I had one on a prior vehicle and the stitches ripped out of the seat attachment super easily. hoping I can get an exact model referral that someone's had good success with!I have one from Amazon. Search for pet backseat hammock. Should be what you're looking for.
I have that one, we just used it for a 7 hour road trip in my fiancée's CX-5, works great.still be interested in your feedback. is this the one you picked up? it seems to be the best reviewed/best value.
