OK. Here are my top 2 picks now. I think the Zody is adjusted with forward tilt. When nobody is in chair looks tilted way forward. When sit in chair is more upright.
Study the way I sit in the 2 chairs and which one looks best?
Gesture has the amazing arms that swivel in close to body. Good thorasic support but maybe not as much lumbar; but is up against my lumbar when I put my hand back there.
But saw versions with optional lumbar support last week and it felt good: see shots "gesture with lumbar" near end of folder.
Zody has both lumbar and pelvic support.
