Office Chair Recommendation by Luo Yonghao
The office chairs recommended by Luo Yonghao are the Heilao E3Pro ergonomic chair and the Sihoo C300 second-generation Pro ergonomic chair. He has also explicitly criticized the Humanscale Freedom chair and does not recommend purchasing it.
Recommended Model: Heilao E3Pro Ergonomic Chair
The core advantage of this chair lies in its 4D่ๅจ (4D linked) armrest design, which supports 90-degree folding and reclining linkage functions, adapting to different sitting postures. The lumbar support system can be adjusted independently up and down, and combined with breathable mesh fabric, it helps relieve pressure from prolonged sitting. Additionally, it is equipped with a 2D headrest, a 135-degree three-position locking recline function, and a 4-level gas lift, ensuring both safety and comfort.
Notable details to consider include: the initial recline angle of the backrest is relatively large, which may affect ease of getting up; the mesh fabric of the lumbar support is relatively soft, and heavier users may touch the plastic frame during use; the armrests only support front-back, left-right, and rotational adjustments, without independent height adjustment, limiting adaptability for users with significant height differences.
Recommended Model: Sihoo C300 Second-Generation Pro Ergonomic Chair
This chair stands out with its multi-dimensional adjustment functions: the headrest supports front-back and up-down adjustments, the backrest can be raised and lowered, the seat depth is adjustable, the armrests offer infinite adjustment, and the lumbar support uses dynamic tracking technology to automatically conform to the lumbar curve based on sitting posture. Additionally, the brand provides on-site installation services (by appointment), suitable for users with lower DIY skills.
Not Recommended: Humanscale Freedom Chair
Luo Yonghao publicly criticized this chair at the 2025 "Tech Spring Festival Gala," calling it "very poor" and pointing out that despite its high price of 20,000 yuan, it has significant flaws. Although some users (such as Crocodile Thirteen) report comfort, Luo explicitly does not recommend it, believing its cost-effectiveness does not match the actual experience.
Purchase Recommendations: If you prioritize cost-effectiveness and multi-functional adjustments, consider the Sihoo C300 second-generation Pro first; if you prefer breathable mesh fabric and independent lumbar support adjustment, the Heilao E3Pro is a better choice; due to price and reputation controversies, the Humanscale Freedom chair is advised with caution.
