I got two of these in twin XL for the kid and guest rooms; love them. They are full bed skirts that run under the mattress, not the elastic kind that just goes around the bed frame. The point was to keep the storage bins we keep under the beds out of sight and these work perfectly. Easy to wash with the sheets/blankets when we strip the beds and it keeps the room looking nice and uncluttered. The length is perfect and just skims the floor (we ordered twin but have twin XL beds).
