Bunkie Board Foundation
A bunkie board is a thin platform commonly used to support a mattress in a daybed, platform bed, bunk bed, or trundle mattress. Bunkie boards provide adequate support in lieu of bulky box-springs. These supportive boards reduce the total height of the sleep set and are often used when space is an issue. The thinnest foundation possible, bunkie boards offer even lower foundational support than low-profile box-springs.
Bunkie boards have solid plywood or particle board cores and fabric coverings. The foundation is intended to go unnoticed, and upholstery usually features flat, muted colors. A bunkie board is the same length and width of the mattress it supports but only measures between one and a half and three inches tall.
