These are two metal frames for twin beds that can be used together or separately to make a King size bed or two twin beds. The mattresses come with their own mattress covers. The bed folds for easy storage and sits a few feet above the ground so that there is room for storage underneath as well. Can come with pillows if needed. Great if you need a guest bed, but also works well and is comfortable enough to be your main bed. It folds so it can fit in any size car. Pickup will be in Mountain View.
