Dog bed or pad that wont get destroyed?

Looking for recommendations on a bed or pad my dog wont absolutely destroy out of spite. She’s a 50 lb lab shepherd mix that gets bored and look for a job to do when home alone so unfortunately I have to crate her. For her safety as well as my sanity and home. After 4 kennels destroyed, 1 couch arm chewed through the hole she made, and 3 curtains yanked through the slots scooting herself over to the window I went ahead and bought a Gunner for her as well as the ortho pad insert. It was not as tough as I thought and on day 1 was in a million pieces 🙃 I feel bad she’s on the hard plastic but she finds a way to shred anything I give her.
