So I managed to fly in these refurbished seats. Some other changes I noticed:

- the headrest can now tilt forward and back
- the seat pad is slightly narrower so that it gives easier access to the magazine storage.
- the seat seems to be fixed so that it doesn't seem to be always tilting away from the from of the plane as if someone too heavy sat on it.
- the new fabric is definitely better. Easier to move around on, and doesn't feel too hot when sleeping.
