Can you use carpet pad under an area rug?

Yes, you can use carpet pad under an area rug. Doing so can provide additional cushioning, prevent slipping, and extend the life of both the rug and the flooring underneath. It's important to choose a carpet pad that is appropriate for the type of flooring you have to avoid damage. Always ensure the pad is slightly smaller than the rug to prevent it from peeking out at the edges.
