While office chair repairs often focus on mechanical parts like wheels or gas cylinders, cosmetic elements such as gas lift covers and plastic trim pieces play a major role in both aesthetics and function. These components keep the chair looking neat and help protect internal parts from dust and debris. If your chair’s plastic parts are cracked, loose, or missing, replacing them is a quick and affordable fix that makes your chair look brand new again.
What Are Gas Lift Covers and Trim Pieces?
Gas lift covers are telescoping plastic sleeves that hide the metal cylinder between the seat and the chair base. They compress and expand as the chair height is adjusted, keeping the lift mechanism protected and visually clean.
Trim pieces include various plastic components around the seat base, arms, or backrest. These parts may cover bolts, provide smooth edges, or give the chair a more polished look. Over time, these plastic pieces can crack or fall off due to impact, heat exposure, or aging.
Why Replace Them?
– Improve the look of your chair
– Prevent dust or debris from damaging internal parts
– Restore protective elements that may affect safety or stability
– Make resale or reuse more viable for older chairs
If your chair still functions well but looks rough around the edges, replacing damaged plastics is an easy upgrade.
How to Identify What Needs Replacing
Start by flipping the chair over and inspecting all visible plastic components:
– Is the gas lift cylinder exposed?
– Are any trim pieces missing or hanging loose?
– Do the armrest covers or base caps show cracks?
– Is the seat mechanism plate uncovered or surrounded by broken trim?
Make note of the parts and their approximate dimensions. You can find a variety of compatible office chair gas lift covers and replacement trim pieces on Amazon based on standard sizes.

Steps to Replace Gas Lift Covers
Step 1: Remove the Chair Base
Turn the chair upside down and gently pull the wheeled base off the gas cylinder. You may need to tap it with a rubber mallet if it’s stuck.
Step 2: Slide Off the Old Cover
The gas lift cover usually has multiple plastic segments that telescope. Pull off the entire cover or individual pieces from the cylinder.
Step 3: Install the New Cover
Take your new gas lift cover and slide it down over the cylinder, wide end first. Ensure the sections are properly nested and aligned.
Step 4: Reattach the Base
Push the wheeled base back onto the bottom of the gas lift and press down firmly until secure.
Replacing Other Trim Pieces
If you’re replacing armrest covers, base caps, or seat trim:
– Unscrew any fasteners or pry gently if it’s snap-fit plastic
– Measure the size and shape of the replacement needed
– Install the new piece using original hardware or double-sided adhesive if necessary
For example, you can find a range of armrest trim replacements or seat mechanism trims that fit most standard office chairs.
Tips for a Clean Replacement
– Wipe down exposed areas with a damp cloth before installing new covers
– Avoid over-tightening screws on new plastic parts
– Use plastic-safe lubricants if needed to ease installation
– Always double-check orientation before snapping or screwing parts into place
FAQs
Are gas lift covers universal?
Many are universal, but it’s best to measure your gas cylinder and check if the replacement has telescoping sections for flexibility.
Do I need to remove the entire gas cylinder to replace the cover?
No. Usually, you only need to remove the wheeled base. The gas lift can stay attached to the seat mechanism.
Can broken trim pieces affect chair function?
Sometimes. Missing trim can expose moving parts, sharp edges, or leave the seat plate unsecured. It’s good practice to replace broken plastics for both appearance and safety.
Where can I find trim parts if my chair brand isn’t listed?
Use keyword searches like universal office chair trim or match based on size rather than brand.
