I need a deep mattress pad
I am having the hardest time getting a mattress pad for the bed I recently purchased. I have a king size pillow top mattress that is 16" deep. All of these pads that are "guaranteed to fit up to 18" deep" just barely make it around the corners and slip off easily. Someone suggested a "bed glove" which has wide elastic all the way around and fits great, but it is a few inches too small for my mattress and again, the corners just make it on and then slip off.
I've wasted enough effort, gas and shipping charges from having to buy and return mattress pads that do not stay on.
Anyone here have an extra deep mattress and any suggestions?
