The chair seems to be good. I have only used it for 1 day now and it is very comfortable.  The most comfortable chair I have purchased to date.  This is important for me since I sit for 10 hours.  I’m 5.6 and I can slide under my desk with a keyboard tray without a problem.  ￼ The chair does go  higher and lower so it would be great for taller or ￼shorter person as well.   It is super soft and smooth.  ￼I love the rocking capability.   Putting it together took about 10 minutes max.  The price is unbeatable.  ￼The shipping was super fast.  It showed up in 2 days.  All in all I would definitely recommend it.
