Here are some easy tips to fix an office chair that won’t stay up.

1. Replace the pneumatic cylinder

An office chair uses an air compressing mechanism commonly known as a pneumatic cylinder to adjust the seat’s height. When you change the height, the internal control valve adjusts pressure in the gas cylinder, causing the chair to move up or down.

As such, if your office chair keeps sinking, then it means that the cylinder is not functioning correctly. Ensure you find out the gas cylinder type your chair uses before buying one.

But it is relatively easy to find a generic replacement that will work with your office chair. Then look for an online tutorial for replacing gas cylinders. This method will increase the lifespan instead of it ending up in a landfill. It will also help your office chair just like a new chair.

2. Fixate the chair height

This entails using one of two methods to ensure the chair stays in place and does not move up or down. It will hinder chair height adjustment, but it is the cheapest way to ensure that your chair does not keep sinking.

Method 1: PVC pipe method

• Measure the length of the chair cylinder and the diameter of the cylinder.
• Then get a PVC pipe that is slightly larger than the cylinder diameter and cut it to size.
• Ideally, you should cut it at a height that suits your seating needs. But you can always add an extra PVC pipe piece to adjust the height.
• Then cut a slit into the pipe lengthwise and install it over the PVC like a cover.
• Make sure you use a thick gauge PVC pipe to stay in place and support the chair base efficiently.

Method 2: Jubilee clip or hose clamp method

• Get a jubilee clip or hose clamp that is big enough to cover the gas cylinder’s diameter.
• You will also require a screwdriver and duct tape.
• Set your seat to the preferred height, then use the clamp or jubilee clip to clamp the seat in place.

Too much strain on it can be harmful to your back with time. The following tips will help stop the office chair from leaning back.

Why your office chair leans backward?

Your desk chair leaning backward is due to the following reasons;

• Broken or damaged casters especially those at the back
• Loose or bent seat plate
• Change in the tilt tension

How to fix the problem

Follow these steps to fix the issue:

Inspect for any damaged caster

If the casters are deformed or broken, especially at the back, the chair will lean in that direction. All casters should touch the floor and be at the same level.

They usually break due to uneven weight distribution on the seat or manufacturing technical issues.

• If a caster is damaged, you should replace it. It is impossible to buy one caster, consult your manufacturer on buying a matching set.
• Use a screwdriver to remove the broken casters from their sockets.
• Apply a little amount of spray lubricant at the base of each socket, to help reduce friction as you fix the new casters
• In case you don’t have a lubricant, use petroleum jelly like Vaseline.
• Drive in the new casters into its socket using a rubber mallet by tapping gently or a little push with your hands.
• Test your chair if it’s still leaning.

Examine your seat plate

• Lay your chair on the side to check the seat plate. It is black, painted steel under your chair.
• Tighten any loose screws, replace the missing ones, and test if the chair still leans. If the chair again tilts backward, you should replace the seat plate.
• Ensure you order the appropriate match for your chair brand that will fit and replace the deformed one.

Adjust the tilt tension in your chair

• Sit on the chair with your feet on the floor and your back positioned on the backrest.
• Push the knob under an office chair and tilt the seat forward, then release it.
• Push the tilt adjustment down, release the knob, ensure your chair is in a reclined position, and your feet touch the floor.
• If the position is comfortable, lock my office chair.

Conclusion

Try the above-explained tips in fixing your chair, but if they don’t work, it is a high time you plan on purchasing a new office chair. It may be too expensive to fix a new seat plate and caster, and still, they don’t work so before purchasing consult and weigh your options.
