How to Change the Gas Spring of an Office Chair?
Dealing with an office chair that sinks under your weight or creaks every time you move isn't just an annoyance; it's a genuine obstacle to a comfy, productive workday. The culprit behind these issues? More often than not, it's the gas spring or gas lift — the small yet pivotal component that lets you tweak the height of your chair. Over time, this mechanism wears out, leading to the need for a replacement.
In this article, we delve into everything you need to know about changing a gas spring for an office chair, from the lifespan of a gas spring and the telltale signs indicating it's time for a replacement, to a step-by-step guide on how to replace it. We'll also explore what to consider when purchasing a new gas spring, ensuring you make an informed decision.
How Long Does a Gas Spring Last?
On average, a quality gas spring in an office chair can last anywhere from 5 to 10 years under normal use. This estimate assumes that the chair is used for approximately 40 hours a week in a typical office setting.
The longevity of a gas spring is heavily dependent on the quality of its manufacture. Gas springs in premium office chairs, like the FlexiSpot BS4, are certified for performance and offer more cycles of extension and compression, thereby ensuring an extended lifespan.

The conditions under which the chair is used can also affect the lifespan of its gas spring:
1. Usage: The more frequently the chair is adjusted or the heavier the usage, the more wear and tear the gas spring undergoes. Improper use, such as frequently leaning heavily on one side, can also shorten the gas spring's effective lifespan.
2. Weight: Chairs that consistently support heavier weights may see a quicker decline in gas spring performance.
3. Environment: Exposure to extreme temperatures or corrosive substances can degrade the gas spring more rapidly.
While the gas spring may last for several years, its performance can degrade over time. This degradation can manifest as a slower response to height adjustments, a tendency to sink after being adjusted, or in some cases, a complete failure to support weight adjustments.
Signs to Change the Gas Spring of an Office Chair
While the lifespan of a gas spring gives a general idea of when a replacement might be needed, specific signs can alert you sooner to the need for attention. Here are the key indicators that it's time to consider changing the gas spring of your office chair:
1. Sinking Chair: One of the most noticeable signs is when your chair starts to sink slowly after being adjusted to a higher position. This gradual loss of height is a clear indication that the gas spring is no longer able to hold the weight it once could.
2. Difficulty Adjusting Height: If adjusting the chair's height becomes challenging, or if the lever seems unresponsive, it could mean the gas spring mechanism is failing. A functioning gas spring should allow for smooth and effortless height adjustments.
3. Visible Damage or Leakage: Any visible signs of damage to the gas spring, such as corrosion or leakage of the hydraulic fluid, are immediate red flags. These physical signs indicate that the integrity of the gas spring has been compromised, affecting its functionality and safety.
4. Noise During Adjustment: Unusual sounds, such as creaking or popping when adjusting the chair's height, can suggest that the gas spring is under undue stress or beginning to fail.
5. Instability: If the chair feels unstable, wobbles, or tilts unexpectedly when you sit or shift your weight, the gas spring's ability to maintain balance might be deteriorating. This instability can pose a risk to your safety and comfort.
Ignoring these indicators can lead to a complete failure of the chair's adjustment mechanism, potentially causing discomfort or injury. If you notice any of these signs, it might be time to invest in a new gas spring.
Should You Repair the Gas Spring of an Office Chair?
When faced with a malfunctioning gas spring in your office chair, you might wonder if a quick fix could get it back in working order. However, due to the complexities involved, the option to repair the gas strut in an office chair is often not viable.
Gas springs are sealed units that rely on pressurized gas and a precise mechanism to function. This design ensures smooth, controlled movement but also means that once they start leaking or get damaged, repairing them is nearly impossible for the average consumer. They require specialized tools and knowledge to handle the dangerous pressurized gas safely.
In many cases, the cost of the tools and the time investment required to repair a gas spring can exceed the price of purchasing a new one. Additionally, replacement gas springs are readily available and can be sourced to fit a wide range of office chairs.
Given these considerations, changing the office chair gas spring is generally the safer, more cost-effective, and most straightforward route to restoring your office chair's functionality and comfort.
How to Change the Gas Spring of an Office Chair?
Changing a gas pressure spring for an office chair might seem like a daunting task, but with the right tools and a bit of guidance, it's a process you can manage on your own. Follow these steps for a safe and effective replacement:
Step 1: Gather Your Tools
Before you begin, ensure you have the following items:
1. A new gas spring compatible with your chair model
2. A pipe wrench or a pair of vice grips
3. A rubber mallet or a hammer with a piece of wood (to protect the chair)
4. Safety goggles (recommended to protect your eyes from potential debris)
Step 2: Remove the Old Gas Spring
1. Secure the Chair: Turn the chair upside down to access the gas spring easily. It's helpful to have someone hold the chair steady or secure it against a table or workbench.
2. Detach the Base: Use the pipe wrench or vice grips to hold the gas spring's base. Gently tap the tool with a rubber mallet to loosen the base from the chair's seat mechanism. If your chair has a retaining clip instead of a screwed base, remove the clip with a flathead screwdriver.
3. Remove the Gas Spring from the Base: Once the base is loose, you should be able to pull the gas spring free. If it resists, gently tap on the base with a rubber mallet
while pulling it out.
Step 3: Install the New Gas Spring
1. Insert the New Gas Spring: Align the bottom of the new gas spring with the chair base. Ensure it's seated correctly and firmly. For chairs with a retaining clip, make sure the clip is securely fastened.
2. Reattach the Chair Base: Place the chair seat mechanism back onto the top of the new gas spring. Apply gentle pressure until it clicks into place, indicating a secure fi
t. If necessary, lightly tap the top with a rubber mallet to ensure it's fully seated.
Step 4: Test the Chair
1. Ensure Stability: Turn the chair right side up and sit gently to make sure the gas spring is functioning correctly. Adjust the height to test the smoothness of the mechanism.
2. Check for Leaks: After several adjustments, inspect the gas spring for any signs of leakage or unusual noise, indicating that it might not be properly installed.
If everything feels solid and operates smoothly, congratulations—you've successfully changed the gas spring in your office chair!
What Do You Have to Consider When Buying a New Gas Spring?
When you're in the market for a new gas spring for your office chair, there are a few key factors you'll want to keep in mind to make sure you're making the right choice.
Compatibility
1. Specificity: Gas springs are not one-size-fits-all. Verify the make and model of your office chair to find a compatible replacement. Many manufacturers provide detailed specifications or replacement parts specifically designed for their models.
2. Attachment Points: Check the attachment mechanism of your current gas spring (e.g., screw-in, clip-on) and ensure the new one matches. This ensures a seamless fit and installation.
Weight Capacity
Gas springs come with different weight capacities. Choose a gas spring that can comfortably support your weight to ensure durability and proper functionality. Opting for a gas spring with a weight capacity slightly higher than your current needs can provide a buffer for optimal performance and longevity.
Quality and Durability
High-quality materials such as steel or heavy-duty aluminum offer greater durability and longevity. Additionally, look for gas springs with a warranty. A warranty can serve as a confidence indicator of the product's quality and the manufacturer's support.
Safety Certification
Look for gas springs that carry safety certifications or marks, indicating that they have been tested for safety and performance. TÜV, BIFMA, and SGS certifications are widely respected in Germany and internationally for their rigorous testing procedures.
