A wobbly swivel chair can be a frustrating distraction, especially when you’re trying to focus or relax. And over time, even the best office chair or lounge chair can become unstable due to loose screws, worn-out parts, or uneven flooring.
But don’t worry—there’s no need to toss out your favorite chair just yet!
With a few simple DIY fixes, you can easily stabilize a wobbly swivel chair and restore it to its original sturdy state.
In this guide, we’ll walk you through practical, step-by-step solutions that anyone can tackle, no matter your skill level. From tightening bolts to replacing faulty parts, you’ll have your chair wobble-free in no time!
Why Do Swivel Chairs Become Wobbly?
Swivel chairs are designed to provide comfort and mobility, but with time, regular use can cause them to become unstable.
Here are a few common reasons why your swivel chair might be wobbling:
- Wear and Tear: Daily use causes the screws, bolts, and other components to loosen or wear out over time, making the chair feel less stable.
- Loose Screws or Bolts: Swivel chairs are held together by screws and bolts, and when these loosen, the chair can start wobbling.
- Faulty Base or Gas Cylinder: The base and gas cylinder (the part that controls height adjustment) can sometimes malfunction or wear out, leading to instability.
- Uneven Legs or Casters: If the casters (wheels) or legs of the chair are uneven or damaged, the chair may not sit flat, causing it to wobble when you move.

Step-by-Step DIY Solutions to Stabilize a Wobbly Swivel Chair
A wobbly chair can throw off your focus, not to mention it might even be a little dangerous if not fixed. Here’s how to fix that wobbly chair in no time:
Tighten Screws and Bolts
The most common reason for a wobbly chair is loose screws or bolts. Thankfully, this is also the easiest fix.
How to Fix:
- Flip your chair upside down and inspect the screws and bolts that connect the base to the seat.
- Use a screwdriver or Allen wrench to tighten any loose screws or bolts. Be sure to check all connections, even the ones you didn’t think were loose.
- Once everything is secure, sit in the chair to test for stability.
Why It Works: Tightening the screws and bolts restores the chair’s original structure, preventing unnecessary movement.
Check and Fix the Chair Base
The base of the chair is responsible for holding everything together, and if it becomes damaged or loose, your chair will wobble.
How to Fix:
- Inspect the base of the chair, looking for any cracks, damage, or bent parts.
- If the base is damaged, it might need to be replaced. Contact the manufacturer for a replacement part or purchase a compatible base online.
- Ensure the base is securely attached to the chair post. If it’s loose, tighten the connection using a screwdriver or wrench.
Why It Works: A stable base is essential for keeping the chair balanced and wobble-free.
Replace Worn or Uneven Casters
Casters (the wheels on the bottom of your chair) can wear out or become uneven over time, causing the chair to wobble when you move.
How to Fix:
- Remove each caster by pulling it out of the base or unscrewing it, depending on the model.
- Check the wheels for signs of wear, such as flat spots or cracks.
- If the casters are damaged, replace them with new ones. You can purchase replacement casters online or at an office supply store.
- Make sure all the casters are evenly installed.
Why It Works: Replacing worn casters ensures that the chair moves smoothly and stays balanced.
Stabilize the Gas Cylinder
A faulty or worn-out gas cylinder can cause your chair to sink or wobble unexpectedly.
How to Fix:
- Test the gas cylinder by adjusting the chair’s height. If the chair sinks or feels unstable, the cylinder may be malfunctioning.
- To replace the gas cylinder, first remove the old one by turning the chair upside down and using a rubber mallet to gently tap it out of the base.
- Install the new gas cylinder according to the manufacturer’s instructions, making sure it is securely attached.
Why It Works: A functional gas cylinder ensures that the chair’s height remains consistent and stable.
Add Rubber or Felt Pads to the Base
If your chair’s base isn’t gripping the floor properly, adding rubber or felt pads can help stabilize it and prevent slipping.
How to Fix:
- Purchase rubber or felt pads from a hardware store.
- Attach them to the underside of the chair’s legs or base.
- Ensure the pads are evenly spaced to maintain balance.
Why It Works: Rubber and felt pads create friction with the floor, preventing the chair from moving or wobbling unnecessarily.
Lubricate Moving Parts
Sometimes, friction between moving parts can cause uneven wear and wobbling. Lubricating the swivel mechanism can help.
How to Fix:
- Apply a lubricant like WD-40 to the moving parts, especially where the base meets the chair post.
- Rotate the chair a few times to ensure the lubricant spreads evenly.
Why It Works: Lubricating the moving parts reduces friction, allowing for smoother swiveling and reducing wobble.
Fix Loose Wooden Joints (For Wooden Swivel Chairs)
Wooden swivel chairs can develop loose joints over time, which can cause instability.
How to Fix:
- Identify the loose joints by gently rocking the chair and observing where movement occurs.
- Apply wood glue to the loose joints and clamp them in place while the glue dries.
- Once dry, reassemble the chair and check for stability.
Why It Works: Tightening and securing loose wooden joints restores the chair’s structural integrity.
Preventative Maintenance Tips
Once you’ve stabilized your chair, regular maintenance will help prevent future wobbling. Here are some tips to keep your chair in top shape:
- Regularly Tighten Screws and Bolts: Check and tighten screws and bolts every few months to ensure everything stays securely in place.
- Inspect Casters: Casters can wear out over time, so check them regularly and replace them when needed to maintain smooth movement.
- Lubricate Moving Parts: Apply lubricant to the swivel mechanism and other moving parts periodically to keep everything operating smoothly.
- Check the Base and Gas Cylinder: Inspect the base and gas cylinder once a year to ensure they are in good condition. If they show signs of wear, replace them before they cause instability.
Concluding Words
Stabilizing a wobbly swivel chair doesn’t require expensive repairs or professional help. Instead, with just a few tools and some DIY know-how, as above-mentioned, you can fix the most common causes of wobbling and restore your chair’s stability and comfort.
So, whether you need to tighten some screws, replace a caster, or lubricate the moving parts, these simple solutions will help you keep your chair in great condition—without the frustration of a wobbly chair!
