Refurbishing Particle Board Furniture

When I moved into my first apartment many years ago, I didn't have a lot of money so I purchased quite a few pieces of furniture made of particle board. Unfortunately, they are starting to show their age. Since the holidays are approaching, I'm refurbishing my old particle board furniture instead of purchasing new items.

What do you do with refurbished furniture when they start to show wear and tear? Do you prefer to repurpose the furniture you have or buy something new?
