure that you are not seated. Stand slightly and pull the lever up.
Stop pulling once you’ve reached the height you want your seat to be at. To make it go down, you need to take be seated while you pull the lever up.
If you find that the chair still isn’t tall enough, you should look into getting a very thick and sturdy seat cushion.
You can also look into changing your wheel casters. If you install ones that are taller, it will also boost your seat height.
Finally, if you’ve tried everything but nothing seems to work in your favor, try the height extension kit. This will take a bit of time, but this is the surest way for you to convert a proper chair for short people.
