Bed support is essential for a restful sleep and a healthy back. There are many synonyms for bed support, including mattress support, foundation, box spring, bed base, platform bed, slatted bed, and bed frame. Mattress support refers to any device or material that helps keep a mattress in position and provides a stable foundation. A foundation is a strong support that holds a mattress in place, and a box spring is a type of foundation consisting of a sturdy wooden frame covered with fabric and springs.
