Annoyed That Your Office Chair Keeps Sinking? 3 Easy Fixes

Introduction

If your office chair keeps sinking, you're not alone. This common issue can be frustrating, but there are simple solutions to fix it. In this guide, we'll explore three easy methods to stop your office chair from sinking, ranging from temporary fixes to a permanent replacement.

Chapter 1: Hose Clamp Method

This method is a quick and budget-friendly solution to prevent your chair from sinking. While it’s not the most aesthetically pleasing, it can effectively provide a temporary fix.

Steps to Follow

1. Adjust Chair Height

   • Raise your chair to the desired height. If it doesn’t lift easily, pull the lever and gently pull up on the chair simultaneously.

2. Clean the Area

   • Wipe the area where you will apply duct tape and the hose clamp with an old rag or paper towel.

3. Prepare Duct Tape

   • Cut a piece of duct tape approximately 6 to 8 inches long.
   • Wrap it around the cylinder at the thicker part to help the hose clamp grip better.

4. Apply Hose Clamp

   • Loosen the hose clamp fully and wrap it around the cylinder.
   • Use a flat blade screwdriver to tighten it into a circle.

5. Position and Tighten

   • Ensure the clamp is positioned at the bottom of the cylinder where it meets the thicker outer column.
   • Tighten the hose clamp securely to prevent sinking when you sit.

Practical Tips

• This method is temporary; it may loosen over time. If the chair starts sinking again, repeat the process.

Chapter 2: PVC Spacer Method

This method is slightly more permanent than the hose clamp and provides a better aesthetic, though it remains non-adjustable.

Steps to Follow

1. Adjust Chair Height

   • As before, raise your chair to the desired height, pulling up on the chair if necessary.

2. Measure the Gap

   • Measure the distance between the cylinder column and the chair seat. For example, this distance could be around 3 to 3.5 inches.

3. Get a PVC Spacer

   • Obtain a PVC pipe or spacer that matches the measured distance.

4. Remove Cylinder Column

   • Lay the chair on its side.
   • Use a flat blade screwdriver to remove the clip and washer at the bottom of the cylinder.
   • Pull the chair base and cylinder column straight out.

5. Install the PVC Spacer

   • Slide the PVC spacer onto the cylinder.
   • Ensure that any components, like bearings or washers, are replaced correctly.

6. Reassemble the Chair

   • Reattach the cylinder column and base.
   • Replace the washer and retaining clip, ensuring everything is secure.

Practical Tips

• This method is more stable than the hose clamp but still lacks adjustability. Ensure all components are reassembled correctly to avoid any issues.

Chapter 3: Replace Chair Cylinder Entirely

Replacing the chair cylinder is the most reliable and professional solution. While it may cost around $30, it provides a permanent fix with full adjustability.

Steps to Follow

1. Lay Chair on Its Side

   • Position the chair for easier access to the cylinder.

2. Remove Old Cylinder

   • Use a flat blade screwdriver to take off the retaining clip and washer at the bottom.
   • Pull the chair base and cylinder column straight out.

3. Use a Cylinder Removal Tool

   • Place the first shaft collar around the cylinder piston and tighten it slightly, allowing it to slide up and down.
   • Add the second shaft collar next to the first and tighten it securely.

4. Extract the Old Cylinder

   • Use extraction screws to grip the first collar. As you tighten them, the cylinder will begin to move.
   • Continue tightening until the cylinder pops out.

5. Install the New Cylinder

   • Test the new cylinder by pressing the button on top to ensure it extends properly.
   • Insert the new cylinder into the chair base and reattach the chair base.

6. Final Assembly

   • Flip the chair back upright and test the new cylinder for lift and adjustability.

Practical Tips

• For a hassle-free experience, consider purchasing a cylinder replacement kit that includes all necessary components.

Conclusion

Each of these methods provides a viable solution to your sinking office chair problem. For a temporary fix, use the hose clamp method. For a more permanent yet aesthetically pleasing solution, try the PVC spacer. Finally, for the best long-term results, replacing the chair cylinder is highly recommended. Choose the method that best fits your needs and enjoy a more stable seating experience!
