High-end ergonomic chairs

[Terry]

Does anyone have any experience or advice about high-end ergonomic chairs?

I have eliminated the Herman Miller Aeron Chair because I frequently like to sit on one leg or with both legs up in a sort of lotus position and the net seat just isn’t comfortable for that. I have also seen reports that the fabric is so rough that it actually wears out pants very quickly.

Anybody tried the Herman Miller Mirra chair ?

The Leap chair and the Think chair, both by Steelcase are the two that are highest on my list right now.

I’m also giving serious consideration to the Freedom chair but am uncertain that the idea of not having adjustments and/or locks is such a good idea, although the chair has won all sorts of awards.

So, anybody have any experience or insights? Or something I’ve missed?

Thanks.
