The feet on this rack are small bamboo pegs that stick off the bottom.  I have wood floors, and I had to find some small tack-in feet caps to put on them so they wouldn't scratch.  I was hoping to find some little rubber caps, but they're pretty small pegs, and I didn't have any luck.  

Pros: Food value, easy to assemble, quality for price
Cons: could use some sort of covering on the feet/pegs
