I ride a bicycle, so I am planning to get Cargo tray for the trunk. I also saw Cargo tray seatback which doesn't have a picture on the Kia website and I couldn't find one online. I did find cargo mat seat protector. Will be good to have a tray on the back of the seat.
The seatback mat is fabric but with a rubber liner underneath. It's not easily washable like a full rubber mat, but it's better than most other solutions I've seen if you want to protect your car's interior surfaces.
Thanks for the pictures. I thought they would be made up of plastic as of cargo tray. But would be still better than nothing. I have a mountain bike so much more mud. I think I will just get a roof rail or tow hitch.
