How to Repair Computer Chairs
That's a great way to break an office chair. (Creatas Images/Creatas/Getty Images)

Office chairs are made up of several components, with as many as 14 separate adjustable parts in some higher-end chairs. Many things can go wrong. Some problems, such as a sticky wheel or a wobbly back, have simple solutions. However, more complicated equipment breakdowns, such as problems with hydraulic adjustments, require some level of knowledge and expertise, not to mention special replacement parts.

    Wobbly Seat Back

  1. 1

    Tighten the bolt on the back of the chair to fix a wobbly seat back.

  2. 2

    Flip the chair over if the lever that adjusts the seat back is not working.

  3. 3

    Bolt a small piece of plywood to the bottom of the chair using the existing holes. This will prevent any backward and forward swaying of the chair caused by a loose spring, according to Swivel Chair Parts.

    Broken Chair Wheel

  1. 1

    Flip the chair over so that the wheels are sticking in the air.

  2. 2

    Remove any debris that might be stuck in the problem wheel. There may be a pebble or some other object causing the problem, in which case you can dislodge it using the screwdriver.

  3. 3

    Lubricate the wheel's axle rod using WD-40 spray. Sometimes rust or grime may cause the problem.

  4. 4

    Remove the wheel if none of these steps work. The axle might be badly damaged or bent, so just pop off the wheel by pulling or, in some cases, using the screwdriver to unfasten. By shining the flashlight inside the wheel, you should be able to look at the wheel rod and lubricate it more accurately. If the rod appears bent, you will need to replace it by taking the wheel into an office supply store.

    Broken Hydraulic Lift or Adjustment

  1. 1

    Flip the chair so that the wheels are in the air.

  2. 2

    Remove the base of the chair by loosening and removing the small black base retaining clip and the washer on the centre underside of the base. This will leave only the bottom part of the gas cylinder responsible for height adjustment.

  3. 3

    Twist the cylinder, using the pipe wrench, to loosen it. You may need to spray the cylinder with WD-40 to help loosen it.

  4. 4

    Remove the defective cylinder once it is loosened and take it to the office supply store for replacement.

  5. 5

    Reverse these steps to install the new cylinder. These same steps apply if hydraulic cylinders are used in any of the other adjustment mechanisms.
