Office Chair Recommendation by Luo Yonghao
Luo Yonghao has recommended two ergonomic office chairs, the Sihoo C300 Second Generation Pro and the Hebadiao E3 Pro, while publicly criticizing the Humanscale Freedom office chair as 'very poor'. Here is a detailed breakdown of the information:

Recommended Products: Sihoo C300 Second Generation Pro and Hebadiao E3 Pro
Luo Yonghao has explicitly recommended these two ergonomic office chairs in public appearances or promotional collaborations. The Sihoo C300 Second Generation Pro focuses on multi-dimensional adjustability as its key selling point, featuring adjustable headrests, lumbar supports, and armrests to accommodate users of different body types. Its mesh material combines breathability with support, making it suitable for long hours of office work. The Hebadiao E3 Pro, on the other hand, emphasizes dynamic back-following design, using an elastic lumbar support to automatically conform to the user's back curve, reducing fatigue from prolonged sitting. It also comes with 4D armrests and a reclining backrest to meet diverse needs such asๅไผ (noon breaks). Both products are positioned in the mid-to-high-end market, with price ranges between 2000-4000 yuan, and their cost-effectiveness has been recognized by Luo Yonghao.
Criticized Product: Humanscale Freedom Office Chair
Luo Yonghao has publicly evaluated the Humanscale Freedom office chair as 'very poor,' despite its high price tag of 20,000 yuan. His main criticisms focus on design flaws: the Freedom chair employs a self-weight sensing recline mechanism, which automatically adjusts the recline force based on the user's weight. However, this design makes it difficult for lighter individuals to trigger the recline function, while heavier users may experience excessive recline and lose balance. Additionally, the chair's fixed headrest cannot be adjusted for height or angle, making it unfriendly to users with significant height differences. Luo Yonghao believes that, as a high-end product, the Freedom chair fails to meet basic functional requirements and offers extremely poor value for money.
Purchase Recommendations
If following Luo Yonghao's recommendations, priority should be given to the Sihoo C300 Second Generation Pro or the Hebadiao E3 Pro, both of which offer balanced performance in terms of adjustability and comfort, suitable for most office scenarios. If the budget allows and an international brand is preferred, careful evaluation of the Humanscale Freedom chair's suitability is necessary, especially considering one's own weight and sitting habits to avoid design flaws affecting the user experience.
