My employer sent me a Steelcase Series 1 to use at home and it's total crap compared to the Leap. The back adjustment is either 89 degrees (totally upright) or like 10 degrees (basically laying down), nothing in the middle. Those numbers may be approximations based on my feelings.
I have a $40 chair I bought on Amazon and it's almost as good as the Steelcase Series 1.
But let me tell you something: I recently bought a split keyboard (Dygma Raise) and it allowed me to change my posture significantly and adjust the chair height, and it made me much more comfortable. Chair height is such a changing factor, and pretty much every one supports it.
I am also considering buying a keyboard tray to attach under the table (just search for Keyboard Tray on your favorite sales website) so I can lower the chair even more.
I am also considering a foot rest.
So, to conclude: comfort is not only the chair, but everything else around you, which makes you sit differently.
