What Will You Need?

Before you begin assembling your office chair, ensure you have all the necessary items. Here is a list of things to check off before getting started:

  • The instructions (all models of chairs require different types of assembly)
  • A Phillips head screwdriver
  • Different sizes of Allen wrenches
  • Adjustable pliers or vice grips
  • An adjustable wrench (optional but may come in handy)

Once you have everything that is required for assembly, it’s time to begin.

10 Easy Steps on How to Assemble Office Chair

Step 1: Read the Instructions Carefully

Make sure to read through all the instructions that come with your office chair. Different models require different types of assembly, so following the correct steps is essential for successful assembly. It’s also helpful to have a clear understanding of what tools and parts you will be using – this way, you can quickly identify if something needs to be added or corrected.

Step 2: Gather Your Tools

Gather all the tools mentioned in the previous section so they are within easy reach when needed. This includes a Phillips head screwdriver, different sizes of Allen wrenches, adjustable pliers/vice grips, and an adjustable wrench.

Step 3: Place the Frame Together

Take out the parts of the chair frame (also called a base) and lay them on a flat surface like a table or floor. Read the instructions carefully for specific assembly directions as different models may require unique steps. Generally, you will begin by placing the frame together and attaching the wheels.

Step 4: Attach the Wheels

Now it’s time to attach the wheels to your chair. Find the small screws or clips that hold them in place, then use a screwdriver or Allen wrenches, depending on what type of attachment is required for your model of chair. Use adjustable pliers or vice grips to firmly hold the wheel in place as you tighten the screws.

Step 5: Attach the Arms

Most office chairs come with arms, and they must be attached before moving on. Find where they fit onto the frame (often at the base of the seat) and use a screwdriver or Allen wrenches to attach them. Be careful not to overtighten the screws, as this could damage the frame.

Step 6: Attach the Backrest

Now it’s time to attach the backrest to the chair. This part of assembly can be tricky, so make sure that you read through the instructions carefully and double-check every step before moving on. Use an adjustable wrench (optional) to hold the backrest in place as you use a screwdriver or Allen wrenches to tighten the screws.

Most Office Chairs Come With Arms

Step 7: Connect the Seat to the Frame

The next step in the assembly process is to connect the seat to the assembled frame. The seat typically has pre-drilled holes that align with holes on the top of the frame or base. Position the seat onto the base, ensuring the holes are properly lined up.

Now, insert the screws provided and use your Allen wrenches to tighten them. Remember, do not overtighten to avoid damaging the chair. Once the seat is secure, gently shake it to ensure it’s firmly attached and stable.

Step 8: Attach the Gas Lift Cylinder

This step involves attaching the gas lift cylinder, which allows for height adjustment of the chair. Locate the cylinder and insert it into the hole at the center of the wheelbase. It usually fits right in without needing screws, but ensure it’s secure.

Next, place the plastic cover (if provided) over the cylinder for aesthetic purposes. This step is typically straightforward but refers back to the instructions if you find it challenging, as some models might have unique assembly requirements for this part.

Step 9: Attach the Chair to the Gas Lift Cylinder

After securing the gas lift cylinder, it’s time to attach the chair. In most models, the chair is simply placed on top of the gas lift cylinder. Ensure the chair is positioned correctly (usually with the controls facing forward) and slide it onto the cylinder.

It should fit snugly but move freely for height adjustment. This step doesn’t typically require any tools but refers to the instructions if necessary. Once the chair is attached, test it by gently raising and lowering the seat to ensure it functions correctly.

Step 10: Final Adjustments and Testing

Attaching the Gas Lift Cylinder

The last step involves making final adjustments to the chair and testing it out. Check the tension of the seat’s tilt mechanism, and adjust if necessary to suit your comfort. More often than not, there’s a knob underneath the seat that controls this feature. Also, adjust the chair’s height and armrests, if applicable, to fit your desk and personal preference.

Following these ten steps, you should have a comfortable chair and can get to work!

5 Things You Should Avoid

  1. Avoid Skipping the Instructions: Don’t assume all chairs are the same even if you’ve assembled a chair before. Always read the instructions first to understand the unique assembly requirements of your specific model.
  2. Avoid Forcing Parts Together: If a screw doesn’t fit or a piece doesn’t slot in as it should, don’t force it. This can lead to damage. Recheck the instructions and ensure you’re using the right part in the right place.
  3. Avoid Over-Tightening Screws: Over-tightening can strip the screw holes or damage the chair parts. Tighten just until the part is secure and does not wobble.
  4. Avoid Using Wrong Tools: Always use the correct and recommended tools for assembly. Using the right tools can protect the parts and make the assembly process easier.
  5. Avoid Rushing: Assembly isn’t a race. Take your time to ensure everything is done correctly. Rushing can lead to mistakes or damage.

Avoiding these five common mistakes will help ensure your chair is properly assembled and functional. With the right tools, a little patience, and following the instructions, you’ll have an office chair that is comfortable and ready to last!

The Lever on the Side of a Chair

How Do You Adjust a Chair Lever?

The lever on the side of a chair is designed to adjust the angle and tilt of the seat. To adjust this, first, locate the lever; most models have it placed just beneath one of the armrests.

Pull up or push down on the lever depending on whether you want to raise or lower your chair’s angle. You can also twist or counterclockwise to adjust the seat’s tilt. Small adjustments can be made by pressing and holding down on the lever.

Once you’ve adjusted the chair to your desired position, release the lever and test out how it feels. Adjust further if necessary until you get a comfortable seating angle and tilt. That’s all there is to adjusting the chair lever!


With the right tools and step-by-step instructions, assembling an office chair is easier and more manageable than you might think. And, now that you know how to assemble office chair properly, the process will become second nature the next time.

Whatever your needs for an office chair, understanding and following the assembly guide will ensure that everything fits together pleasantly—making it just as much a pleasure to admire as it is to use.
