FAQs
1
What is the fabric of this Uno A663J? Is it easy to take care of?
The Uno A663J 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
Can the headrest and lumbar support be adjusted? What is the adjustment range?
Both the headrest and lumbar support can be adjusted vertically by 70 mm. 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 about the sponge filling of the Uno A663J? Will it collapse after sitting for a long time?
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
What are the materials of the Uno A663J back and seat? Is it safe and environmentally friendly?
Hidden inside the Uno A663J'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 Uno A663J individually, ensuring all fasteners are in place - this Uno A663J that must pass "security screening" is our commitment to durability.
5
What is the design of the armrest? Is it easy to use when leaning back?
The integral wrapped three-dimensional soft bag armrest is connected with the backrest, which is comfortable to support when leaning back and more stable and convenient to use.

Is the gas lift safe? How much is the lifting stroke?

7
Can the backrest recline? Can you lock it? What is the angle?
It is equipped with a large-angle multifunctional mechanism with a maximum tilt of 27, which can be locked at any angle in the tilt range and passed 120,000 pull-back tests.
8
Is there a lunch break function? Is the leg rest easy to use?
It is equipped with a hidden leg rest that can be stored in soft bags, which takes up no space and has a beautiful appearance. You can take a lunch break when you pull it out, and it will not affect your office when you put it away.
