Popular B office chairs include the Sihoo B100Pro and the Ergotune B Eagle X, each with its own unique features.

Sihoo B100Pro

• Lumbar Support Design: Its lumbar support is positioned relatively low, making it more suitable for users who prioritize sacral support. The lumbar support is equipped with springs at the back, allowing for adaptive front-to-back adjustment. However, it lacks height adjustment functionality, and overall, the lumbar support is not particularly strong.
• Armrest Design: The connecting material is nylon, and the contact surface is soft leather with a thin layer of sponge, though the feel is somewhat stiff. The armrests can be adjusted forward and backward and can rotate 360 degrees, meeting users' needs in various usage scenarios.
• Other Features: It features a "dynamic support" design where the lumbar pillow automatically conforms to the user's sitting posture, providing a more comfortable support experience. The headrest can be adjusted up, down, forward, and backward, allowing users to find the most suitable position. The seat cushion is made of mesh fabric, which is breathable and soft, making it comfortable even after prolonged sitting. It is highly adjustable, with seat height, armrest height, and backrest tilt angle all adjustable to accommodate users of different heights and sitting habits. The wheels are smooth and quiet, leaving no marks on wooden floors and causing no damage to the surface.
• User Reviews: It has a 95% positive rating on JD.com, with buyer impressions including comfort, easy installation, breathable mesh, easy operation, and good stability, indicating that this chair has a good reputation among users.

Ergotune B Eagle X

• Adjustability Features: The headrest is a 2D headrest that supports height adjustment and a wide range of pillow surface rotation angles. Its shape is inverted triangular, suitable for users with wider shoulders and necks. The backrest has a height adjustment function, and the headrest can move up and down with it, increasing the height range and meeting the needs of users of different heights. The lumbar pillow can be adjusted for support intensity by changing the front-to-back position of the support bars, allowing users to personalize the adjustment based on their own lumbar sensations.
• Material Quality: The mesh fabric used is Q3.5 American mesh, which is of good quality and provides a comfortable sitting experience and good breathability. The chassis is a unique eight-axis linkage chassis, offering a smooth recline experience and allowing users to relax more during rest.
