Does your chair sink down throughout the work day? Is it difficult for you to adjust your chair either up or down? If you are having these issues, you may need to replace the gas cylinder on your office chair in order to get it to function properly once again. This is actually a pretty simple process. Materials you will need:

  1. A rubber mallet
  2. A pipe wrench or a screw driver
  3. A replacement cylinder—you can request a new one by contacting NBF’s customer service at 1-800-558-1010 or online.
  4. WD-40—only necessary for older chairs or when you are having a difficult time removing parts of the chair.

Step 1: Tip the chair onto its side.

Step 2: Use the rubber mallet to tap the base of the chair away from the seat of the chair. Do this until you can easily remove the base from the rest of the chair.

Step 3: The cylinder will be left. Use the pipe wrench to clamp tightly onto the top of the cylinder and twist and then pull up in order to remove the cylinder. If a pipe wrench is unavailable, you can unscrew the main bolts at the bottom of the seat in order to remove the mechanism from the chair. Then simply use your rubber mallet to tap the mechanism away from the cylinder, thereby separating the cylinder from the mechanism of the chair. If it is difficult at any point to remove these parts in step three, you may need to apply WD-40 to the joints and let it sit for a few minutes. Be sure to protect surrounding surfaces and chair fabrics before applying the WD-40.

Step 4: Now that the cylinder has been removed, you can replace it with the new one. Insert the bottom of the cylinder into the center of the chair base.

Step 5: Carefully lift both the chair base and the chair cylinder into the chair mechanism. The parts will then fasten on their own. See the video above in order to see the steps in action.
