Office Chair Review in Japan
The office chair review in Japan covers multiple products and testing standards. Here is a detailed introduction:
Popular Brands and Products
- ITOKI Office Chair: It has a low-profile appearance and rich functions, including height adjustment, tilt locking, and seat sliding. Its armrests are designed in 4D, allowing for height, forward-backward adjustment, and rotation. The materials used are very particular. It performs well when leaning back. The mesh fabric has strong longitudinal elasticity and weak lateral elasticity. The sponge seat feels relatively hard. There is a hidden lumbar support at the back, and the adjustment changes are obvious.
- Okamura (Okamura) Ergonomic Chair:
- portone: As an entry-level product, it uses a high-density foam cushion, which has good load-bearing capacity and is suitable for people with a relatively large weight. The chair back has an independently adjustable lumbar support with an adjustable support angle up and down. The 3D armrests support vertical, forward-backward, and left-right rotation adjustments, and also have a seat depth adjustment function.
- Abilis Series: It offers high cost-effectiveness. The 3D floating lumbar support can automatically adapt to different body types. When leaning back, the lumbar support intelligently moves forward by 2cm. The butterfly-shaped cushion is made of high-elasticity mesh fabric, and the edges are raised by 15ยฐ. It is suitable for users with a height of 155cm - 190cm.
- Sagesse Series: It features a no-installation design. The gravity-sensing chassis can automatically adjust the back-leaning resistance according to the user's weight. The shoulder-neck linkage system enables the headrest to be adjusted in 7 segments synchronously when the chair back is tilted. During a 135ยฐ large-angle back lean for a lunch break, the cervical spine can maintain a natural curve.
- Sylphy Series: It is suitable for both gaming and office use. The chair back has more than 2000 elastic support points built in, with zero-delay response. The 4D armrests can move 8cm left and right, slide 5cm forward and backward, have a soft rubber surface material, and a 15ยฐ inward rotation design.

Testing Standards
JIS S 1032 Japanese Office Chair Testing Standard: JIS S 1032:2016 is a specialized standard for office chairs formulated by Japan to meet the needs of modern office environments. It aims to ensure the safety and durability of office chair products and promote the standardized development of the office furniture industry. This standard is applicable to office chairs, including swivel chairs, non-swivel chairs, folding chairs, and stools. The testing items cover stability tests, such as front stability, side stability of armless chairs, and rear stability; static strength and durability tests, including seat surface static strength tests and backrest static strength tests; and impact resistance tests, such as seat surface impact resistance tests and backrest impact resistance tests.
