The bottom feet are not anti-skid

Maybe I'm missing something but when it says anti-skid I was assuming it wouldn't slide all around my table. I don't understand why there's anti-skid in the phone rest and not on the bottom. Besides that it's made of metal , and is replacing my current plastic phone stand, but I wish I had known that the anti-skid was not applied to the bottom I would have got a different stand from a different retailer.
