Lightweight, comfortable, flexible, and looks secure - without being something "inflated" that caught the eye in smaller categories.
The back "plays" a little more compared to the previous category (9-18kg), but firstly it is expected - to adjust to the seat and secondly, as the child grows/heavies, the movement decreases.
Quality materials, beautiful colors (forest), and a price that is worth it - we are talking about the safety of the child.
The recline, as commented by other friends, is good, especially in combination with isofix+seat recline.

We have it for a year. Very comfortable to install. Lightweight to carry. It has 2 cup holders. It easily secures the child with the car seat belt. The recline it offers is quite large for the child's stable sleep. At first, I thought it didn't have a great recline suitable for sleep. Then I discovered that besides the upper handle that provides a slight recline, there is the lower handle (of the isofix) that offers a much greater recline. With the 2 reclines, it becomes perfect for sleep. I highly recommend it. Also, the fabrics and plastics are of excellent quality.

After a year of use: Relatively good price, but there is the Peg Perego backless booster seat (the shuttle) for 60-70 euros that does the same job. Almost no recline, and combined with the lack of support, it makes it impossible for the child to sleep (you constantly look back to see if the child is still in their seat). Very easy installation (compared to the previous Peg Perego stage we had experienced) and the child can climb up on their own. If I had to choose again, I definitely wouldn't get it again.

As a first impression, it was very good.. However, I realized along the way that the bottom part of the seat does not have side protection, resulting in the child's legs constantly slipping to the right and left. It tilts to the side when sleeping, the head falls and you constantly have to check to make sure it is in the right position. The recline it has is so small that it is almost negligible... I do not recommend it...

Lightweight seat with easy installation and very good reclining. Comfortable for the child and safe. It has an isofix system, something that other seats in this price range do not have. The child seems to be securely fastened with the car's seatbelt. It has a small size and can be easily transferred to another car if needed. The quality of the materials seems very good. The rest remains to be seen... For now, I recommend it and give it four stars because I am waiting to judge it over time.
