That's the “Snoozer Luxury High Back Console Pet Car Seat” – amzn.to/2MnglBj
Daisy loves the high side walls much better than the mostly flat bed we had in the truck originally. It straps to the console as well as the floor of the truck, and has a tether you can clip to a harness.
Note: The dog bed has been in and out of stock a lot recently. If its out of stock, just keep checking back.
