White melamine shelves that adjust and so you can add more of them than come with the shelves . Clean, no worry about staining and easy to wipe dust off if needed. Heavy enough that you don't need to attach to a closet wall but if outside the closet, you might attach so they don't tip out and land on some one, like grandkids who want to climb up to see what is on the top shelf. If they are in a room remember that sun can fade the fabric so cover with something to protect from sun and dust. Jan
