PURPLE 9" QUEEN METAL PLATFORM provides a sturdy, low-profile foundation that supports a mattress without the need for a box spring. A welded metal frame finished with a durable polyurethane coating delivers stable support and resists everyday wear, while closely spaced slatted rails promote airflow to extend mattress life. At a nine-inch height, this platform balances a minimal footprint with practical support, ships made in the USA, and is engineered for straightforward assembly and long-term use.
