I love our Snoozer seat. The strap that attaches to the harness goes around the "lap" part of the seat belt. This lap part is also the part that goes around the back of the seat and fastens to the car. The shoulder part just goes behind the seat. Hope that is clear as I don't want to confuse you. I had the same question when I got ours. I have 2 little ones and they both fit it the regular size seat, side by side and they love being able to see out the window. |
