I think the Four Kings of chairs are the Herman-Miller Aeron, the HM Embody, the Steelcase Leap, & the Steelcase Gesture (my preference). I've not tried the Embody myself, but I'd bet it's good. HM Mirra is a close runner up. I've got maybe 11,000 hours in the Leap, it's fantastic. My Gesture is new but I think I like it more; the arms truly are great. It's really hard to guess what you'll prefer; just keep your eye out for trying out as many as you can. Also note Aerons come in 3 sizes, so maybe you like the M better than the L, or vice versa.
