I bought the dog pad for use in an outdoor dog house.  The foam inside the micro terry cover is fairly dense making it more supportive than most dog pads I've seen.  I saw the product in a retail store, but, ordered online in order to get the extra large for a malamute....he loves it.  I did have a water-resistant slick fabric cover sewn to encase it for outdoor use to keep it from getting muddy.  Am very happy with the result and so is he!
