Upgrade your sleep sanctuary with the innovative comfort and support of Nautica Home’s Serenity 12-Inch Gel Memory Foam Medium Plush Mattress, including a removable, machine-washable zip-off cooling cover. Maintaining a soft, refreshing sleep surface, a layer of liquid gel-infused memory foam directly below the cover reduces pressure points and offers cooling relief. With advanced sleep technologies and an overall medium-plush feel, this cooling mattress in a box features traditional contouring memory foam over 3-inches of channel-vented liquid gel and engineered latex for high airflow and responsivity. The patented foam tray perimeter extends the sleep surface and reinforces the edges, while a ventilated high-density foam base enhances breathability and support.
