Will it hold my blanket too?

Yes, there is enough room in the Better Bedder® to keep your
blanket and other items. Remember, the sides of the Better Bedder® are not as tight as the corners; so along the sides of your mattress, your sheets and blankets are tucked in but not gripped. And yes, even with a blanket, a mattress topper and a mattress pad, all the bedding will stay snug! View Our Video!  If you have a removable mattress topper, the Better Bedder® should sit two inches below the top of the mattress.
