Hi Anna,
not sure if you're still needing advice but we got the maxi-cosi priori. It has really great safety features such as plenty of padding (side impact protection and head protection) and padded shoulder straps which adjust to 3 positions. Fully reclining seat - with 5 different positions and its really easy to adjust - one hand mechanism.
My 2 yr old daughter seems to really like it - she loves the fact that she can see out the window and must be comfy in it as she falls asleep pretty easily in it!
Its also really easy to clean! I haven't (yet) had to actually remove the seat cover to wash it and after 1 yr it still looks brand new!
There are great clips on the side of the seat to put the straps into (once you've taken your baby out), which are a brilliant addition as I never struggle to find the straps underneath my daughter when I've put her in.
Hope that helps!
