What is a Bunkie Board?

A bunkie board is a thin platform used to support a mattress.


A bunkie board is a flat, thin board made of wood or a wood composite, designed to fit between a mattress and its bed frame or base. Often covered with fabric, the bunkie board provides a stable support for the mattress, helping to distribute weight evenly and prevent sagging. This is particularly useful for foam mattresses or other types where direct support across the entire surface is necessary for the mattress's longevity.

Bunkie boards are an ideal solution for beds that require additional support but cannot accommodate traditional box springs due to height constraints or design. They are particularly popular in minimalist designs, loft beds, bunk beds, and platform beds where keeping the mattress low-profile is desired. Despite their slim profile, bunkie boards are built to be sturdy and durable, offering a simple yet effective way to enhance sleep quality and mattress lifespan.

Moreover, the use of a bunkie board can benefit all types of mattresses by providing a solid foundation. This can help in maintaining the structural integrity of the mattress, reducing wear and tear, and potentially extending its life.


Bunkie boards can be found in various settings, from children's bunk beds to minimalist adult bedrooms. They are especially popular in scenarios where space is at a premium, or a lower bed height is desired for aesthetic or practical reasons. They're commonly used in combination with platform beds and other furniture where a box spring is either too bulky or unnecessary.


  • Can a bunkie board replace a box spring?

    Yes, a bunkie board can replace a box spring, especially in cases where a lower profile is desired or when using a bed frame that does not require the additional height a box spring provides.

  • Are bunkie boards suitable for all mattress types?

    Yes, bunkie boards are suitable for all mattress types, providing essential support that helps to maintain mattress integrity and prolong its lifespan.

  • How thick is a typical bunkie board?

    The thickness of a bunkie board usually ranges from 1 to 3 inches, making it a low-profile option for mattress support.

Practical Application

When choosing a bunkie board, measure your bed frame or base to ensure a perfect fit. It's also important to consider the board's material and durability. If your bed is of a non-standard size, consider a custom-size bunkie board for optimal support.
