Bunk beds are most commonly sold in sets of two beds, although there are cases where trio bunk beds can be purchased. Bunk beds are sold in twin sizes as well as full sizes. The choice on some designs are also available for a full size mattress on the bottom accompanied by a twin size mattress on top. Full size bunks are a good choice for larger children or teenagers if the space permits.
Most bunk beds use what is called a "bunkie board." These boards lie around the edge of the bunk bed frame and help take support off the bunk bed frame. The bunkie board is a thin yet durable flat piece of wood that is a substitute for a box spring or slats. Bunk beds are made of either a wood or metal type frame ranging in quality depending on the materials used. Built-in slats are more common on metal-frame bunk beds, rendering a bunkie board unnecessary.
The bunk beds are space savers for most families with tight living quarters. An additional benefit of bunk beds is the ability to separate the two bunks into their own freestanding bed frame, which is useful in the event you move to a bigger home and the children no longer share a room. Bunk beds also provide plenty of underneath storage. Some bed bunk frames have storage compartments or actual drawers that complement the frame aesthetically.
Many advantages exist with bunk beds, but at the same time there is a concern about safety and kids climbing up and down the ladder. A level and sturdy base for a bunk bed ladder is essential. Bunk beds also come equipped with guardrails around the bed's perimeter that prevent people from falling out of the bed. A stationary bunk bed ladder is recommended for buyers who are concerned about the ladder's stability.
