SMOOTH HEIGHT ADJUSTMENT: 8.5" stroke piston gives a 19.5"–28" height range, 2" outer tube and 1-⅛" tapered stem. Whisper-quiet lift plus 360° swivel makes it perfect for bar stools, kitchen islands, workbenches or vanity tables.

SAFETY CERTIFIED & DURABLE: Validated by BIFMA, SGS and TÜV Rheinland, the cylinder uses premium steel with an anti-burst ring that resists rust, leaks and cracks. Cycle-tested for 50,000+ adjustments to give years of reliable everyday use.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $9 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for MASTERY MART products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
