Your sleep trial begins the day your mattress is delivered, not when you place your order.
Emma Diamond is designed to give you your coolest, most comfortable sleep yet.
From the moment you lie down, the cool-to-touch antibacterial cover creates an instantly fresh feel, while graphite-infused ThermoSync foam helps pull heat away from your body throughout the night.
Plush memory foam layers gently relieve pressure, while a hybrid spring system keeps your body supported and aligned. And surrounding it all, a reinforced foam frame adds extra stability. So you can sit, sleep, and stretch out comfortably all the way to the edges.
Emma Diamond provides sleep that feels cooler, deeper, more supportive, and effortlessly comfortable. You can learn more about it below.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Engineered with high-density HRX foam, this layer reinforces the mattress structure, delivering exceptional durability, shape retention, and consistent support over time.
The bottom cover keeps your mattress perfectly positioned on the bed, all night, every night.
