The liner sets are great but a problem with the middle (Row 1) and back seat floor liners. The middle seats on our Sienna's 8 passenger seats move (slide) front and back. The raised edges on the liner row 1 blocks the middle seats from moving (sliding) forward and the back seat liner totally blocks the seats from moving backward because the liner overlaps the groves in the floors for rollers located under the middle seats. The seats have rolls and slides front and back in these groves. The back row liners should have cut outs for the groves so the seats can move (roll/slide) backwards. Front driver and passenger liners are great! Liners actually holds all dirt/debris and water from spilling over on the side. Regular liners would not.
