Yisen Office Chair (Related to IDÅSEN Chair)
There is no definitive information indicating the existence of a 'Yisen Office Chair', but there is an introduction to the 'IDÅSEN Chair'. It is uncertain whether the 'IDÅSEN Chair' belongs to the 'Yisen' brand. Here is an introduction to the features of the 'IDÅSEN Chair':

Backrest Adjustment Function
The backrest of the 'IDÅSEN Chair' has excellent adjustability, allowing for five different height settings. This multi-height adjustment design can meet the needs of different users in various usage scenarios. For example, when a user needs to focus on office work for an extended period, the backrest can be adjusted to a relatively high position to provide more comprehensive support for the back, reducing fatigue in the back muscles. When engaging in more relaxed activities such as conversations or reading, the backrest can be lowered to create a more comfortable sitting posture. Additionally, the chair comes with a built-in lumbar support that conforms to the natural curve of the human waist, providing effective support to the waist, helping to maintain proper sitting posture, and preventing the occurrence of waist diseases, making it especially suitable for office workers who sit for long periods.
Headrest Adjustment Function
The headrest of the chair features height adjustability and forward-and-backward movement capabilities. The height adjustability allows users of different heights to find a suitable headrest position, ensuring that the head receives good support during rest or work. The forward-and-backward movement function further enhances flexibility in use. Users can adjust the distance between the headrest and the head according to their sitting posture and needs, whether they want a closer fit for better support or a certain distance for a wider field of view.
Armrest Adjustment Function
The armrests of the 'IDÅSEN Chair' are designed with great user-friendliness, allowing for both height and horizontal angle adjustments. The height adjustment enables the armrests to adapt to desks of different heights, keeping the arms in a natural and comfortable position and reducing pressure on the arms and shoulders. The horizontal angle adjustment further meets the needs of users in various activities. For example, during gaming, the armrests can move back and forth with the arm movements, providing players with a more flexible operating space and enhancing the gaming experience.
Safe Caster Function
The chair's safe casters are equipped with a pressure-sensitive braking mechanism. When a user sits down, the casters automatically brake to prevent the chair from sliding, ensuring safety during use. When the user stands up, the braking mechanism is released, allowing the chair to move freely. Moreover, the casters are covered with rubber, which enables smooth sliding on various types of floors without causing damage, making them both practical and environmentally friendly.
