Sheng Ang Office Chair

The "Sheng Ang Office Chair" mainly refers to the products represented by the "Antina/Office Chair" under Hangzhou Sheng Ang Furniture Co., Ltd., with the following core information:

1. Brand and Trademark Background

"Sheng Ang" is a registered trademark of Hangzhou Sheng Ang Furniture Co., Ltd. (Application/Registration No. 19264339), classified under International Class 20 for furniture, covering office furniture, sofas, and other products. Founded in 2014, the company's business scope includes furniture sales and after-sales services, with a brand positioning targeting the mid-to-high-end office furniture market.

2. Materials and Craftsmanship

1. Main Materials: The chair body combines leather with molded foam. The leather used for the backrest and seat cushion is imported from Europe, specifically from小黄牛皮 (yellow calfskin) at 36° north latitude, known for its natural texture and breathability. The molded foam is processed through high-density foaming technology, providing long-lasting support and resistance to deformation.
2. Armrest Design: The diamond-shaped armrests feature a metal frame made from the same material as luxury car cylinders, covered with a genuine leather soft-pack finish that balances aesthetics and durability. Their fatigue life is 100 times longer than that of ordinary armrests, with a 20% increase in surface hardness and a 20% enhancement in wear and corrosion resistance.

3. Functional and Design Features

1. Ergonomic Structure:
   • The backrest measures 790mm in height and 380mm in width, with a slim design of only 25mm, conforming to the natural curve of the spine and helping to prevent spinal sub-health issues caused by prolonged sitting.
   • The 3D-molded seat cushion is divided into three zones: the tail shaping zone (135N high-density cotton) provides reinforced support; the middle protection zone (85N medium-firm cotton) distributes pressure evenly; and the front pressure-relief zone (60N soft cotton + 15° slope design) reduces leg compression.
2. Design Team and Philosophy: Designed by the renowned German design team Form And Branch, the chair integrates humanistic aesthetics, healthy office concepts, and futuristic technology elements, featuring a minimalist and modern appearance that suits various office environments.
