Promising review: "You don't know it yet but you need this... This is one small product that you don't realize you need, but it makes you happy to finally have it. Our thick, pillow-top mattress is prone to slipping, so our fitted sheets and mattress protectors are constantly slipping, causing us a lot of discomfort and aggravation. It's over! You couldn't be happier! Every bed feels and looks fresh! "WIN!" mrslitoAmazon offers a 4-pack for $8.49, available in three colors.
