This has been so great! My son spilled some water on this before my husband was able to put the mattress back on, and it didn't get to the box spring at all! We don't have any sort of sham for our box spring, and this makes it so that we don't need it! It is a nice smooth fabric. Very aesthetically pleasing. Our house tends to retain water really well (too well if you know what I mean), and it is so great that I won't have to air off our box spring anymore!! It is easy to put on, and has a nice zipper for easy access.
