With the Emma Essential Mattress, you can finally grab a truly supportive sleep. The supportive HRX foam base has innovative zoning cutouts that provide advanced support to your shoulders and hips. Pressure through the body is distributed across the durable foam which allows for soothing spinal alignment and pressure relief. The plush top layer of memory foam has an open-pored cell structure that actively cools you down as you sleep. This innovative layer dispels heat and wicks away moisture allowing air to circulate more freely. It is topped off with a temperature regulating cover that is removable and washable so you can get the long-lasting freshness again and again.
