Puppy or senior dog bed / pack n play mattress

This is a pack n play mattress I used for my puppy as he was growing based on a hack I saw for making life easier as you can buy water proof sheets for this and switch them and wash them super easily. Mattress is in amazing condition, I can include the sheets I have as well but they are not in good condition (some holes/ stains). Easy to buy new waterproof sheets online and this set up makes cleaning up accidents etc very easy for puppies or senior dogs. I would double layer and just pull the top layer to put in the wash. 36x26 inches Queen and Portland, Toronto
