SIHOO was founded in 2011 in Shenzhen, Guangdong Province, China, as a furniture brand focused specifically on ergonomic seating: office chairs, gaming chairs, children's study chairs, and related furniture designed around healthy sitting posture. Manufacturing runs out of a production base in Foshan, in the same Guangdong region, reported at over 100,000 square metres with a workforce of several hundred staff. The company also operates its own in-house ergonomics R&D institute, staffed by 100+ engineers and designers, plus a dedicated testing centre reported at roughly 10,000 square feet, where every chair is put through structural strength, armrest durability, and backrest stress testing before release.
From that base, SIHOO grew into a genuinely global ergonomic furniture brand: SIHOO now ships to 85+ countries, sells an estimated 2.6 million-plus chairs worldwide every year, and has been featured in more than 2,000 media outlets internationally. Over 513,000 customers worldwide have left product reviews, on top of Fortune 500 companies among its business customers.
