Sihoo Ergonomic Office Chair M18
M18-M148
Community verdict
The Sihoo M18 is widely praised as an accessible budget entry into ergonomic office seating, delivering solid build quality and reliable back support for daily work. Most buyers highlight its straightforward assembly, breathable mesh backrest, and strong value proposition compared to premium competitors. However, reviewers frequently caution that the lumbar support can feel overly stiff, the seat cushion is quite firm, and the chair may feel restrictive for taller or heavier users.

4 quotesDirect organic buyer opinions about Sihoo Ergonomic Office Chair M18, filtered for spam and ads.
The first surprise was nothing more than opening the box and seeing the quality of the product piece by piece: a solid and balanced base
It really is the best budget chair on the market and has been for a few years.
The armrests at their lowest stand very tall... They're hard and uncomfortable in a way that is actually seriously painful for my elbows
I'm 6'2" (70kg) and returned my M18 last week - just couldn't get comfortable in it. The backrest frame dug into my back
