The seat can be installed easily and our little daughter (4) fits superbly in it! The sleeping position is really much flatter, because the head is no longer falling while sleeping forward. We had waited a long time until we have exchanged our men point safety harness seat against the Cybex, because children in many other seats so "loose" drinsitzen (even when the one we had bought five years ago for our large, in which these now nine still sits and has plenty of space ...) but in this seat absolutely everything! And through the good adjustment and the Great fits in this seat in ... strong buy recommendation comfortable!
