sihoo doro c300 pro ergonomic office chair

I took the C300 Pro to work, where I sit for eight hours a day. It is way more comfortable than my basic office chair, and its high-tech look gets plenty of attention from everyone else in the office.

    This is a very decent chair at this price point ($350). Most parts can be easily adjusted and a lot of features are non existent on a competitor brand that we all know which is yet an order of magnitude more expensive than this. Will see how the durability lasts.Things I like:- Much better lumbar and arm support than $200 ones- 6d arm rests are surprisingly good to match my desktop height. A lot of other chairs I used simply fall short on height and tightness adjustment (ie can be adjusted inwards to point to my keyboard better without compromising seat width)- all in one tab adjustment is great no need for remembering which one is for which- Decent finish and easy to assemble as most parts are already preassembledThings I wish can be improved:- due to sheer number of adjustments possible, the chair slightly wobbles when you move on it (esp. the seat back). Wish the tolerance between parts could be better.- the finish of the plastic parts seems a bit rushed. The back support piece is warped here and there (see 2nd pic) though interestingly they cannot be seen from another angle (see the 3rd pic). Not a big deal but impairs the look of quality.- the lumbar support is self adjusting but wish the default height could be higher. Right now even the highest position is slightly lower than expected.- not sure if asking for too much but wish the back angle could be negative (inwards when sitting straight) - that would be a great feature to offer better back support at work as right…

    Well built and comfortable chair, took a few days to get used to. can really feel the support on my back. Have a herman miller aeron at work and i think for most people this is the better choice considering the huge price difference. i wish they give the leg rest like the chinese version does

    I have no problem with the seller of this item. Everything was packaged neatly.This chair is ALMOST the perfect chair. It is SOOO comfortable! I would give 5 out of 5 stars, but the lumbar support is so unforgiving. I've tried every combination of positions. I'm going to give a 3 out of 5 star for now and continue to try it out for a bit.If I could remove the lumbar support, that would make this chair perfect.Edit: I'm talking to customer service about the chair right now and they've been so helpful. Raising this review to 4 stars just because of that.
