The waterproof-ness of this bed is what sold me.  Every other dog bed I've had has been ruined when I had to throw it in the washing machine.  The fact that the stuffing doesn't get ruined if my pup has an accident, is also a huge selling point.  The bed is super puffy and hasn't lost its shape over the past several months of 125lbs sleeping on it every night.  Totally worth it.  (I'll probably get a second one.)
