Crate & Barrel Bunkie Boards

Even with a platform bed, some mattresses—especially memory foam or latex models—require a completely solid surface to prevent sagging between slats. A bunkie board creates that continuous, flat foundation, which helps maintain your mattress's structural integrity and warranty.

These boards are designed with a low-profile 2-inch height. They provide the necessary support for your mattress without significantly raising the overall profile of your bed.

A split king bunkie board is specifically designed for split king mattresses, which consist of two separate twin XL mattresses. Using two separate boards allows each side of the bed to be moved or adjusted independently if you have an adjustable base or simply prefer the ease of handling two smaller pieces.

Yes, these are compatible with most mattress types, including memory foam, latex, and hybrid mattresses. They are particularly beneficial for foam mattresses that need a solid base to prevent the material from dipping into the gaps of a slatted frame.

Yes, this bunkie board serves as a modern, low-profile alternative to a traditional box spring. It provides the same solid support for your mattress but without the extra bulk and height.
