The Emma Diamond Hybrid Deluxe Mattress blends cutting-edge cooling technology with responsive hybrid support to deliver your best night’s sleep.

At the surface, the PolarLuxe™ Cover offers cool-to-the-touch comfort and exceptional breathability, regulating your temperature from dusk till dawn.
Beneath it, Diamond Cool Foam infused with graphite particles actively dissipates heat, while the HRX Comfort Foam layer relieves pressure points and keeps your body perfectly cushioned.

At its core, AeroFlex® Springs provide adaptive, full-body support — individually encased to move with you and maintain natural spinal alignment. A final layer of HRX Support Foam reinforces structure, durability, and edge stability for long-lasting comfort.

The result? A premium hybrid mattress that delivers the ideal mix of support, softness, and cooling for deep, uninterrupted sleep — night after night.
