Which chair is the most comfortable for short term use? I don't sit in my office chair for hours at a time, I'm looking for the most comfortable in terms of plushness / softness. I recently tried a secret labs titan Evo and the base of that felt like sitting on a park bench! It looks like the iskur V2 offers the most support of your range, but how does it's cushioning compare to the enki range which is advertised for comfort?
