By unveiling this chair, Keyhan has revolutionized the office chair production landscape.
The use of high-quality polyamide parts and distinct hollow filling cushions in this chair series represents a compelling fusion of ergonomics and engineering principles.
This chair can be customized with different features based on your individual needs and preferences.
The seat handle can be either a fixed handle with an integrated cover or an adjustable movable handle. It is worth mentioning that the adjustable handle provides height adjustment, the ability to change the distance of the pad from the back of the seat (in both forward and backward directions), and lateral adjustments, which is why it is known as a 3D handle.
This chair features two types of tilt and synchronous mechanisms. These mechanisms are mechanical parts that adjust the angle of the backrest in response to leaning force. The operational differences between the Tilt and Synchron mechanisms are essential to understand.
The tilt mechanism operates with a constant angle between the backrest and seat. When the mechanism is locked, the backrest is immobilized; conversely, when it is unlocked and force is applied, both the backrest and seat move together at a stable angle.
The synchronous mechanism provides a unique feature where the angles of the backrest and seat operate independently. As a result, the seat remains in a fixed position, while the backrest can be adjusted by exerting force. Users can secure the backrest at various angles according to their preference. Additionally, by unlocking the mechanism, users can lean back, enabling movement of the backrest, which effectively helps to reduce fatigue during extended sitting sessions.
Moreover, the seat base is available in options of nylon or steel.
