Contrast material computer 1 nylon plastic chair Ipomoea feet 2 feet of steel iron feet Aluminum Alloy 3 feet, which is good and practical why
Computer chairs are best equipped with what you call "steel iron feet" (in fact, iron plating outside), the biggest feature is durable and affordable.
And plastic feet may match a chair, but it's too weak to break. The aluminum alloy is more expensive (if your computer chair is a Guangdong chair can be used)
