Comfortable Sleep from the First Night

The 12” BeautySleep® Coastline Quilted Mattress in a Box is crafted to provide exceptional comfort and support. Featuring a soft quilted surface and breathable foams, this mattress ensures airflow for a cool and refreshing sleep. Its antimicrobial layer* helps maintain freshness, while the Original Beautyrest® Pocketed Coil® Technology delivers consistent, reliable support.

Advanced Foam and Coil Technology

Experience the benefits of AllCool™ Gel Memory Foam, which contours to your body to relieve pressure, and AirCool® Foam with a channeled design for enhanced airflow. The 8" layer of Original Beautyrest® Pocketed Coil® Technology, combined with supportive base foam, offers stable and comfortable support throughout the night.

Firm or Plush Pillow-Top Options
