Very little pieces to put together and the directions were great. Chair is comfortable I tried it in the store. It says it has a 7 year warranty and honestly that is the only reason it made me buy it. It will be used every day for 8 hours (advertised with a 5-10 hour seating) but the mesh makes me wonder; it seems strong but I don’t know how long that will last.
Landed on this chair after trying several different models in store. This one is perfect for me it provides a lot of tension in the back and keeps me upright. You can adjust that if need be though. The quality is great and the warranty is 7 years! My only gripe as some others have mentioned is the chair sometimes slightly rocks forward when seated. It's not something I notice unless I'm paying attention and it doesn't bother me and I would buy this chair again if I had to but just something to point out if you're OCD like me. I think this has to do with how you place the seat on the base wheel during initial construction. Overall 5/5 and would highly recommend.
I definitely recommend the chair -- very comfortable and versatile. Took about an hour start-to-finish to unpack and assemble for this 73 year old fellow (me) and it honestly was easy!
