I have been looking for an office chair that tics all my needs.  Comfy, arms, lots of adjustments for my petite body, but a big enough seat cushion so I can sit cross legged when I want to. I never would have thought a "gaming" chair would be that chair; but here we are. 
Tilts forward, wayyyy back, foot stool/rest, lumbar and neck cushions, up, down, spin around. AND, the seat is big enough to do cross legged meditation when work gets to be a bit stressful. This is the managers chair I never knew I needed. 5 star love it. Delivered earlier then expected by Wayfair. PS. the lumbar cushion has a vibrate mode. Not in the description, but a cool surprise.
