Suggestion for best office chair
 

I want the best office chair I can get - ideally a swivel chair on wheels. When it comes to my back, and relaxing in my home office for much of the day a number of days per week, expense is not a big factor for me.

The issue: I do not spend enough time in offices generally, and don't have a good sense of what is comfortable, physically supportive for my back, etc... outside of the obvious candidates.

What I have at this time is an older version of the Steelcase Cachet, which is fine, except it is literally failing from years of use. My default is to opt for the same thing again, but I'd enjoy other suggestions.
