Black and White Tone Ergonomic Chair E301: This model stands out with its multi-directional adjustment capabilities as its core advantage. It supports basic adjustments such as seat cushion height, backrest recline, footrest extension, and seat depth, catering to the seating size needs of users of different heights and body types. Its armrest system offers four-way adjustment including height, forward-backward, left-right, and rotation. The lumbar support features height adjustment and follows the contour of the waist dynamically, while the headrest provides height, forward-backward, and rotation adjustments to cover neck support needs. The multi-dimensional adjustment design makes it suitable for various scenarios such as office work, meetings, and lunch breaks, especially for users who need to frequently adjust their sitting posture to alleviate fatigue.

Black and White Tone P1 Ergonomic Office Chair: This model emphasizes safety and comfort. It utilizes a Class IV BIFMA-standard gas lift that has passed international safety certifications, ensuring stability and durability during height adjustments. The adjustable lumbar support has undergone 120,000 backrest recline tests, demonstrating reliable support strength. Paired with a 145° large-angle reclining function, it meets the needs for short breaks. Its design focuses on prolonged office scenarios, dispersing prolonged sitting pressure through the collaborative support of the lumbar support and backrest, making it suitable for professionals such as programmers and designers who need to maintain a sitting posture for extended periods.

Black and White Tone T8Max Smart Ergonomic Chair: As a premium model, this product features dynamic fitting technology and integrates 20 adjustment functions, covering full-dimensional adjustments such as seat height, depth, tilt, armrest angle, lumbar support position, and headrest height. Its smart control architecture automatically adjusts support strength based on user sitting posture data. For example, when the user leans forward to work, the lumbar support actively pushes forward to provide support; when reclining for rest, the backrest and headrest adjust their angles simultaneously to form a continuous support surface. This model offers a systematic solution to the problem of lower back strain from prolonged sitting, suitable for users with high demands on chair functionality.
