Why not reconsider your "sitting environment" for your new life?

Many people buy new desks and lighting when starting a new life, but perhaps those who reconsider their "chair" are still a minority. However, the average sitting time for Japanese people is 8.2 hours a day (Ministry of Health, Labour and Welfare survey), and for teleworkers alone, it reaches 9.1 hours. The self-reported rate of lower back pain among teleworkers is 63.5% (Remote Work Association survey). The start of a new life is the chance to refresh your "sitting environment."


【Introduction of Featured Products】



【B Series】A new generation chair that changes posture from the sacrum

The newly released B Series this year is equipped with SIHOO's independently developed "Composite Sacral Support." By precisely supporting the "sacrum," which is the foundation of the spine, the pelvis naturally stabilizes, and the spine's natural S-curve is maintained without strain. Please experience the feeling of improved posture just by sitting.



SIHOO B100 Pro

Regular Price: 31,999 yen → Sale Price: 22,799 yen Check it out at the official Amazon store: https://www.amazon.co.jp/dp/B0GFW28MGG

This model retains the B100's sacral support while further enhancing the adjustability of the armrests and headrest. With 4D linked armrests (70° up/down, 4.5cm front/back, 360° left/right) and a 3D wide-angle headrest (10cm up/down + two-axis angles of 20°/45°), you can pursue a "fit that's just for you."


【M Series】Even for your first ergonomic chair. Authentic comfort at an affordable price.

While firmly incorporating the basic ergonomic features with an independent lumbar support and 3D flip-up armrests, the high-density cushion and highly breathable mesh material comfortably support daily desk work. It is supported by many as "ideal for a first ergonomic chair," and you can choose from a wide lineup to suit your budget and preferences.
