This is an interesting recent article on the ethics of buying replica furniture. As future interior designers/architects you may work on projects where this becomes an issue.
As noted in the article:
“Replica furniture is made with so many cut corners that it is very quickly going to be added to the rubbish pile. It damages the integrity of the original designs, which yes, are expensive to purchase, but the creators have put so much time, money and resources into coming up with new techniques and products.”
