Aftermarket Seat Cover, Side Airbag Seam, Help Needed

For those who have or had aftermarket covers made for Prius (GT, Clazzio, Wet Okole, etc...), can you tell me if the side breakaway seam on the cover sits right over top of the side seam on the OEM upholstery?

Might sound obvious, but, I can feel the slit in the foam where the airbag deploys, and that slit is a couple inches behind the side seam (driver's seat towards the door pillar) of the OEM upholstery.

Why asking? I'm considering to cut a slit in the one-size fits all cover I've had for 2 weeks. Don't want to cut over the foam slit when it should be over the fabric seam.

Thanks in advance!
