Here is a side view of Sofi riding in the seat forward facing. She uses it on harness position 5 (out of 6)
Here is a front view of Sofi, harness position 5. I'm not really a fan of how high the headrest is. It looks like it needs to be lowered.
The harness is connected to the headrest. So if you raise and lower 1, you raise and lower the other. Here is how Sofi fits in harness position 4. The headrest looks much better.....
But the harness is below her shoulders :(
