adac do independent testing though you may need Google translate. This age group are safer rear facing though rear facing. Some rear facing seats do swivel
My son has been in this since 10 months. The ease of getting him in and out with the swivel function is amazing!!It fits really tight too with the seat belt as it doesnt just clip in it also has a device to remove any slack out of the seat belt. We also have the pearl isofix in my partners car which is much smaller and so much harder to put my son whos 3 in.
I get that swivel is easy though I much prefer safe. Rear facing is significantly safer.
Second the Joie 360, picked ours up a few weeks ago from boots, using the 10% code and extra boots points, worked out at £130 per seat (bought 2), ticks all the boxes, isofix, spins,rear facing option to 4 years. Check it out
I had these for my twins and the rotating is a godsend, BUT the ratchet system is used to secure the seat ruined my rear seat belts. And they weigh a ton. The Joie 360 is a much better alternative.
