Construction & Materials

Emma Diamond Hybrid
Sleep Republic
Diamond Degree® Graphite Foam, Adaptive comfort foam, Pocket springs, HRX foam
Gel Infused Memory Foam, Natural Latex, High Definition Pocket Spring
Climate-regulating and elastic cover - This fully breathable, removable, and washable premium cover is designed to help facilitate heat dissipation of the Diamond Degree graphite foam. Its airy structure lets the mattress breathe during the day without hindering the thermoregulatory effects of the mattress.
Cashmere Knitted Fabric - We selected Cashmere fabric for the mattress surface material because we wanted a natural fabric that was soft to the touch, yet remained extremely durable.
Diamond Degree® graphite foam - With the infusion of diamond and graphite particles, this innovative coating quickly dissipates excess heat away; extending the duration of your deep sleep phase. The low rolling-resistance of the foam also requires less effort from your body when you involuntarily toss and turn during sleep, meaning you’re less likely to wake yourself up or be disturbed by your partner in the middle of the night. Adaptive comfort foam - This ergonomically designed foam layer adapts to your body and optimally distributes body pressure, allowing you to sleep comfortably regardless of your build or sleeping position (back, side, stomach).
3D Spacer Fabric - Our side panels are designed to let air circulate throughout your mattress. Mattresses need to breathe too you know! A top layer of Gel Infused Memory Foam for temperature stability. For the second layer, we chose Natural and renewable Latex, designed to breathe freely yet support uniformly.
Pocket springs - The individually encased steel pocket springs provide dynamic body adaptation and improved breathability over a standard foam mattress, while also allowing for movement isolation to minimize disturbances brought about by movements. HRX foam - This supportive foam layer provides optimal 3 zone back support and superb durability.
Dynamic Edge Support - Made of firmer high tensile steel springs, the edge support surrounds the mattress and allows full use of the total surface and for sleeper to lie up to the edge without roll-off. Memory foam for the ultimate in pressure relief and body contouring. Individual pocket springs mean no partner disturbance and a stronger mattress for a longer product life. Specifically zoned in 5 places to provide maximum support.
