Instructions were easy to follow. Putting the together was not hard and it came w/ all the tools needed. Great back support and comfortable. However for a larger person with thicker thighs the edge of the seat in the front is kind of (slightly) uncomfortable. Other than that it's a great choice - especially for the price.
I work from home twice per week and the chair I was using was killing my lower back and upper back areas. Although this is marketed as a "gamers chair " it has worked wonderfully as an office chair. I love the wide seat and the separate pillows for neck and lumbar support. You can move the pillows to exactly where you need them for your height. Arm rests adjust to the exact height I need. The chair back tilts quite a bit forward and backward. I like to sit upright so the forward tilt position is great for me. This chair adjusts all kinds of ways for your comfort. Since I have been using this chair the tightness and pain in my lower and upper back have gone away. Full disclosure I also recently acquired a standup desk unit so I alternate between sitting and standing which I think also helps because it is now said that "sitting is the new smoking." But when I am sitting this chair is the BOMB. It was also easy to assemble and came with all its pieces. I highly recommend.
I am using this chair 10 hours a day now that the Corona Virus has me confined to a home office and this has made the experience great. It's tilt capacity allows for power naps and fine adjustments to the need of the home office.
The chair went together easy enough. I am 6' and 250lbs and am having problems with the bolsters being too tight and uncomfortable. It may be fine for thinner people but it is definitely not for me. This is the first chair I have felt this way in. It seems good in most other ways.
