EC300 vs EC200: Which one actually fits your need? (5 testers wanted)
USA. Southern CA. 6’2 200 Haven’t found my preference for lumbar support yet but trying to. Have the 200 in my Amazon cart currently and saw this. Hoping this can happen for me because I bought a SIHOO M18 chair and I feel too big for it. Feels like it needs a seat depth adjustment and the head rest

Need an office chair for my home office
Can't speak for the others, but I had the Sihoo M18 for nearly 4 years. It was nice at first, and I bought it based on good reviews. After a year or so, the seat started to get harder and the lumbar became more uncomfortable. Fast forward until about 2 months ago, my lower back was getting worse and

SIHOO M18 VS SIHOO M102C
Je viens de recevoir ma Sihoo M57, quasi pareil qu'une M18 et honnêtement le support lombaire est vraiment horrible ! Très peu de mousse sur celui-ci, j'ai l'impression d'avoir une brique dans le bas du dos, ce n'est vraiment pas confortable / agréable pour ce prix ! De plus l'assise en mesh parait

Help me choose my new SIHOO/HINOMI/FLEXISPOT/other office chair
The Fractal Refine is a gaming chair, the backrest and headrest (and the general design) are not suitable, the Colamy Atlas has a foam seat which puts me off a bit otherwise it looks good, on the Sihoo side I was just looking at the M57 which is a better version of the M18, but looking at the review

Sihoo Doro S100 - Feedback - Am I the only one failing to find any comfort in that chair?
I find this chair simply awful; it ruined my back. I'm not heavy or thick, and I feel like the lumbar “support” sucks my back in and forces me to stay upright, which tires me out enormously and makes me sit in a bad position. I used it for 6-7 months, and then switched back to my old chair (a Sihoo

m18 is okay, but the m57 and doro c300 are definitely better. more support, more adjustability, and an overall more premium feel. i’ve got the doro c300 from sihoo australia and it’s been great so far.

Recommendations?
https://amzn.eu/d/2dUgMzh £30 voucher aswell. Basic, big seat great for cross legged sitting but not adjustable, lumbar might be tad aggressive. Similar to the Sihoo M18 but arms go lower. Personally unless budget is an issue, I don't recommend this or the M18, just a basic chair. Next 3 are the one
