The adjustment of the models are identical. The backrest can be tilted, the head restraint is in the highest, and - for a little nap - also adjustable triple backwards. The seat adapts well to the contours of the car seat. Since the head protection is somewhat less than the X2, the child can IMHO easier to pack in the seat, or you can spread more easily to angurten. The processing makes a very stable impression and the seat is - as far as we can tell - cozy for a child seat.
This model is without Isofix. There are both front seats as well as Isofix model ("fix"), which is naturally more complicated with frequent vehicle changes. Drivers with leather seats, I recommend the "protective cover for rear seat" of Reer, the already from 7, here - there.
