Upholstery
Eco-friendly microfiber leather-comfortable to the touch, easy to maintain, wear-resistant, durable, and excellent value for money.
Headrest
Height-adjustable padded headrest with a 70mm adjustment range to accommodate users of different heights. Ergonomically designed with a scientific curve for a comfortable fit that relieves shoulder and neck tension.
Padding
Armrests feature high-density molded polyurethane foam with up to 95% resilience; foam density is 50 kg/m³. The seat and backrest use virgin polyurethane foam with a density of ≥40 kg/m³ and resilience of ≥35%. The material is eco-friendly, non-toxic, and odorless, providing comfortable support that retains its shape and does not sag even with long-term use.
Base Material
The integrated seat and backrest are injection-molded from food-grade virgin polypropylene (PP+GF) reinforced with glass fiber. Eco-friendly, non-toxic, and odorless; high strength, resistant to deformation, excellent toughness, comfortable rebound, and superior seating comfort.
Armrests
Fully wrapped armrests integrated with the backrest provide comfortable support when reclining and are easy to use.
Lumbar Support
Height-adjustable padded lumbar support with a 60mm adjustment range. Designed with a pronounced curve to match the natural curvature of the spine, it provides snug support and alleviates muscle soreness from prolonged sitting.
Gas Lift
Three-stage anti-burst gas lift with a 2mm-thick inner core and 1.5mm-thick outer tube. Filled with nitrogen at 6-8 MPa, it offers an 85mm lifting stroke.
Mechanism
A wide-angle, multi-functional, cable-controlled mechanism with a 18-degree recline range and 4-position locking. The backrest recline function has passed the 120,000-cycle pull-back test required by the BIFMA X5.1-2017 standard.

FAQs
1
Why does the Uno A663 series use a plastic back frame?
The Uno A663 series features a back frame made of high-strength, high-toughness PP (polypropylene) through a single-piece injection molding process. Compared to traditional wooden frames, it not only offers smoother lines and more precise contours, but more importantly, it serves a triple function: decorative, supportive, and structural. While ensuring structural integrity, this design optimizes overall costs by 30%. Every back frame is dimensionally consistent and of stable quality-something that cannot be achieved with wooden frame craftsmanship.
2
What is the adjustment range for the headrest and lumbar support?
The A663 series features independent 70 mm height adjustment for the headrest and 60 mm height adjustment for lumbar support. This means users ranging from 158 cm to 188 cm in height can find the perfect support point for themselves. The headrest is soft and cushioned for comfort, while the lumbar support is firm and supportive. Adjustments require no tools and can be made with just one hand.
3
What is the five-zone foam? How does it feel when sitting?
We divide the seat into five zones: head, back, lumbar, seat, and armrests. Each zone uses foam layers of varying densities (up to 55 kg/m³) and thicknesses based on its specific load-bearing characteristics. The lumbar zone is firm, providing strong support; the seat cushion is highly resilient, maintaining its shape even after prolonged use; and the backrest is soft, offering a comfortable, enveloping feel. This zoned design ensures even pressure distribution, preventing localized fatigue.
4
Why does every Uno A663 chair undergo a metal detector check before leaving the factory?
Hidden inside the chair's upholstery are multiple metal fasteners used to secure the fabric to the back frame. Once installed, these fasteners are invisible and imperceptible to the touch, but if any are missing, the fabric will become loose over time. We use a metal detector to scan every finished chair individually, ensuring all fasteners are in place-this chair that must pass "security screening" is our commitment to durability.
5
What tests has the Uno A663 series passed?
We test according to the BIFMA X5.1 and EN 1335 international standards, while also enforcing stricter internal standards: 1,300 kg static load on the chair legs (industry standard: 1,136 kg), 136 kg load on the casters for 150 km of operation (industry standard: 102 kg for 106 km), and three impact tests on the base (industry standard: 1 test). This is the source of our confidence in offering a 10-year structural warranty.
6
How precise is the stitching?
We use automated cutting machines to cut leather with millimeter-level precision, and the sewing process is overseen by experienced master craftsmen, with stitching deviations strictly controlled within 0.5 mm. Each piece of leather is marked with a "straight edge" indicator to ensure precise alignment during assembly. It is these details that define the line between "perfection" and "cheapness."
7
What is the difference between the Uno A663 and the Uno A663J?
The Uno A663J features a hidden, padded footrest in addition to the standard Uno A663. During work, the footrest is tucked away under the seat; when resting, it can be gently pulled out to support the calves. Combined with the 27° recline angle, it is ideal for scenarios requiring a midday nap or extended relaxation. All other functions and configurations are identical.
8
In what types of spaces is the Uno A663 series suitable?
In terms of design, the Uno A663 series features an elegant and dignified aesthetic with a distinct business-oriented style, allowing it to blend seamlessly into executive offices, executive suites, and high-end conference rooms. At the same time, its comfortable seating and adjustable features also make it an excellent choice for home offices. The AUno A663 model is better suited for meeting spaces.
9
Can the upholstery be customized?
Yes. We offer two primary upholstery options: eco-friendly microfiber and top-grain leather, with a wide range of color options available (Pantone color codes accepted). The softness, chair castor, brand logo and packaging can also be customized. Minimum order quantities are negotiable.
10
How long is the warranty? What components does it cover?
The Uno A663 series comes with a 10-year structural warranty covering core structural components such as the back frame, base, gas lift, and five-star base (under normal use). We are confident in offering a 10-year warranty because we have set standards for materials, craftsmanship, and testing that far exceed industry norms.
