The Magniflex KD Foundation is a knock-down bed foundation built on a 14-slat wooden frame system, designed for tool-free assembly and reliable breathability under any mattress, backed by Magniflex's 5-Year Warranty.
Please note: this foundation is only available for purchase alongside a matching Magniflex mattress — it is not sold as a standalone item. Add it directly from any Magniflex mattress listing using the "Add a Matching Magniflex Foundation" option.
A Simple, Solid Base
The KD (knock-down) Foundation is Magniflex's straightforward bed foundation: a 14-slat wooden frame that supports your mattress evenly and lets air circulate underneath it, rather than a solid, sealed platform. It ships flat and assembles without tools, so it's easy to move and set up in any bedroom.
At 8 inches high, it sits low and flush under a mattress, and it's available in Black, Brown, or Grey to match your frame or headboard.

Magniflex backs the KD Foundation with a flat 5-Year Warranty, so your foundation is protected for years of everyday use.
Airflow
14-Slat Breathability System
Fourteen wooden slats support your mattress across its full surface while leaving room for air to circulate underneath — better breathability than a solid platform base.
