This bed fits well into the crate in the car and the dogs are comfortable on it.

I have purchased 3 of these dog beds because they're easy to wipe down or shove in the washer (I only wash the external cover). They are definitely waterproof as the inside of the cover feels slightly rubberised, although once washed the green side becomes quite absorbent. Wet doesn't go through it just spreads on the surface. My one and only gripe is the stitching. it's terrible. I'm constantly having to stitch around different parts of the bed. If the manufacturers can sort this out the beds would be the best I've ever had...
