Depends on if you want it rear facing or not. We’ve got the Cybex solution T i-fix, they don’t rear face but I liked that the wings on the side move with the headrest (I’ve got wide shoulders so think they might), and it’s one of the only ones where you can recline their headrest if they fall asleep
Cuggl isn’t a recommended brand, they only do the legal minimum of safety testing. The Joie seats are tested to a better standard. Be aware though that the ones that say they do toddler - 12 years are usually making some kind of compromise to be able to offer that. Often you can only use them with a harness until around 18kg and then have to use as a high backed booster which lots of children aren’t really ready for yet by the time they’re 18kg. In terms of safety it’s better to get a dedicated toddler seat and then switch to a high-backed booster when they’re around 6 years old.
Agree with @Sade we have the same for our 6wk old LO and it works great. I'd say go to john lewis and ask for their free demos to get a feel
I recently bought the Joie I-spin XL from John Lewis, it's straight forwards to use and can be used rear facing and front facing up until 12 years old. So far so good
