furniture question

i have recently gotten a cat in a sharehouse (with landlord/roommate permission) and the cat has scratched one of the living room chairs on the stitching (causing slight cosmetic damager), and slightly (no actual damage) scratched another.

the landlord/roommate has demanded I buy her another 2. Im not going to put up a fight about that, I am currently trying to train the cat and happy to get another chair (although 2 is annoying but whatever). When I buy her the new two, is it at all possible for me to keep the old two?

I am potentially moving soon and seeing as how they are still fully functional and i have bought two replacements I would like to keep them but also understand I may not have any right to. Just looking for advice :)
