Has anyone found a dog bed that holds up to heavy chewing?

My dog has officially won the battle against dog beds. Four of them gone in about two years. Some lasted a few months, one barely made it through a week before stuffing was everywhere.

The weird part is he doesn't destroy random stuff around the house anymore. It's just beds. He'll scratch at them, chew on the seams, and eventually find one weak spot that turns into total chaos.

I'm at the point where I'd rather buy one bed that can actually survive than keep replacing them over and over. If you've got a dog that's rough on beds, what ended up holding up? Did you go with one of the "chew-proof" options, or is there another type that's worked better long term?

Also if there are certain materials or designs that seem to last longer than others. I'd love to hear what has actually held up in a real home instead of just sounding good on the product page.
