What kind of foam should I use to replace my couch cushions? - cushions of the liver

My dogs have destroyed two of my three couch cushions and will be one or two months ago, we have enough saved for a new sofa. I've tried to make new pillow, but there are about one million species of foam there. Can someone enlighten us on what type should I choose? Our sofa is widely seen as a cushion will be very difficult.
