This is a good redesign. I've had a Mirra for maybe 5 years now, best chair in the house. The only issues I had were the prongs which provide the back skeletal strength broke through the mesh. As the meshing is plastic this meant a sharp pain in one's shoulder blade. The warranty covered the fix and paid for fedex to came to my house with a giant box and ship it for repair. I cannot imagine what it must have cost to ship a full sized chair! Even still I was out a nice chair for a couple weeks. Those few weeks reminded me how much nicer the Mirra was compared to my old staples chair. This redesign appears to address said structural weakness by spreading the point of contact. It also widens the usage space for positioning your back. In my Mirra 1.0 your body must be dead center else your back will be sitting over a pointy prong. It looks like this 2.0 will have a backing which folds into your back, hugging it so to say. It also appears they have slimmed the box below the seat. In general the plastic casings are slimmer and less bulky. Also of note it appears the adjustable lip where your knee joints occur has been given a longer radius of rotation. Or atleast it looks longer to compared to my Mirra.
