Is A King Box Spring The Same As Two Twins . A california king, with its extra length, uses two twin xl boxes. We have a king sized bed the box springs are extra long twin's.
Kim posted two images with the caption: Two twins make a king, but not just any twins will do. Hello, these two box springs have the same style metal frame.
Moving the traditional box springs around is a challenge.
Two twins can't equal a king because normal twin beds are too short (they are the same length as a full/double). I had always heard that two twins equal a king in size and this is true with 2 twin xl (extra long) mattresses (like colleges) but not with regular twin mattresses. Two xl twin box springs are what you would use for a king size bed. Boxsprings serve two basic, but important functions.
