  • We invest into research

    Our proprietary research and product development lets us combine smart design with modern materials, so you get superior quality at affordable prices.

    Advanced 7-Zone Ergonomic Design

    Seven targeted zones work in harmony to support your body—from shoulders to lower back and beyond. Powered by Infinity Springs, this system adapts dynamically to your shape, delivering enhanced alignment, pressure relief, and undisturbed sleep.

    Instantly Cool, Effortlessly Fresh

    Engineered with a cool-to-touch finish, this premium cover provides immediate freshness and lasting comfort, delivering an instantly fresh sensation the moment you lie down. Its antibacterial properties help maintain a cleaner sleep surface over time.

    Sleep Through Every Movement

    Advanced motion isolation minimizes movement across the mattress, so you won’t feel a thing on the other side of the bed. Sleep deeply, without interruptions.

    Cooling That Adapts to You

    ThermoSync™ graphite-infused HyperSoft foam actively draws heat away from your body to help maintain an optimal sleep temperature. Its open-cell structure enhances airflow, while the responsive feel allows effortless movement—so you stay cool, comfortable, and undisturbed all night.

    Let's take a look under the covers

    • 1

      The antibacterial cover

      A cool-to-the-touch, antibacterial cover that feels fresh the moment you lie down. It is removable and machine washable, so your bed stays as clean as it is comfortable.

    • 2

      ThermoSync Foam

      Graphite-infused foam helps pull heat away from your body, keeping your temperature comfortable throughout the night. Its breathable, open-cell design promotes airflow, while the soft, responsive feel makes it easy to move without disturbing your sleep.

    • 3

      MemoryAdapt Foam

      Memory foam gently contours to your body, helping relieve pressure on areas like the shoulders and hips while supporting healthy spinal alignment. By distributing weight evenly, it creates a more comfortable, supported sleep and helps minimize motion transfer for fewer disturbances during the night.

    • 4

      Supportive HRX Foam

      A high-resilience foam layer that provides added stability and support, creating a smooth transition between the softer comfort layers and the supportive base. It helps prevent excessive sink while maintaining the mattress’s structure and performance over time.

    • 5

      7-Zone Pocket Springs

      Individually wrapped springs adapt to your body with targeted support across 7 zones, helping keep your spine aligned as you move throughout the night. This dynamic system also promotes airflow to reduce heat and moisture buildup, while minimizing motion transfer for a more undisturbed sleep. Surrounded by a supportive foam frame, it also provides enhanced edge stability.

    • 6

      HRX Durability Foam

      Engineered with high-density HRX foam, this layer reinforces the mattress structure, delivering exceptional durability, shape retention, and consistent support over time.

    • 7

      The layer that holds your mattress in place

      The bottom cover keeps your mattress perfectly positioned on the bed, all night, every night.
