What is a Bunkie Board? Benefits, Drawbacks and Types


Most of us have used various mattress foundations, such as box springs and slatted frames, in your beds. Yet, what is a Bunkie board?

Bunkie board” refers to a thin, flat board between a mattress and its supporting frame. Fabric covers prevent the mattress foundation from getting caught on things and ripping.

Below, we’ll explain what a Bunkie board is and what it’s used for, as well as its pros and cons so that you can make an informed choice.

What Exactly is a Bunkie Board? – Detailed Answer

A Bunkie board, also known as a mattress foundation or a sleep surface, is a thin, flat barrier that separates your mattress from the floor or other surface it rests on.

It is compatible with all bed frames, including wooden, metal, solid platforms, box springs, and slatted bases.

A Bunkie board gives a mattress support, which makes it last longer. It is usually made of wood, plywood, particle board, or metal with a fabric covering. It is normally about 2 inches tall, while a box spring is much more significant.

A Bunkie board keeps a traditional mattress from sagging, which would happen if slats only held it up. It’s a great choice when you don’t want your bed too high.

Different Kinds of Bunkie Boards

Particle boards, plywood, and solid wood can all be used to make bunkie bed boards. Each material has benefits and drawbacks.

1. Plywood

Plywood bunkers can cost more than particle boards despite being robust and lightweight. Several thin layers of wood are bonded together to create plywood.

2. Particle Board

Particle boards are made of wood chips that are stuck together. Bunkie boards made of particle board are the least expensive option, but you should be careful because they may pose health risks.

When the particle board inevitably disintegrates, potentially dangerous formaldehyde fumes will be released. Knowing the form of formaldehyde used in producing particle boards is essential for reducing health risks.

Particle boards are made with phenol-formaldehyde (PF) or urea-formaldehyde (UF).

But because urea-formaldehyde gives off more dangerous fumes, phenol-formaldehyde (PF) is safer.

3. Solid Wood

Bunkies made of solid wood are strong, but they are also heavy and can be expensive. In contrast, Bunkie boards are solid and long-lasting due to their construction.

Even though most people think they are expensive, the extra cost is worth it because the bed frame will last longer.

4. Steel

Another option is a steel Bunkie board. They’re the heaviest but strongest. Unlike other Bunkie boards, they are built of steel slats in a steel frame. Some have fabric covers.

Steel Bunkie boards are suitable for heavy loads. They work well for bunk or loft beds.

Unlike wood, they resist fire, water, and termites without treatment. Temperature and humidity won’t affect them.

Steel Bunkie boards harm mattresses. Even with a fabric cover, they may poke through the mattress. Several modern mattresses, including memory foam and latex, are prone to this. Thus a steel Bunkie board may not work with them.

Moving with steel bunkies can be problematic. Steel Bunkie boards have the additional drawback of being heavy and more challenging to handle and transport.

Moreover, the cost is higher than that of plywood or particle board.

Benefits and Drawbacks of Using Bunkie Boards

Bunkie boards are no longer just for bunk beds. There are Bunkie boards for all sizes of mattresses so that anyone can use one under their bed.

They often help the mattress stay firm and last longer. Other essential benefits of the Bunkie board are:

Pros of Bunkie Boards

  • Bunkie boards lower platform beds compared to box springs. Since the most common size is a two-inch Bunkie board, they are pretty low profile.
  • They are strong and fit any size bed due to their wood design. Hardwood Bunkie boards give durability and support to platform beds.
  • Bunkie boards range from twin to California king. The considerable selection makes them accessible to most individuals.

Cons of Bunkie Boards

  • Water and changes in temperature can hurt bunkie boards made of wood. In a humid climate, the board may bend over time.
  • A solid wooden plank between the bed frame and mattress might lessen ventilation. The mattress can trap body heat, making molds and allergies thrive.


What Is the Price of a Bunkie Board?

Bunkie boards cost anywhere from $50 to $150. The price will rise because of the bed’s size.

Do Bunkie Boards Come in a Variety of Sizes?

Bunkie beds come in twin, complete, and king sizes. Split queen and king Bunkie boards are available.

How long can a Bunkie board be used?

Bunkie boards last 2–3 years. Metal and solid wood Bunkie boards survive longer because they can hold more weight and resist alteration.

Where to get a Bunkie board?

Bunkie boards are sold in the majority of furniture and mattress shops. The board can also be ordered online and shipped to your house.


There are many reasons why people choose Bunkie boards, but if you’re looking for a way to sleep better, you might want to buy one. Box springs have been used as mattress bases for a long time, but Bunkie boards have a more straightforward, lower-profile look.

A Bunkie board was initially made for a bunk bed, but it can also be used with most other mattresses. They also give your mattress the right amount of support.
