Nothing is more annoying than dropping a cup of hot coffee all over your seats from a bad cover lid. Or your kid is all wrapped up with baseball and his cleats are full of red dirt, pants, shirt, all over the seats it goes.
A good set of seat covers will do the trick. I like using the water proof neoprene covers. They come in all different colors, patterns and for a great value. I like using Quadratec as they have a gret selection for a fair price $199.99.
I have spilled plenty, lots of dirt, I do not mind now throwing something on the rear seats as these covers kick butt.
