Built like a fortress, the Rock Arthur Mattress is all about ultra-firm support for those who prefer a harder sleep surface. Engineered with high-density foam and reinforced spring layers, it offers a sturdy, no-sink feel that’s perfect for back sleepers or anyone seeking serious spinal alignment. Despite its firm feel, Rock Arthur doesn't skimp on comfort. A quilted top layer adds a touch of softness, while the breathable construction ensures airflow all night long. It’s rock-solid support without the rough edges.
