Finally got my Sihoo M57. Got it from mymejakerusi (
https://shopee.com.my/product/500470137/113...91-1643442880.9) instead of Aitsulab because i) they are slightly cheaper and ii) the colour I want (black) was sold out at Aitsulab.

Overall very satisfied with the purchase as many other buyers here had. The chair was not hard to assemble alone but definitely much easier if you have someone helping especially the part where you need to connect the seat back to the base.
A tip before starting assembly.... please go youtube and watch the assembly video. The written instructions supplied are very straightforward but you might miss some details even if you understand chinese. For me initially I missed out the part to install the screws together with the washers for the arm rest... end up spending quite some time there removing and installing again.

Lastly some comments for the arm rest. I rmb reading quite a few reviews saying its uncomfortable and quite hard.... surprisingly for me they are totally fine. Its not exactly hard to me, i was expecting it to be hard solid plastic but in reality its slightly soft.
Also I know M57 dont really have width adjustments for the arm rest but looking at the holes (refer above picture).... i was a bit confused. Initially i thought its adjustable so I didnt screw in tightly but then it became too flimsy. Was wondering if some lube will help make it adjustable.
Nice chair.
Looks very similar to the AM Office. I reckon all came from the Same manufacturer
