We have Four of these in our Van.
They work AMAZING.
Two of them are hold overs from our Subaru Tribeca. They are VERY durable. We have three kids. My wife's Tribeca was TRASHED when we sold it for the Pacifica (quite the expensive detailing bill), but the seats under these Summer Infant Elite DuoMats was PRISTINE like we just bought it.
I was just about to buy this one but I noticed that yours has better padding. Do you happen to have pictures of it installed in your Pacifica so I can get a better idea of coverage?
