ErgoMax 3D Ergonomic Adjustable Executive Swivel Office Computer Desk Chair w/High Back, Headrest, Seat Slider, Black Mesh, Aluminum Base, 52 Inch Max Height

Bought this chair purely relying on my instincts, as there is/was no review on it. I am the 1st to write a review on Amazon and I hope helpful...for what its worth. It was relatively easy to put together. Although I did install it with the seat facing the wrong way -- although hard to say now as photos on Amazon seem to show the seat installed either way ¯\_(ツ)_/¯ Then I also put the seat hands the wrong way. Needless to say, I was not having a good day putting this together. But I was able to take things apart - twice - and still manage to have a fully upright chair in under two hours. Bravo to me. It is a very comfortable chair. The seat is wide and bouncy (cant figure any other way to describe). The height is perfect for my long legs. I love that is leans back (although I keep worrying I may soon break the hinge as I dont trust my building skills). Love the swivel. Love that it is NOT a cloth/cushion seat. I've only had it a full day now, and you might have guessed I am having a lot of fun with it rolling around my covid-home-office. There were a few missing pieces - 3 nail washers, which I guess the manufacturers decided are not really necessary. I disagree, as there is a reason why they are included in the pictorial instructions. All in all, a good purchase. I hope it lasts and is durable. I'm not getting reimbursed from my job for setting up a comfortable working space during covid home-based work, so this has to be a good investment.

Overall it is good. One minor point: the installation instruction is vague and NOT very accurate.

ergomax is a top-tier chinese brand, but i highly suspect this is a bootleg. here are the reasons. 1. instruction manual is very vague, and its only 3 A4 pages. 2. the seat cushion may very easy be installed in the wrong direction. be careful 3.missing 3 washers for back rest 4.i dont see "ergomax 3d" on jd.com( one of the largest chinese online platform). the popular model is ergomax evolution, and it looks a bit different from "ergomax 3d" 5. strong weird plastic smell. not sure if it's toxic formaldehyde. -------update---------- although i suspect it's a bootleg, after 18months of using at 40hrs/week, the chair is still in good shape and comfortable. so im changing the rating from 1star to 4stars

It broken after 2 month.
