Definition
The padded, cushioned, and fabric- or leather-covered materials used to finish the interior seating and trim of an aircraft cabin, including seat cushions, backrests, armrests, side panels, and headliners.
Plain English
The soft covered materials that make up the seats and interior padding of an aircraft cabin.
Context Anchor
Seen during aircraft interior inspections, seat repairs, cabin refurbishment, and preflight checks for loose or damaged interior material.
Derivation
From the older English word 'upholder', meaning a person who repaired or held up furniture. Over time it came to mean the trade of fitting cushioned coverings, and now refers to the padded interior materials themselves.
Why Pilots Care
Aircraft upholstery must meet specific flammability standards set by the FAA. Replacing seat covers or padding with non-approved materials can make the aircraft unairworthy, even if the new material looks identical.
Intuition Check
Do not think of upholstery as only decoration. In an aircraft, it is part of the installed interior and can affect safety, inspection condition, and approved equipment status.
Example Sentence 1
After years of wear, the owner had the cabin upholstery replaced with FAA-approved fire-resistant materials.
Example Sentence 2
New upholstery material was installed to replace the faded covering on the cabin sidewalls.
