Why Replace Your Chair Base?

A worn or broken chair base affects posture support, stability, and floor protection. Replacing just the base is a cost-effective and eco-friendly alternative to buying a whole new chair. Whether you're refurbishing a beloved executive office chair or upgrading a gaming setup, this aluminum alloy five-star base delivers the structural integrity you need.

Frequently Asked Questions

Q: How do I know which five-star chair base size is right for my chair?

A: Measure the tip-to-tip span of your existing base. A 24cm radius base (48cm tip-to-tip) suits compact backless stools; a 30cm radius (60cm tip-to-tip) fits most standard office and computer chairs; a 32cm radius (64cm tip-to-tip) is ideal for larger chairs without a reclining mechanism. When in doubt, size up for extra stability.

Q: Will this aluminum alloy base fit my existing gas-lift cylinder?

A: Yes — this base uses the standard tapered gas-lift cylinder socket found on the vast majority of office, computer, and e-sports chairs. Simply remove your old base, insert your existing gas cylinder into the new hub, and you're ready to go. No tools or drilling required.

Q: Do the caster wheels work on hardwood floors?

A: The standard black/white caster wheels included in select SKUs are designed for general use on both hard floors and low-pile carpet. If you have delicate hardwood flooring, we recommend using protective floor mats or choosing a set of soft PU caster wheels (sold separately) for added floor protection.

Q: Is the aluminum alloy base strong enough for heavier users?

A: The thickened aluminum alloy construction is designed to handle the load demands of typical office and gaming chairs. The material offers an excellent strength-to-weight ratio, resisting bending and deformation under sustained daily use. Always ensure your selected SKU matches your chair's size and intended use.
