Frequently Asked Questions
How do I know if a base or mechanism will fit my chair?
Measure the parts on your chair before ordering: caster stem diameter and length, gas cylinder diameter (or whether it’s tapered), the bolt pattern of the seat plate (if replacing the tilt mechanism), and the seat post receptacle. Compare these to the product specs—most replacement listings include caster stem size, gas cylinder hole diameter, and bolt pattern dimensions.
Can I install these parts myself without professional help?
Yes. Most buyers install bases, casters, and tilt plates with basic tools and the instructions provided. Swapping a base or casters typically takes a few minutes; replacing a tilt mechanism is a bit more involved but doable with a screwdriver and wrench. If you’re unsure, follow a step-by-step video for your chair type.
Will replacing a base or mechanism actually extend my chair’s lifespan?
In most cases yes. Replacing worn casters, a broken base, or a failed tilt mechanism restores original functionality and stability, delaying or avoiding the need for a full chair replacement. Choose sturdy metal parts and proper fit to ensure the repair lasts under your usage patterns.
