What Makes This Counter Height Adjustable Stool Stand Out?

The YB-678-2 is built around true ergonomic principles. The pneumatic gas lift enables an easy, tool-free height adjustment, allowing users – a toddler at a kitchen island or an adult at a standing workstation – to set the seat-to-surface disparity to the ideal range of 10-12 inches. It lowers tension on the lower back, eliminates dangling legs and maintains natural posture while in use for long periods.

The 3.8 cm high density sponge seat does not deform under repeated static loads and retains its shape. The 0.8 mm half-PU upholstery is simple to wipe clean and can withstand regular wear. Available in bespoke colours and materials to complement your area.

All supported by a heavy-duty solid base. Base diameter minimises tip-over risk – an important safety metric in hospitality and commercial environments – designed to keep the center of gravity low at top height extension.

Material & Construction Details

Every component in this Counter Height Adjustable Stool is selected for longevity and structural performance.

Seat shell: 1.0–1.2 cm plywood — rigid, stable, and lightweight
Padding: 3.8 cm high-density foam — firm yet comfortable
Upholstery: 0.8 mm half-PU — durable, easy-clean surface
Stitching: Back-and-front double needle thread — seams resist tension fatigue under daily use
Hardware: 6×14 mm screws (4 pcs) — secure, tight-fitting assembly

The double-needle stitching detail deserves attention. In contract-grade seating, seam failure under tension is a documented quality risk. The back-front double stitch method reinforces the most stress-prone areas of the upholstery, extending the lifespan of the cover significantly.

Assembly is straightforward. All components are pre-packaged and labeled, so setup requires no special tools or technical knowledge.

Quality Control & Certification

Anji Yibo's quality assurance is more than eye examination. Before delivery, every unit gets checked for structural and mechanical integrity.

The integrity of the gas lift is tested to prevent the usual "sinking" problem caused by a failure of the nitrogen seal. The pneumatic cylinder is subjected to vertical cycling and sudden-impact tests for durability testing to ensure constant height-lock operation.

Base load testing delivers localised pressure to the edge of the seat – replicating real world, off center weight distribution – to ensure the base does not distort or separate. Stability at maximum height extension is checked under an off-centre load in accordance with the stability principles of EN 1022.

Upholstery seam testing tests double-needle stitching for tensile fatigue to ensure that the cover won't tear prematurely under high-use conditions.

Certifications cover REACH (chemical safety), EN 12520 (structural strength and durability of home seating), BS 5852 (fire resistance) and TUV verification – giving the paperwork trail that procurement teams and importers usually need.

why choose us

Applications: Where This Stool Performs Best

The height-adjustable design of this Counter Height Adjustable Stool makes it a flexible asset across multiple settings.

Kitchen islands and home dining: Families with mixed ages benefit most from adjustable seating. Children can be raised to a safe eating height; adults can lower the seat to fit comfortably under the counter overhang. One stool SKU serves the whole household.

Bar counters and bistro environments: In hospitality settings, the ability to reposition seating between dining counters and high-top surfaces without buying multiple furniture types reduces inventory costs meaningfully. The easy-clean PU surface supports fast turnover and hygiene management.

Agile office and co-working spaces: At standing desks or collaborative high-top tables, employees can transition between standing and perched sitting without losing focus. The swivel function allows quick repositioning without scraping the floor.

Customization & B2B Supply Options

You can tailor the YB-678-2 to your market's specific needs. Customizable elements include:

Upholstery fabric — standard half-PU or upgrade to weatherproof, shockproof, and impact-resistant fabric
Color options — match your brand palette or interior design concept
Base style — choose the base configuration that suits your floor type and aesthetic

For bulk orders, the 5-layer reinforced corrugated carton (200 lbs rated) with a 2-pcs/carton packing configuration is optimized for container loading efficiency, reducing per-unit freight cost. The compact 0.124 CBM per carton means more units per container compared to less efficiently packed alternatives.

MOQ starts at 100 pieces per model. Production lead time is 40–45 days, with sea freight approximately 30 days depending on destination port.

FAQ

Q: What is the minimum order quantity?

A: The MOQ is 100 pieces per model.

Q: Why does an adjustable stool sometimes sink over time?

A: This is caused by nitrogen seal failure in the gas lift cylinder. Our units use quality-grade cylinders tested for seal integrity to minimize this risk.

Q: How do I tell a counter height stool from a bar stool?

A: A true product typically bottoms out at around 24 inches (61 cm), fitting 36-inch counters. If the minimum height starts at 28 inches or higher, it functions only as a bar stool.

Q: Can I customize fabric and color?

A: Yes. We support custom fabrics, upholstery upgrades, base styles, and colors to match your requirements.

Q: Do you offer volume pricing?

A: Full container orders receive more competitive pricing. Send your inquiry to yb@ajyibo.com for a detailed quote.

Q: What is the warranty period?

A: All units come with a one-year warranty.
