Can You Use a Regular Mattress on a Bunk Bed?

Sizes

• Bunk beds are sold in two sizes, twin and full size. A twin-size bed measures 39 inches wide and 75 inches long, while a full-size bed is the same length but 54 inches wide. The bunk beds can be manufactured in several combinations that include a pair with full-size beds, a pair with twin-size beds or a combination of a twin on top and a full size below.

Foundation

• The bunk bed mattress is the same type used on a standard bed frame and foundation. The difference between a bunk bed and standard mattress frame is the foundation. On a standard mattress you can use a box spring as a support foundation or slats. On a bunk bed, you can use slats or a bunk board, which is a flat piece of wood beneath the mattress. A box spring is not designed to be used on a bunk bed.

Frames

• Bunk beds are manufactured in two primary types of frames, metal or wood. Most low-end and inexpensive bunk bed frames are made of metal and include built-in slats and a foundation. The slats on metal bunk beds are welded into the frame to provide support. These will work fine for any type of mattress. Better quality bunk bed frames are constructed of hardwoods such as oak and maple, which are more resistant to everyday wear and tear. These frames can be used with bunk boards or slats.

Mattress Types

• Any mattress can be used on a bunk board. Manufacturers sell mattresses in three types--spring, foam and latex. Spring mattresses work best with box springs, but slat and bunk board bases are also suitable. Latex and foam mattresses better conform to the slats to provide a greater sense of support and are less prone to shifting.
