I’m not an ergonomics expert by any stretch but for the price of this chair I have zero complaints. It’s miles better than the old office chair I used to have (also from Staples) which was faux leather with foam padding versus a mesh. With this chair I don’t find myself slouching as much and I don’t feel like I have to prop my feet up to keep myself from sliding off. It also keeps me a bit cooler than one without any mesh or other ventilation. It would be nice if the armrests were slightly wider and the neck/head support could do down a little more but those are very minor things.
The chair is comfortable and holds up. Wasn’t too difficult to put together. Only downside as you’ll read in other reviews is that if you’re taller than 5’10 the headrest is in your shoulders and can’t be adjusted away. Likely will remove the headrest
