I read a lot of reviews before purchasing this chair and although some people had issues with it, most report that they're pleased with it, and I'm definitely pleased with this chair! Solid construction, comfortable, and easy to put together. The casters are fairly basic plastic ones that work absolutely fine on carpet but if you're chair is meant for hardwood like mine, then I recommend purchasing casters meant for hardwood floors. I'm 5'2" and the chair height at it's lowest is good for me. No need to raise the height, although that function works great still. Because I'm replacing the casters for better hardwood floor ones, I've had to make sure I order the same 2" casters as any taller and this chair might be too tall for me! So heads up for shorties that want to replace them, stick with 2" or buy an office chair mat. That's my only suggestion. Beautiful chair though. I recommend it.
