Frequently Asked Questions

Q: What size five-star chair base do I need for my office chair?

A: The right size depends on your chair's seat width and intended use. For compact stools without backrests, the 24cm radius base is ideal. Standard office and computer chairs typically work best with the 30cm radius base, while larger chairs (without a reclining function) are suited to the 32cm radius option. Measure your existing base from center to the tip of one arm to confirm the best fit.

Q: Are the casters included with every SKU?

A: No — casters are only included with SKUs 2, 4, and 6. SKUs 1, 3, and 5 include the aluminum alloy base only. If you need rolling casters, select an even-numbered SKU that corresponds to your required base size.

Q: Is this chair base compatible with standard gas lift cylinders?

A: Yes. This five-star base is designed to fit most standard pneumatic gas lift cylinders (also called air cylinders or chair pistons) used in the majority of office, gaming, and computer swivel chairs. If you are unsure about compatibility, check the diameter of your existing cylinder before ordering.

Q: How much weight can the aluminum alloy five-star base support?

A: The thickened aluminum alloy construction is engineered for heavy-duty use, providing excellent load-bearing capacity for everyday office and gaming applications. For specific weight ratings, please refer to your assembled chair's manufacturer guidelines, as the total capacity also depends on the gas cylinder and seat components used.
