My son had 3-6 years the solution xfix unfortunately I was there very disappointed with Cybex as it is supposed to go to 12 years but with 6 years, the headrest had with my son already in the uppermost position of therefore now a new forth ( actually it should no longer be Cybex) and lo and behold with the M-fix he still has plenty of room for ever upward! My daughter, we have also the same as they now bought is located 3.5 years old and too big for the old seat was. In particular, the m-fix is not as above rum Globig as the x-fix you as an adult "back out" a better look. Color blue and purple just like displayed very nicely. If the seat immediately buy again highly recommended.
