R&D Team
Brand Story
Zhejiang Rundake KOHO Furniture Co., Ltd. was founded in Anji, China’s renowned hometown of chair manufacturing. Led by a founding team with profound insights into office seating and a persistent commitment to original design, the brand started its journey in a rented factory workshop. Back then, few could foresee that this small startup with merely dozens of staff would grow into an international brand present in 140 countries across the globe over the next decade.
2012 · Origin
Our Brand made its debut at CIFF China Furniture Fair with self-developed original office chairs. This marked the brand’s first official debut to the industry. Rooted in original design, Our Brand drew initial attention and recognition from industry peers for its distinctive interpretation of product form and functionality. The brand positioning was finalized that year: not a follower, but a creator.
2013 · Debut
Our Brand officially stepped into overseas markets, participating in world-class furniture expos including ORGATEC Germany and INDEX Dubai. ORGATEC is the world’s most professional exhibition platform dedicated to office furniture, gathering professional buyers and distributors worldwide; INDEX is the largest and most influential high-end furniture fair across the Middle East. Supported by original Chinese design, Our Brand stepped onto the global competitive stage for office furniture for the first time.
2014 · going Global
Taking the domestic Chinese market as its foundation, Our Brand leveraged it as a springboard to launch targeted global market expansion. In the same year, the brand signed its first overseas distributor and opened an overseas showroom. This marked a critical leap for Our Brand: shifting from simple product exportation to localized brand establishment, transforming from “going global” to “taking root overseas”.
2015 · Localized Rooting
Our Brand continued to expand its global footprint. Boasting original designs and reliable quality, its products won growing recognition from professional overseas buyers. The brand’s production volume in the international office furniture industry climbed steadily, building a solid foundation for its global expansion plan in the years ahead.
2016 · Deep Cultivation
2017 stands as a landmark year for Our Brand. It became the first furniture enterprise in Chinese mainland to receive official certification from Chicago’s design authorities and was invited to showcase at NEOCON USA. As the world’s most influential platform for commercial design, NEOCON granted Our Brand an official Design Award from the global authoritative design community. This award not only serves as a powerful international credential for Our Brand’s products, but also signifies that original Chinese office chair design has secured a central spot on the global stage.
2017 · Glory Milestone
The company’s annual output value surpassed 100 million RMB. That same year, Our Brand brought on designers from Germany, Sweden, Denmark and other countries to join its R&D team, laying groundwork for a brand-new high-end brand. Evolving from a single brand to a multi-brand portfolio, Our Brand embarked on a new phase of brand-oriented operation。
2018 · Rapid Leap
Our Brand officially launched Sitstar, its stylish aesthetic office chair brand (Preview). Focused on designing and manufacturing high-quality trendy furniture, the brand integrates cutting-edge trend elements to craft a laid-back, comfortable lifestyle, delivering distinctive product experiences for young global consumers. The “Sitstar” trademark was officially registered in the same year.
2019 · Breaking New Ground
Our Brand was awarded the title of National High-tech Enterprise. This national-level accreditation serves as authoritative recognition of the company’s comprehensive strength in core technology R&D, independent intellectual property rights, and commercialization of scientific and technological achievements. As we shift from traditional manufacturing to smart manufacturing, Our Brand’s technical edge has become increasingly prominent.
2020 · Official National Certification
Our Brand completed a comprehensive brand upgrade and launched a brand-new logo infused with the design philosophy of “Made in China, Intelligent Manufacturing”. The upgrade covered overall shape, visual identity, font system and brand concept. With refined visual communication, the brand better conveys its corporate values and facilitates more effective brand recognition & communication.
2021 · Full Brand Upgrade
Our Brand was accredited as Zhejiang Provincial High-tech Enterprise R&D Center. Our R&D investment accounts for 10% to 15% of total output value, a remarkably high ratio within the furniture industry. Multiple products have won domestic and international design awards, a testament to industry-wide recognition of Our Brand’s R&D strength. By this year, Our Brand owned more than 70 patents including invention patents, utility model patents and design patents.
2022 · Refined Technology & Design
Groundbreaking construction kicked off for Our Brand’s brand-new smart factory in Anji. The new plant covers a land area of over 200,000 square meters with a construction area of 57,000 square meters. In the same year, Zhejiang Our Brand Intelligent Technology Co., Ltd. was formally registered. This marks Our Brand’s accelerated transformation from a furniture manufacturer to a tech-driven innovative enterprise. Our Brand also received the “High-Growth Model Enterprise” honor certificate issued by the People’s Government of Anji County.
2023 · Groundbreaking for Smart Factory
Our Brand launched Starlook, its brand-new high-end leather office chair brand. Integrating elegant Italian aesthetic lines, exquisite craftsmanship and modern minimalist design concepts, the brand targets the mid-to-high-end leather business chair market. In the same year, Our Brand’s brand exhibition hall inside the new smart factory in Anji officially opened. Covering a construction area of over 50,000 square meters, the headquarters complex integrates modern production workshops, corporate office buildings and joint exhibition halls for its three major brands.
2024 · Brand Renewal
The brand-new injection molding production lines were officially put into operation, forming the prototype of a fully automated dark factory. The annual output value surged to 320 million RMB. As of 2025, Our Brand held a total of 83 patents. Its original-designed products are sold to more than 140 countries and regions across North America, Europe, South America, the Middle East and Southeast Asia.
2025 · Smart Manufacturing
Starting as a startup operating in a rented factory in Anji back in 2012, Our Brand has grown into an international brand with an annual output value of hundreds of millions and products distributed across 140 countries worldwide by 2025. Over more than a decade, Our Brand has written a Chinese brand story rooted in original design, smart manufacturing and a global vision. It stands as a microcosm of Anji’s chair industry transforming from a “World Factory” to a “World Brand”, and also a vivid example of China’s furniture industry going global powered by original design and advanced technology. Sun Mingliang, Chairman of Our Brand, stated publicly that within the next five years, the brand plans to expand its customer coverage to every country in the world, building Our Brand into an influential global brand.
