The most basic bed frame is called a frame-only, simple, or traditional bed frame. Usually made from metal, it has legs that raise it up from the floor and may be on wheels that allow it to be moved easily. It doesn’t have a headboard or footboard. One of these will need a box spring as well as a mattress.
The advantage of a simple bed frame is its low cost. On the downside, it’s utilitarian rather than stylish.
