About the Blue Lagoon Nights Plush Mattress

Featuring an 825-coil density system, this supportive mattress offers zoned comfort and pressure relief with a lumbar gel support band and Cool Twist® Gel Memory Foam that contours to your body—with upgrades available with more cooling layers and support.


  • Cool Twist® Gel Memory Foam - This unique design features cooling gel swirled into premium memory foam. This breathable memory foam helps enhance airflow and heat dissipation for a feeling that can only be described as a cool, contouring type of comfort.
  • PillowSoft® Aire - Soft foam provides enhanced cushioning for exceptional comfort and promotes airflow through its unique, gently rippling design.
  • Gel Band Support - Gel memory foam lumbar support band provides support for the lower back and hips. 
  • Anti-Microbial Technology - Our anti-microbial mattress technology will keep your mattress fresh and clean from odor-causing bacteria.
  • Custom Support Coil System - This 825-coil density system provides contouring, cradling support and minimizes motion transfer.
  • Phase Change Material - Stay temperature-regulated with this technology, which absorbs body heat, and then releases it if you cool down too much. 
  • Best Edge® Foam Encasement - Added support for the edge makes it easier to sit down as well as get out of bed. It also makes the sleeping surface more stable and increases the durability of the mattress.
