Double Seat Mat, 21" deep, 38" long.

The unique sized BusterBoy Double Seat Mat measures 21" x 38".  Made especially for heavy-duty trucks with split back seats and travel vans.  You can also use them to partially cover a standard bench seat. 
 
BusterBoy Mats are made with a top surface that gives traction for a dog's nails to grip, while the underside of the mat has a non-slip surface, so the mat itself doesn't slip or move on the seat.
