Very comfortable once fitted but awkward to fit.
A bit awkward to fit but once in it is very secure and my little girl seems very comfortable in it. Haven’t worked out how to tilt it yet. More homework for me! Definitely won’t be swapping to other car though so think may have to purchase a second one.

Nice seat although no cup holders.
Great seat and easy to fit. Nice functionality and the tilt back. Only negative is there are no cup holders.

Do it ! Buy it ! Honestly, this is it
Excellent in many ways! We went from London to Liverpool and my 3 years went to sleep within seconds and sleeped the whole journey. This means she was comfortable and cozy. We had another chair prior to this one that I have sent back.

Brilliant car seat !
The ADVANSAFIX Z-Line was easy to fit in the car with ISOFIX and top tether. It is easy to do by pulling the lever at the back to extend the arms and then connecting to your ISOFIX points. The top tether hook attaches to the top tether anchor in your car which is usually on the back of the seat. Installation when used as a high back booster can be done with ISOFIX and the vehicle seat belt. Then to finish just unscrew the side impact cushion. This took about 5 minutes so it was super easy to install. The harness pads are soft and supportive and covered in neoprene which stops the straps from slipping in an accident. The harness height moves up and down smoothly with the headrest when you press the button at the back. Both my 3 year old and 6 year old love this seat and find it very comfy. It’s ideal that the recline positions work for both harness and belt strap as my older child still naps in the car and in this seat her head doesn’t fall forward. To swap from harness to strap It's easy just follow the guide to put the harness away by tucking it into the inside of the car seat. Great that nothing needs to be removed and potentially lost for future use! The SecureGuard adds an extra contact point for the 3-point belt to pass through which helps keep it in the best position over the child's pelvic bones instead of slipping up over their abdominal area.It flips up from the bottom, again just follow the instructions. There’s also a shock absorbing strap pad for the chest and shoulder part of the seat belt which is tucked away in the pocket at the back. The only feature it lacks is a cup holder ! Overall we’re very happy with this seat and will be using this until they’re both 12 years old. Would highly recommend !

Well made, comfortable and safe
When it comes to child car seat safety and comfort is very important and worth to buy the best child car seat even if it's a bit more expensive than other brands on the market. Britax Römer is a well knows german brand in the market and has a good reputation which is absolutely relevant, this ADVANSAFIX Z-LINE model is by far the absolute best car seat we ever had. We are using it in a 2016 Mazda 3 car and in a 2014 Honda CR-V and fits perfectly in both. But I’m very confident this can be fitted in any other car, thanks to the robust and safe ISOFIX installation. I love the fact that after our baby will outgrow the seat, we can convert into a child booster seat with backrest and we can still continue to use up to the age of 10/12. No need to buy another child seat for up to 9 years which is brilliant and saves us so much of money. The hight of the headrest and is adjustable. My only problem with this seat is that doesn’t have an armrest with a cupholder, it would be great once our baby will be older enough to use it as child booster seat. Other than this I really like the design, looks and feels it made from high quality and unbelievably soft materials to make it very safe but also comfortable, our baby falls asleep very easily in it even if we go for a longer journey. I would absolutely recommend this, but even with this fantastic child seat you will still have to drive safe!!!

Ravie de mon achat, qui m'avait été recommandé par Securange. Siège relativement léger, bien fini, confortable, très simple d'utilisation. Mon titi va voyager en sécurité et bien installé!!! Et pour ne rien oublier reçu avec 48h d'avance malgré la tempête et jour férié, par UPS qui a pris grand soin du colis!!! Vraiment très heureuse

Perfecta , cómoda y amplia, nos decantamos por esta silla porque tiene arnés de tres puntos, se la compré con 5 años y pesaba 18 kg ahora con 6 años y 21 kilos puedo seguir usando el arnés, cuando esté un poquito más mayor se puede poner cinturón normal. estéticamente es muy bonita. Tenemos más productos de esta marca y estamos encantados.

Für uns war wichtig: leichter Ein- und Ausbau, Sicherheit und Sitzkomfort der Kindersitz lässt sich super einfach und schnell von ein in das andere Auto umbauen mein Enkel sitzt sehr gut, beim schlafen fällt das Köpfchen nicht nach vorn, eine leichte Liegestellung ist auch möglich Nach zwei anderen Kindersitzen, bei denen ich fast die Krise bekommen habe mit dem Einbau und Festschnallen, habe ich den Kauf bei diesem Kindersitz nicht bereut.
