One of the real benefits of the QF Shybeds and CX seats (and - for that matter - any other product with the hard shell backing) is that you can use the shell infront as a handle to make getting up / down easier. Saves the person getting the sh!its when the back of their seat is moved and jerked.
Perhaps willyroo's suggestion about row 23 may not be so good as the lack of seats in front may make getting up / down a little harder?
Those who are of limited mobility certainly will not be allocated an exit row (row 16).
