Joie car seat

[Nat78]

Hey,
im looking for car seats for my daughter but I don’t know what the difference is between Joie i-Spin 360 i-Size or Joie 360 gti? which one is better or would you recommend?

There isn't much difference between them. Get the cheapest. The GTi is basically the original Joie 360 Spin (R44 regulation) but with side impact added (equivalent to i-Spin) and a button to press any time you want to turn it forward facing. Weight limit is 18kg, no standing height limit (fits children up to about 110cm). Forward facing is legal from 9kg (recommended to stay RF for much longer).

The i-Spin conforms to the newer R129 regulation and has a memory foam headrest and a slightly improved insert, the wedge isn't quite as chunky but it has an extra recline setting instead. Height limit is 105cm but you can use it up to 19kg rather than 18kg.

The button to spin the i-Spin is on the side whereas with the GTi it's under the child's feet and can be tricky to reach (easy when you know how IMO). The thing to control whether it can face forwards is more of a switch so is slightly less annoying and it's illegal to forward face in this one before 15 months. Again rear facing is preferred anyway.
