"ERGONOMIC"?!? For what scenario? Reclining back in a home theater? I bought this to use as an office desk chair to work from home on a computer. To understand everything wrong with this chair, simply refer to the diagrams in the instruction manual that comes with it. Sitting in an appropriate up-straight posture, the chair back is angled way back. You can tilt back even further back (also tilting the seat base, to which it is locked at that angle), but you can't bring it closer. To be fair, it's rather comfy, say, as a recliner to lean back and listen to music or something, but that's not why I bought this. I need to figure out how to return this and find a different chair. :(
