i'n confused. my son is riding FF in a FPSVD & he is close if not need the top slot. but i can't tell. i stuck a ruler in the slot & his shoulders are just shy almost touching the ruler but the ruler is angled up because the seat is angled. i figured this was fine HOWEVER i remeber looking at the marathon manual (i know not the EXACT seat but still a britax) & the figure on pg 7 that shows which slot to use they use the FLOOR as the straight line to compare it to. the manual also says this......referring to using the seat FF "when the harness straps are located in the nearest slots at or above the
child’s shoulders, parallel to level ground (Fig. B)."if i bend the ruler to be level with the floor then the harness needs to go up for sure.
what should the ruler be parallel to the floor or perpendicular to the seat???
