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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Will this aluminum alloy base fit my existing gas-lift cylinder?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Do the caster wheels work on hardwood floors?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the aluminum alloy base strong enough for heavier users?\u003c\/h4\u003e\n\u003cp\u003eA: 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.
