I am thinking about buying a Leaning/Perching chair which encourages a 130-135 degree hip to torso angle instead of the ususal 90 degrees.
Question #1: Is a Leaning/Perching chair an ergonomically good choice?
Question #2: Is the angle of the foot important? There is just one Leaning/Perching Chair that supports maintaing ankle at 90 degree resting angle. It is the Locus Seat by Focal Upright.
