Aluminum Office Chair Base | BIFMA & Standard Grade | Factory Direct
The ALB05 is a fine-polished aluminum office chair base available in two compliance tiers: a BIFMA-tested version for buyers shipping into markets with strict chair safety requirements, and a standard-grade version for buyers prioritizing cost where BIFMA certification isn't a market requirement. Same base structure, same finish quality - the difference is testing and certification cost, so you can choose the tier that matches your target market instead of paying for compliance you don't need.
Available in two sizes (R=330mm and R=350mm) with polished or chrome finish, this base is built for mid-to-high-end office chairs where finish quality is part of the product's perceived value, not just a structural afterthought.
Built for Buyers Who Need to Show Their Work
Choose Your Compliance Tier - Order the BIFMA-tested version for regulated markets, or the standard-grade version to reduce cost where BIFMA isn't required by your end customer - same base, two cost paths.
SGS-Verified Test Reports on File - Third-party BIFMA test documentation available for the certified version, useful when your own customers or compliance team need to see verification, not just a claim.
Premium Finish for Higher-End Chair Lines - Fine-polished or chrome finish suited to executive, conference room, and premium task chairs where the base is a visible design element, not a hidden part.
Two Size Options for Different Chair Tiers - R=330mm and R=350mm, so you can match base footprint to your chair's seat size and target price point without redesigning the chair.
Factory-Direct, Not Trading Company - Manufactured in-house in Anji (China's chair manufacturing hub), roughly 3 hours from Shanghai and 1.5 hours from Hangzhou by road - factory visits welcome for buyers doing supplier qualification.
Predictable Bulk Economics - MOQ 500 pcs, up to 2,000 pcs per 20FT container depending on size, with standard 30-day production lead time after deposit.

BIFMA-Certified or Standard Grade - Which Should You Order?
Not every market requires BIFMA certification, and paying for it when your end customer doesn't ask for it just adds cost without adding sales value. The ALB05 is offered in two versions so you can decide:
BIFMA-Certified Version
Recommended if you're selling into the US/North American market, supplying a chair brand with its own compliance requirements, or your end customer explicitly requests certified components. SGS BIFMA test reports are available on request.
Standard Grade Version
Same base structure and finish quality, without the BIFMA testing/certification cost. A common choice for markets without mandatory chair safety certification requirements, or for lower-price-tier chair lines where certification isn't a purchasing factor for your customer.
💡 If you're not sure which tier fits your target market's requirements, tell us where you're shipping and what kind of chairs you're building - we can advise which version makes sense before you place a trial order.
SGS BIFMA Testing Report:
Verified, Not Just Claimed
SGS BIFMA test documentation available for the certified version of this base, covering the standards it was tested against.
We are a factory, not a trading company - production, tooling, and QC happen on our own line in Anji, Zhejiang (China's chair manufacturing hub).
Factory visits are welcome for buyers running supplier qualification or due diligence before committing to volume orders - roughly 3 hours by road from Shanghai Pudong Airport, 1.5 hours from Hangzhou Airport.
If your procurement process requires supplier audits, test report review, or a factory visit before approval, we're set up for that process rather than treating it as an exception.
Matching Base Size to Your Chair Line
R=330mm - Lighter Option
(1.50 KGS), higher container loading (2,000 pcs/20FT), suited to standard task and mid-tier office chairs where cost efficiency matters most.
R=350mm - Larger Footprint
(1.75 KGS), suited to executive and higher-back chairs where a wider base better matches the visual proportions and stability expectations of a premium chair.
💡 If you're developing a new chair model and unsure which size fits your design, share your seat height and target chair category - we can recommend the size that matches both stability needs and finish expectations for that price tier.
Quality Control
Aluminum casting and polishing/chroming process controlled on our own production line.
BIFMA-referenced testing conducted for the certified version, with SGS test reports available for buyer review.
Dimensional consistency checked across both size options (R=330mm / R=350mm) to keep repeat orders matching original spec.
Pre-shipment random sampling (AQL) before container loading.
Since 2004, chair base production has stayed in-house, which is part of why we can offer factory visits and documentation review rather than asking buyers to take quality claims on faith.
Typical Applications
Frequently Asked Questions
Q: Are you a factory or a trading company?
A: We are a factory. Production, tooling, and quality control are handled in-house in Anji, Zhejiang.
Q: Where is your factory located, and can we visit?
A: Anji, known as the hometown of the chair industry in China - about 3 hours by road from Shanghai Pudong Airport, or 1.5 hours from Hangzhou Airport. Factory visits are welcome for buyers doing supplier qualification.
Q: Can your products pass BIFMA testing?
A: Yes - this base is available in a BIFMA-certified version with SGS test reports on file, as well as a standard-grade version for buyers who don't need certification for their target market.
Q: Which version should we order - BIFMA-certified or standard grade?
A: It depends on your target market and end customer requirements. If you're selling into a market or to a brand that requires certified components, choose the certified version. If certification isn't a requirement, the standard-grade version offers the same structure and finish at a lower cost.
Q: What's the difference between the polished and chrome finish?
A: Both are premium finish options for the same base structure - choice typically comes down to matching your chair's overall hardware finish (e.g. chrome to match chrome armrests/frame, polished for a more matte premium look).
Q: What are your payment terms?
A: T/T or L/C at sight, standard for export orders.
Need a Base That Matches Your Market's Compliance Requirements?
