If your office chair doesn’t sit at the right height, sinks in, or doesn’t provide the level of comfort you want, the gas bottle may be the problem. The gas cylinder, also known as the cylinder or piston, is responsible for the chair’s height adjustment and overall stability. In this guide, we will explain how to remove the top hat from an office chair and give you helpful tips on replacing it quickly and successfully.
Before you begin removing the cylinder from your office chair, gathering the necessary tools to ensure a smooth and successful disassembly is essential. Here are the tools you’ll need:
Adjustable Wrench. It is essential for loosening and tightening nuts and bolts. It allows you to adjust the wrench width to fit different nuts sizes and provides a secure grip.
Rubber Mallet or Hammer will come in handy when you need to tap or gently strike parts of the chair to loosen them.
Pipe Wrench or Large Pliers. These tools will help grip and turn the cylinder during removal. They provide a strong and secure grip, allowing you to apply the torque to unscrew the cylinder from the chair mechanism. Please make sure that the pipe wrench or pliers are large enough to securely grip the cylinder without slipping.
Clean Cloth. A clean cloth is essential for protecting the cylinder from scratches or other damage during removal. You can wrap the fabric around the cylinder using the pipe wrench or pliers, providing a protective barrier between the tool and the cylinder’s surface.
Lubricating Spray (Optional). Although not necessary, a lubricating spray can be helpful when removing the cylinder, especially if it’s been in place for a long time and has become stuck.
Remember to exercise caution when using the tools and follow the instructions carefully to avoid accidents or damage to the chair or yourself.
You must follow several steps to successfully replace the gas lift on an office chair. Let’s talk about them in more detail.
So, the first thing to do is to parse the database. You should act like this:
Turn the chair upside down to access the base.
Locate the locking clip or mechanism that holds the cylinder in place. It can be a horseshoe clip, a retaining ring, or a locking screw.
Use an adjustable wrench to remove the retaining clip or screw. Be careful not to lose small parts.
As a final step, after removing the locking mechanism, gently tap the base with a rubber mallet or mallet to disengage the cylinder from the base.
With the base separated from the chair, inspect the cylinder for any signs of damage or wear.
If the cylinder is in good condition, you may be able to reuse it. However, if it’s faulty or you want to upgrade to a different type, proceed with its removal.
Wrap a clean cloth around the cylinder to protect it from scratches.
A pipe wrench or large pliers grip the cylinder tightly, ensuring a secure hold.
Rotate the cylinder counterclockwise to unscrew it from the chair mechanism. Apply steady and firm pressure until the cylinder comes loose.
Done, you did it!
If you’re installing a new cylinder, check the compatibility with your chair model and ensure it has the correct dimensions and weight capacity.
Then apply a small amount of lubricating spray to the bottom of the new cylinder to facilitate smoother installation (optional).
After that, insert the new cylinder into the chair mechanism, aligning the threads.
Begin turning the cylinder clockwise by hand to secure it in place. Once it becomes difficult to rotate by hand, use the pipe wrench or large pliers for a snug fit.
It’s time to return the base of the chair to its original position:
Reattach the retaining clip or screw to secure the cylinder in place.
Make sure all parts are properly aligned and secured.
Check the seat height adjustment by sitting on it and using the lever or mechanism.
The chair should move smoothly and stay at the right height without dropping.
When selecting a new gas lift for your office chair, several important factors must be considered. Taking the time to choose the right gas lift will ensure optimal performance, stability, and comfort. Here’s a guide to help you make an informed decision:
Chair Model Compatibility. Before purchasing a new gas lift, ensuring compatibility with your specific chair model is crucial. Different chairs may have varying mechanisms and attachment methods for the gas lift. Check the manufacturer’s recommendations or consult the chair’s manual to determine your chair’s compatible gas lift options. It will help you avoid any installation issues or incompatibilities.
Height Range. Consider the desired height range for your chair. Gas lifts come in different lengths, each offering a specific range of height adjustments. Measure the distance between the seat and the floor at the lowest and highest desired positions. Choose a gas lift that accommodates this range while ensuring the chair is comfortable for your needs.
Weight Capacity. Gas lifts’ weight capacity ratings indicate the maximum load they can support. Choosing a gas lift that can handle your body weight and any additional weight, such as a laptop or documents you may have on your lap while seated is essential. Selecting a gas lift with a higher weight capacity than required is recommended for added durability and stability.
Quality and Durability. Opt for gas lifts made from high-quality materials to ensure long-lasting performance. Look for gas lifts constructed from sturdy steel or other durable materials. Reading customer reviews or seeking recommendations can help you gauge the durability and quality of different gas lift options.
Installation Method. Gas lifts typically attach to the chair’s mechanism through a threaded connection. Ensure the replacement gas lift has the same threading specifications as the original one. It will ensure a secure fit and prevent any wobbling or instability. If you’re uncertain about the threading size, consult the chair’s manual or the manufacturer for assistance.
Consider Additional Features. Some gas lifts offer additional features to enhance comfort and functionality. For example, you might find gas lifts with a tilt mechanism that adjusts recline angles or locks the chair in a specific position. These additional features can provide a more customized seating experience, so consider your preferences and needs when choosing a gas lift.
Budget Considerations. Gas lifts are available at various price points, so it’s important to establish a budget beforehand. While opting for the cheapest option is tempting, prioritize quality and durability over cost alone. Investing in a reliable and high-quality gas lift will ensure better long-term performance and avoid the need for frequent replacements.
By considering these factors when choosing a new gas lift, you can find the right one that fits your chair model, provides the desired height range and weight capacity, and meets your comfort and durability requirements. Researching and selecting the appropriate gas lift will contribute to a more comfortable and functional office chair experience.
In addition to replacing the gas lift, you can take a few more steps to improve the overall comfort of your office chair (read more about this here). By applying these tips, you can create a more ergonomic and comfortable fit:
Adjust armrests. Improperly positioned or uncomfortable armrests can cause tension in the shoulders and neck. Set the armrests at a height that allows your arms to rest comfortably and maintain a relaxed posture.
Consider a footrest. A footrest promotes proper blood circulation and reduces stress on the legs and lower back.
Replace the wheels with smoother and better ones (for example). Sometimes the wheels can start to move poorly due to dirt or breakage. In this case, you should think about replacing them.
Eliminate the cause of the squeak. Sometimes when moving, the chair may creak, which causes discomfort. You can read more about how to do this here.
