Patio furniture

3 year old patio furniture. My puppies chewed on them, as shown in pictures that’s the damage. It’s not so bad u can just remove the strings that were bitten. It’s a set of 4, all with cushions in good condition. No longer want them because we got our kids a big pool and it’s taking up all the yard space. We paid over 800 for them, asking for $250 or best offer.
