Large Tempurpedic dog bed insert (San Tan Valley)

43" × 54" × 4" Less than a year old, I broke the zipper taking the cover off so I had to buy a whole new bed.
The marks on one side are not from accidents or anything nasty, my dog would often take her chew bones on there.
Free, email for address to pick up.
These beds are $150, I don't want to toss this if you can use it!
