Disassembling an office chair is a child’s play. However, if you wish to deconstruct a chair with the hope of reassembling it in the future, you need to follow a detailed guide that explains how to dismantle it without damaging the chair.

We request users to understand their design model and its features, as many chairs have a few different parts that need to be addressed separately.

With that being said, let’s get to the article and help you deconstruct your favorite office chair without a single scratch or dent!

Reasons To Disassemble An Office Chair

While many people never think of disassembling an office chair, there are many occasions where you might need to perform this same task without any formal notice.

Below are a few reasons why one may need to disassemble their hydraulic chair.

  • Shifting: There may arrive a moment when you might need to relocate your furniture to another place. Accommodating such a bulky and space-consuming article in your shifting vehicle isn’t the most practical way of transporting it. To safely save on space and transport your comfy office chair, you must dismantle it before loading the chair in the vehicle.
  • Returning to the manufacturer: You might need to dismantle your hydraulic office chair if you receive a damaged product. One cannot ship the chair as is and need to deconstruct and make it flat to ship it according to the shipping regulations. The buyer is liable for improper dismantling, further resulting in any damage while shipping, so proper disassembly is a sine qua non.
  • Changing the gas cylinder: Most office chairs need a gas cylinder change every few years. If you’re unable to adjust your chair’s height, then chances are your gas cylinder is damaged and needs to be replaced. Deconstructing and replacing the cylinder yourself will surely be less time-consuming and tedious when you know how to deconstruct it properly.

Step-By-Step Guide

Step-By-Step Guide

With proper step-by-step guidance, you can very quickly take on the task of dismantling your office chair within minutes.

We recommend following the below-mentioned steps in the correct order for a smooth disassembly.

Dismantling the headrest

Before starting, lay down a rubber sheet or old yoga mat to avoid any surface scratch on your floor or table.

Since the headrest is the most externally attached part, we highly recommend starting with it and taking it out of the way.

Most headrests are connected to any office chair with 2 or 4 simple screws. You need to remove the screw cover plates and unscrew all the bolts attached to the chair.

Do not forget to stick the screw cover plates into the chair to avoid looking at the screws once you reassemble your chair.

Removing the casters

To remove all four casters, plop the office chair upside down and wiggle the joint base.

Most casters are attached without any screws, so that simple twist-and-turn action can separate the caster from the chair. You may use a little WD-40 to lubricate the joints for easy removal.

Addressing the backrest

The backrest of each chair is attached in different places, but most manufacturers follow the model design of attaching their backrest underneath the sitting frame.

You can quickly locate the joint once you plop your chair upside down. From there, use an Allen wrench or a plain screwdriver to remove the big bolts from the sitting part.

Unfastening the bolts will automatically separate your backrest within a second.

Disassembling both the armrests

Since most armrests are built in various shapes, you need to be extra careful about the joints and primary connection.

Sometimes you might need to unscrew at multiple places so remembering the sequence is exceptionally important. Once you are done with the screws, make sure to remove any additional washers or plates.

If your chair is just attached in a slot without any screws, you can easily remove it with a bit of force.

Remove the star-shaped base

Removing the star-shaped base frame is exceptionally important before removing the most crucial component of any office chair – the gas cylinder.

You can use a rubber mallet to dislodge the base from the middle frame. Generally, removing the bottom does not require brutal force.

Separating the gas cylinder

Before you initiate the final step, always remember that dismantling any gas cylinder should be done with intense care, as a single wrong push or amount of pressure can damage the gas cylinder.

It would be best to cover your pipe wrench’s mouth with a piece of duct tape. This extra tape prevents the pipe from having any dents while providing additional grip.

Use your pipe wrench and clamp down the tube at the base. Once the pipe-wrench has gotten a proper hold, consider moving it on both sides to loosen the pipe from the seat.

There are no screws or locking mechanisms, so using a clamp is your only way.

If that’s not the case with your model, you need to perform the final step of hitting the base with a mallet to dislodge the gas cylinder from the office chair’s base.

With this, you have successfully dismantled your chair!

Can You Reassemble An Office Chair?

Can You Reassemble An Office Chair?

Now that you have detached your chair pieces, you must be wondering if you can carry on the task of assembling the office chair.

The answer is yes; you can reassemble any office chair without any external help. The most important thing is remembering the sequence of the deconstruction process.

It will help if you start by attaching your gas cylinder and moving upwards until you finally secure your headrest.

We assure you that your reassembly will be smoother and quicker if you follow the steps correctly.

If, however, you aren’t sure about the flow or feel you might mess with the screw placements, consider recording your dismantling process.

Additionally, referring to the manual can work in your favor if your chair’s model is a tad bit complicated.

Suggestions And Tips To Consider

Suggestions And Tips To Consider

Before initiating the process, we highly recommend glancing these tips and suggestions for a smooth disassembly:

Abstain dismantling unnecessary parts

Not all chairs are constructed using the same frame or assembly requirements, so we highly suggest abstaining from dismantling any unnecessary parts.

For instance, you do not need to remove all the details of your armrest. Just detaching the primary connection is enough; additionally, it will help you reassemble the chair that much quicker.

Keep all the required tools handy

One does not need a bag full of equipment to dismantle any chair, but you surely need some primary tools to get the job done.

Don’t worry if you do not possess any power tools, as the process requires a few necessary tools. We highly recommend a screwdriver, Allen key, hammer, or rubber mallet to take on the task of disassembly.

Additionally, using a tiny spray of WD-40 would pose no harm and make the process much smoother. Lastly, consider WD-40 an essential requirement if your office is old or has rusty screws.

Remember the sequence and screws

Familiarize yourself with all the parts as you should be able to identify any piece of chair in an instant.

Similarly, it would be best to remember the sequence of your disassembly, and it is ideal to start your assembly in the complete opposite series.

Always pay close attention to the screws and only attach them where they originally were. We recommend opting for tiny boxes or Ziploc bags to avoid any confusion.

Name each box according to the part, e.g., backrest, headrest, and store the screws in those named bags.

Disassembling the cylinder is demanding and strenuous

As mentioned earlier, one needs to be careful while disassembling your gas cylinder. Since dislodging the cylinder is strenuous, most people apply an extreme external force that damages the cylinder.

A simple wrench and rubber mallet will work if you use the proper technique with the correct pressure. The rest of the parts are comparatively easy to remove, so carry this step with care.

Reference the instructional manual or contact the manufacturer

Suppose you are having a hard time dismantling your office chair. In that case, we highly recommend referring to the instructional manual.

If, however, you do not have the manual, consider checking for an online manual. Most manufacturers have a detailed soft copy of manuals on their website.

Similarly, if you are stuck at some point, don’t be afraid to contact the manufacturer via their customer care number.


With that, we have come to the end of our chair dismantling guide. We hope our step-by-step instructions will help you disassemble the chair with precision.

However, ensure that you strictly remove the parts in the steps mentioned above. We assure you that your reassembly will also be breezy if you note down the screws and tiny details with care.

Finally, while reattaching, you need to sit on your chair and apply pressure to lock the gas cylinder to keep the fitting tight.
