Koas is an office furniture specialist founded in 1984 and listed on the KOSPI in 2005 under the former name Korea OA.
The company produces office furniture under the Millennium and U-Plex lines as well as student desks and chairs, positioning smart-office-concept products incorporating IT technology as its core offering.
It operates a domestic distribution network of roughly 170 dealers alongside export channels covering about 30 countries.
The competitive landscape mixes large brands such as Fursys, Hanssem, Hyundai Livart, Ace Bed, and Zinus with smaller furniture makers, and a recent brand reputation ranking placing Ace Bed, Hanssem, Fursys, Zinus, and Hyundai Livart at the top underscores Koas's relatively weaker brand recognition.
Following a change in controlling shareholder, the company pursued entry into biotech by acquiring a stake in drug developer Novelty Nobility, announcing a plan involving roughly KRW 50 billion in third-party rights issues and convertible bond subscriptions.
The transaction proved turbulent, however, as a contract termination notice from Novelty Nobility in September 2025 derailed the initial capital payment, and subsequent reports indicated a revised agreement transferring a controlling stake to Koas.
Around the same period, the company also made a large purchase of shares in the delisting-bound Ewha Group companies (Ewha Electronics, Etron, and EID), becoming Ewha Electronics' largest shareholder, a process that led to an unfaithful disclosure designation over delayed and inaccurate filings.
Since the ownership change, Roh Byung-gu, formerly head of Solux, has served as co-CEO, jointly overseeing both the core furniture business and the new ventures.
