I must admit we didn't & until recently I never even thought too (really I had never even heard of a CPST). =/ Doing a quick search of their database I've learned we only have ONE in our city of ~100k... that makes me so sad! =(

I feel pretty confident of my install (once I got our both the seat & vehicle manuals) but I think I might see about making an appt with her anyways.

Did you have your seat checked by a CPST (not just the fire dept but a certified tech)?

Here's where I searched:

If anyone knows of another database do let me know!
