This is truly the only dog mat that i have ever bought that is so thick.  I got the first small one and then got the big one.  My husband is putting both of them in the backseat of his truck, when we have to take our three dachshunds to the vet.  The little one tinkles when she gets excited (still a baby).  I can just through these in the wash.  Really nice.  I could sleep on one myself!
