|Dec 5, 2022

There are a few ways to modify the desk chair height to make it fit your needs. The procedure may vary depending on the type of chair you are using. This post will examine seven original methods for raising your office chair without purchasing a new one. Even though some are free, others are comparatively cheaper. 

It will also suggest some height-adjustable chairs you can purchase to save time and effort.

How to Make Office Chairs Higher

1. Manually Replace Your Office Chair’s Gas Lift Cylinder

A gas lift cylinder, also referred to as a pneumatic cylinder, is the device that raises and lowers the height of the chair seat. 

An office chair with this type of technology typically measures five inches in length. However, some go as high as 10 inches.  

To raise your office chair, you can swap out your present cylinder for one that offers more length. 

A gas cylinder replacement is a very straightforward procedure. The steps are as follows: 

  • Turn the chair upside down or position it sideways on a table after lifting it to its highest point.
  • To separate the cylinder from the chair's base, hold onto the latter and strike the end of the cylinder where it extends from with a hammer or rubber mallet. This ought to set the cylinder and base apart.
  • Take the cylinder out of the chair's tilting mechanism and securely bind it to the metal part with a pipe wrench. Remove the cylinder and turn the screw counterclockwise. 

Ensure you insert the new cylinder into the chair's base and tilting mechanism before turning it back upright.

2. Add Casters or Glides

You can add office chair casters or glides to the chair's legs if you don't have a height-adjustable office chair. This will give you a few more inches by lifting the entire chair off the floor.  

Here’s how: 

  • Flip the chair over to access the bottom of the legs.
  • Screw the glides or casters onto the legs and flip the chair back upright.
  • Test the chair after fastening them to ensure it is stable and does not sway. 

3. Using a Pillow or Cushion

Another choice for the height of the chair seat is to use a pillow or cushion to increase your height when seated. You will gain additional padding as a result. 

Try out a few different pillows or cushions in various sizes and shapes to find one that is comfortable.  

Ensure the pillow or cushion is firmly secured to the chair to prevent slipping or sliding.

4. Use a Drafting Stool Kit

Purchasing a drafting or ergonomic stool kit is an additional technique to raise your workplace chair. It enables you to use your existing chair with a standing desk. 

Office chairs have a standard seat height between 16 and 21 inches. A drafting chair has a maximum height of 30 inches. This means you can add up to nine inches of lift or more using the height-extension kit. 

There is no denying that drafting stool kits gives you a significant raise, which is advantageous. However, remember that the majority of these kits only function with particular brands of office chairs. 

5. Use a Footrest

If the legs of your office chair aren't movable, you can use a footrest as an office chair height extender.  

Office chairs with footrests allow you to put your feet up while sitting. You can sit higher in your chair and find a more comfortable posture when you raise your feet. 

Choose a footrest that suits your needs from among the available options. A larger footrest can be more suited if you have a lot of space for your legs under your desk.  

In a limited space, a smaller model is the better choice. Some footrests may include extra amenities like storage spaces and massagers. 

When using a footrest, put it next to your chair for ready access. A footrest with non-slip pads is excellent if you don't want to worry about keeping it still.  

Additionally, check that the footrest's height allows your knees to form a 90-degree angle when sitting.  

The variety of footrest options makes it highly probable to find one that suits your needs.

6. Stuff Some Paper Towels Down the Gas Cylinder

Although it may sound strange, placing paper towels within the gas cylinder column will assist raise your standard seat height. Take these actions: 

  • Remove the cylinder's spring part from the column.
  • Put paper towels in the column. When you put the chair back together, ensure you make them compact to prevent the gas spring from settling.
  • Finally, reposition the spring to see the height increase. 

7. Use Wooden Block Platform

You can use wooden blocks instead of casters if you don't want to spend money to increase the height of your chair. This can be anything you carved out to elevate the standard seat height. 

First, get rid of the default casters if your chair has some. You can now fasten the legs to the blocks to create a secure base.  

Tape the blocks to the base's legs or, better yet, drill bolt-sized holes and use those to keep the chair in place.

Benefits of an Adjustable Height Chair

Many people spend the majority of their workday sitting at a desk of some form. This makes it easy for them to forget to stop and pay attention to their posture.

Prolonged postures affect the shape of our body and functioning ability. They also have an impact on our productivity.

These factors make it crucial that the office furniture and chairs we select provide our bodies with the best possible support. Our setup should enable proper ergonomics within our working environment. 

Here are a few reasons why we should have the appropriate height when working:

Relieves Back Pain

Sitting for long hours can be very stressful on your spine. However, if you convert to adjustable desks, you can choose between sitting and standing. Back discomfort might be relieved by standing for just one hour after sitting.

Upgrade your workplace chair to one with ergonomic characteristics if you don't like the concept of a standing desk for proper support and greater comfort.

Benefits of an Adjustable Height Chair

Reduces Stress Levels

Employees will inevitably experience stress at work on occasion. In some situations, stress can be a motivator that helps with deadlines and quotas. However, in others, it can impede productivity and lead to emotional exhaustion.

Adjustable desks and height adjustable chairs can help workers manage stress by encouraging improved posture and comfort.

Reduces Risks of Poor Health Conditions

According to medical professionals, sitting down is now compared to smoking. The risk of various chronic health issues, including type-2 diabetes, obesity, high cholesterol, heart disease, and even some malignancies, is increased by spending all day at a computer. This is because your cardiovascular system worsens when you are seated.

Humans are to move around and be physically active. However, switching to adjustable desks and height adjustable office chairs for your business can help by motivating staff to change positions more frequently. This benefits by increasing calorie burn and blood flow, which lowers the chance of long-term health problems.

Enhances Concentration

It's crucial to keep your mind engaged, especially as you get older.

Adjustable workstations and chairs encourage employees to walk around more, but they also increase blood flow, which boosts focus.

Standing up aids in improving brain function by circulating blood through your body and head.

While changing positions may take some getting used to for employees, there's a good chance that doing so will increase their productivity at work. It will also make them more awake and prepared.

Improves Energy & Mood

Energy levels and emotions seem to improve with certain factors (height of chair seat, chair adjustability, etc.) in the workspace.

In a seven-week research, standing desk users reported less stress and weariness than those who spent their workdays seated. 87% of people who use standing desks reported having more vitality and enthusiasm throughout the day.

However, once back at a desk, the general atmosphere returned to normal. This suggests that anxiety, depression, and other mental health issues are linked to a sedentary lifestyle.

Your employees will benefit from having height-adjustable chairs and desks because they enable them to spend their workdays standing, sitting, or doing both.

Improves Energy & Mood


Setting the optimal height for your chair is one of the many aspects that must be balanced to maintain proper posture when working at a desk. Use the methods above to accomplish this without throwing out your sustainable office chairs.

Remember that the best ergonomic computer chair is the one that fulfills your specific needs.
