Mattress Construction

Materials Overview

Take your sleep to the next level with the Emma Diamond Hybrid. The Emma Diamond Hybrid Mattress consists of four different layers:

  • Climate-Regulating and Elastic Cover
  • Diamond Degree® Graphite Foam
  • Adaptive Comfort Foam
  • Pocket Springs
  • HRX Foam.

Comfort Info

The excellent cooling and heat dissipation properties of the Diamond Hybrid mattress helps your body maintain the ideal sleeping temperature, enabling you to sleep longer in the deep sleep phase and feel more well rested when waking up.

Support Info

A hybrid mattress without compromise: the Diamond Hybrid mattress completely moulds to your body, thanks to its adaptive comfort foam and pocket spring construction.

Comfort Specs

Diamond Degree® Graphite Foam
This foam layer has an infusion of diamond and graphite particles, this innovative coating quickly dissipates excess heat away; extending the duration of your deep sleep phase.

Pocket Springs
Hundreds of individually encased steel pocket springs ensures superb ventilation by allowing air to circulate.

Support Specs

Diamond Degree® Graphite Foam
The low rolling-resistance of the Diamond Degree® graphite foam 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
The ergonomically designed adaptive comfort 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).

Pocket Springs
Individually encased steel pocket springs provide dynamic body adaptation, while also allowing for movement isolation to minimise disturbances brought about by movements.

HRX Foam
The supportive HRX foam layer provides optimal back support thanks to incisions in the foam and gives superb durability.

Fabric Specs

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. The top of the cover is made of 99% polyester and 1% elastane.

The bottom cover has convenient handles and is made of 87% polyester and 13% polypropylene, and the sides are made of 100% of polyester.
