After a lot of searching and after trying the well-known seat with the bulky front belt (which is indeed considered one of the best in terms of safety, but really suffocates the child in it), we ended up with the Inglesina Caboto, a very good quality seat (the belt has bothered us a bit, but it's okay until you get used to it). The recline it has is very practical, especially when the child wants to sleep. Overall, I highly recommend it

After a lot of searching for seats priced around 300 euros, we ended up with this one. It is a sturdy construction with quality materials. You can tell by their texture. After trying the child in seats with a front pillow, we rejected them because they covered our 2-year-old child up to the neck and after 1-2 minutes he reacted very strongly. In addition, I consider them unsuitable for the climate conditions in Greece.
Before the Inglesina Caboto, we used for a few months a seat of similar size but in a cheaper category, the 360, which was given to us. It was indeed very convenient for putting on and taking off as it turned towards the door. Also, due to the child's young age, he had to face backwards. Lately, we turned them forward. After some time, especially during trips, the child complained and wanted to get out of the seat, resulting in whining and crying for a long time.
With the Inglesina Caboto, the child did not complain at all during consecutive 3-hour trips! He sleeps comfortably, has comfortable cushions, and good side support for both the body and the head. It also has a slight recline that is enough for the child to sleep. In short, it is worth the 300 euros and we are completely satisfied with the purchase. The only negative is the lack of instructions on how to remove and wash the fabric and straps if you want to.
