Office Chair - US Haman (Translation Note: No Such Model)

The US office furniture manufacturer Herman Miller has never launched an office chair named 'haman', but its Embody and AERON are two classic ergonomic products. Here are the details:

Embody Office Chair: Innovative Design and Functional Integration

The Embody is a high-end ergonomic office chair launched by Herman Miller in 2008, primarily designed by William Stumpf and Jeff Weber. Its core innovation lies in the Dynamic Pixel Matrix Technology: the backrest is composed of hundreds of independent support points that automatically adjust the support angle according to the user's sitting posture, dispersing spinal pressure. Additionally, the BackFit Adjustment Mechanism allows users to control the backrest curve via a knob, ensuring precise lumbar support at all times. The seat supports depth adjustment (up to 6 cm extension) to accommodate users with different leg lengths; the height adjustment range is 15 cm, covering the height requirements of most office desks; the armrests can be adjusted up and down, forward and backward, and at angles to meet the needs of various scenarios such as typing and reading. This product has won the Red Dot Design Award in Germany and the Industrial Design Excellence Award in the US, and was named one of the 'Best Inventions of 2008' by Time magazine.

AERON Office Chair: Classic Status and Continuous Iteration

The AERON is a landmark product launched by Herman Miller in 1994, renowned as the 'benchmark for ergonomic chairs'. Its design breakthrough lies in the Sacral Support Technology: through the 8Z Pellicle suspended mesh and the PostureFit SL adjustment system, it directly supports the sacral region, reducing lumbar fatigue caused by prolonged sitting. The backrest comes in three sizes—large, medium, and small—to accommodate users with different body types; the front edge of the seat adopts a waterfall design to prevent impaired blood circulation in the legs. In 2016, Herman Miller introduced the AERON Remastered version, upgrading the 8Z Pellicle mesh material and the PostureFit SL adjustment system, and adding a graphite frame option. This product has consistently ranked among the top sellers in the global high-end office chair market and is permanently collected by the Museum of Modern Art (MoMA) in New York.
