9 Parts of a Computer Chair for Replacement

Every ergonomic office chair has specific parts, each with its individual functions. Do you notice something wrong with your chair but can’t explain it? Perhaps your chair is unable to move or you’re unable to readjust the seat position. What you need to do is learn the computer chair part names and figure out what each of them does.

There are nine parts of a computer chair you should know about. Once you do, a potential repair can be made easier. Familiarize yourself with these computer chair part names:

1. Arms

These parts are also known as T-arms. The main purpose of these parts is to rest your arms in a comfortable position. For remote workers, this is crucial to their typing. If your arms are broken, you need a viable alternative.

Height-adjustable variations allow you to flip them up or down whenever you need to. T-arms are an underrated aspect of computer chair parts accessories since they also keep your elbows position at a good angle. These are easy to install with a guide.

• Adjustability: If you need adjustable armrests, make sure the replacement parts offer height, width, and angle adjustments.
• Comfort: Look for padded armrests for enhanced comfort.
• Replacement Tip: Unscrew the old armrests and replace them with the new ones, ensuring they are securely attached and properly aligned.

2. Arm Pad

Every T-arm requires padding materials to make them more comfortable. The quality depends on the material used for the padding. For example, memory foam conforms to the shape of your arms. If it tears apart through usage, then consider getting a new foam replacement.

3. Headrest

Your head needs to be properly aligned with a straight back. Otherwise, you might be prone to cramps in your neck muscles. A headrest is applied to your chair with a bar. If the bar breaks, you can try to replace the bar rather than the headrest itself.

4. Support

One of the most important parts of an office chair is the lumbar support. How it works is it naturally curves your spine in the correct position. Lumbar support uses lower back cushioning so you can sit easier. Due to years of wear and tear, any replacements require a lumbar pad, which you can shop for online.

• Adjustability: Choose a lumbar support that offers adjustable height and depth to match your ergonomic needs.
• Material: Ensure the material provides adequate support and comfort.

5. Seat Pad/Pan

The seat pad is what cushions your hips between the chair base. Without it, it can be an uncomfortable experience sitting on a hard surface. Most seat cushions wear out over time, which lose their depth. You can always replace it with a compatible seat pad, depending on the product you buy. Memory foam is a good bet for higher quality service.

• Density and Support: Select a cushion with appropriate density and support to avoid discomfort during long hours of sitting.
• Size and Shape: Ensure the cushion fits the chair seat properly.
• Replacement Tip: Remove the old cushion and place the new one on the seat frame, securing it with screws or adhesive as needed.

For Chair Upholstery

• Material: Choose a durable and comfortable material, such as mesh, fabric, or leather. Consider breathability and ease of cleaning.
• Color and Style: Ensure the new upholstery matches your office decor.
• Replacement Tip: For a DIY upholstery project, remove the old fabric and padding, cut new fabric to size, and staple it securely to the chair frame. Consider professional reupholstering services for a polished finish.

6. Chair Cylinder & Cylinder Cover

One of the more critical parts of a computer chair is the cylinder. You use this object to move your chair up and down. There is also a cover to protect the cylinder from potential damage. If you can no longer do so, the cylinder might be broken and in need of repairs. These are relatively easy to replace since all it requires is separation with a wrench and a few screws. Always put a cover back in place when you finish.

• Weight Capacity: Select a gas cylinder that supports the user’s weight. Check the maximum weight rating of the cylinder.
• Height Adjustment: Ensure the new cylinder offers the desired height range. Measure the current cylinder’s extended and compressed lengths.
• Replacement Tip: To replace the gas lift cylinder, remove the chair base and use a pipe wrench to detach the old cylinder. Insert the new cylinder and reattach the base.

7. Chair Mechanism

The chair mechanism is what controls the tilt and tension of your chair. When it breaks down, you might notice how difficult it is trying to tilt forward. Repairs often involve heavy-duty replacements, since these tension and tilt mechanisms are slightly complicated. You also need to replace these when the part becomes too old to use.

• Replacement Tip: Remove the chair seat and base to access the tilt mechanism. Unscrew the old mechanism and replace it with the new one, ensuring all bolts and screws are tightly secured.
• Compatibility: Ensure the tilt mechanism matches the chair model and size.
• Adjustability: Look for mechanisms that offer multiple tilt options and tension adjustments.

8. Chair Base

One of the more identifiable computer chair parts accessories is the base. It’s a star-shaped bottom that connects the wheels on your swivel. If any of the wheels fall off, all you need to do is reattach them with compatible screws and a wrench; you don’t want to sit on a chair with broken wheels, after all, so prioritize your safety with these repairs.

Chances are if the chair base is broken, so might the cylinder that attaches your seat to the base. Consider the possibility of multiple repairs. Look for potential damages on the plastic coverings, since they offer visible signs.

• Material: Choose a durable material like metal or reinforced plastic, especially if the chair is used frequently.
• Compatibility: Ensure the new base is compatible with the chair’s gas cylinder and casters.
• Replacement Tip: Flip the chair upside down, remove the casters and gas lift cylinder from the old base, and attach them to the new base. Reassemble the chair.

9. Caster Wheels

The caster wheels are parts of a computer chair, especially on hardwood surfaces. These wheels are meant for you to slide across the floor without any trouble. However, the wheels can become stuck. If there is hair or strings in between the rims, it causes the wheel to stay in place. What happens is you can no longer slide properly.

Repairs typically involve you taking out the wheels with screws and a screwdriver. Once you do, you can clean the base of these wheels and remove any obstructions in between. All you have to do is put the castor wheels back together. Always keep in mind for objects on your floor.

• Compatibility: Ensure the new casters fit the chair’s base. Most casters are standard, but it’s wise to check the stem size.
• Floor Type: Choose casters based on your flooring. Hard plastic casters work well on carpets, while rubber or polyurethane casters are better for hard floors to avoid scratches.
• Replacement Tip: Remove the old casters by pulling them out or using a screwdriver for leverage. Insert the new casters by pressing them into the base until they click into place.
