The Forever Foundation is a super strong metal platform bed foundation, which replaces the old fashion box spring and the metal bed frame. They last 8-10 times longer than the conventional foundation; provide 13" of under-bed storage space and works with all mattress types. Forever Foundations also help prevent bed bugs, dust, mildew, and allergens from collecting on the mattress. They are a snap to clean, recyclable, KD, and easy to assemble. Just put your dust ruffle over the foundation, place your mattress on top, and that’s it…done!
