ErgohumanEurotech Seating iOO Chair, Black

Unbelievably hard assemble process. I have assembled all my furniture, but this chair is very hard, especially the caster!But after you put everything together, the chair is awesome! You can adjust the chair based on your own needs. It's perfect for my home office!

The only reason I am giving this a three is because the ad is misleading and false advertising. The head rest is not included and there is no way to connect with them. Looking at the product details it doesn't say anything about the head rest being sold separately. I would appreciate is Eurotech would contact me to correct this.

The mesh bottom version of this chair is one of my favorite chairs of all time, but I received the felt/cushion bottom version which I honestly really found uncomfortable. While it has the support of the other version, it didn't have the comfort of the other version, and I was super disappointed when it arrived. I likely won't be ordering from this company again until I can be 100% sure I'm getting the right product

Terrible low quality chair for such a high price!Almost hurt myself falling backwards when the supplied bolts fractured !Stay away from this !

I'm currently sitting in chair number 2 and it seems great so far (I just put it together a few hours ago). Very supportive and comfortable and lots of customizable adjustments. My only complaint so far would be that the arm rests move inadvertently if you put any real pressure on them, but that's not a huge issue. I'll revise the review later as I get more time in the chair (I'll be in it most of the day, 5 days a week).But one big word of warning. I jumped on a low price and when the (first) chair arrived, the box looked really really beaten up with multiple labels all over it and I knew there would be an issue. It was clearly a used item and the chair back was literally cracked down the middle (which I unfortunately didn't realize until I got to the last step putting it together). The fact that this somehow got repackaged and sent back out as new was very disappointing. But Amazon took it back no problem and the replacement is in mint condition.
