I work from home and had a chair that was not good for my back at all. Having to sit for long periods of time put a toll on my back and as a result my posture was starting to suffer. For the past few weeks I have noticed such a great difference with my back and working became so much easier than before. This chair is good quality, it’s well made, highly functional, and very comfortable. All the functions work as they should and I had no problem putting it together myself. It took maybe about 30min. I do think, however, that’s the instructions could have been a little bit more clearer for a couple of steps, but overall it wasn’t to bad. 
Side note: it does come with wheels. I have not yet put them on because I have carpet floors.
