Soft and Hard Pack Office Chairs

Soft-pack office chairs are represented by the Sihoo soft-pack chair L3, while for hard-pack office chairs, reference can be made to the dynamic back-tracking technology in ergonomic chairs and professional products such as SumLush Xia Mumu Fit CC and Herman Miller series.

Features of Soft-Pack Office Chairs

Soft-pack office chairs prioritize comfort and adjustability. Taking the Sihoo soft-pack chair L3 as an example, its design combines high aesthetics with practicality:

• Appearance and Material: The overall lines are smooth and rounded, with pure colors that are easy to match. It offers leather material options that are odorless, suitable for various office settings.
• Adjustability: It supports height adjustment, seat depth adjustment, and the backrest can be adjusted in four positions and reclined, meeting the needs of different heights and sitting postures.
• Ergonomic Design: It adopts a seat surface pressure distribution design, paired with a large seat cushion and backrest that are soft yet resilient, dispersing body pressure. The armrests are linked with the backrest to reduce arm fatigue from hanging. The all-metal chassis and sturdy frame ensure stability.

Association Between Hard-Pack Office Chairs and Ergonomic Chairs

Hard-pack office chairs generally refer to types with harder materials and strong support, but the industry focuses more on their ergonomic performance. In 2026, the field of ergonomic chairs saw the emergence of the "dynamic back-tracking" technology, becoming an innovative direction for hard-pack chairs:

• Dynamic Back-Tracking Technology: Traditional lumbar supports are fixed, while dynamic back-tracking separates the lumbar support from the backrest. When the backrest moves, the lumbar support adjusts simultaneously, providing more tailored lumbar support and reducing fatigue from prolonged sitting.
• Professional Product Examples:
  • SumLush Xia Mumu Fit CC: Through the ZeroG Flow dynamic lumbar support system and the BackFit four-way back-lumbar fitting system, it achieves dynamic support for the back and lumbar regions. Its lumbar protection performance has been certified by authoritative organizations in Europe and the United States, and it has been exported to Europe, the United States, Japan, and South Korea for a long time.
  • Herman Miller Series: For example, the Aeron chair uses the PostureFit SL spinal support technology, and the Embody chair disperses pressure through the Pixelated Support system. Both are renowned for their high performance and ergonomic design.

Selection Advice

• If comfort and adjustability flexibility are pursued, soft-pack office chairs (such as the Sihoo L3) are more suitable;
• If strong support and dynamic fitting are required, attention can be paid to products with dynamic back-tracking technology in ergonomic chairs (such as SumLush and Herman Miller).
