Not ideal for
PolarLuxe™ Cover
What it is: A premium cover crafted with advanced heat-conducting fibres that deliver an immediate cooling sensation upon contact with skin.
How it helps you sleep: Rapidly absorbs and dissipates heat to regulate temperature and maintain a consistently cool, fresh sleeping environment, preventing heat build-up for restful, uninterrupted sleep.
Diamond Cool™ Foam Layer
What it is: Emma's visco-elastic foam engineered with graphite particles that draw away excess heat to support natural temperature regulation.
How it helps you sleep: Promotes airflow and maintains a cool, comfortable sleep environment throughout the night by actively dispersing body heat away from the surface.
HRX Comfort Foam
What it is: Emma's High Resiliency Extra foam that provides sufficient counter-pressure to keep the spine evenly aligned.
How it helps you sleep: Designed to keep the spine in proper alignment in any sleeping position, promoting maximum relief, rest and recovery throughout the night.
AeroFlex™ Pocket Springs
What it is: Individually encased steel pocket springs made from high carbon steel, each moving independently to respond to body weight and movement.
How it helps you sleep: Provides adaptive, full-body support with excellent motion isolation, meaning you won't be disturbed when your partner moves - and the open structure promotes airflow through the mattress core.
HRX Support Foam Base
What it is: Emma's High Resiliency Extra support foam providing counter-pressure for consistent spinal alignment across all sleeping positions.
How it helps you sleep: Supports the spine in its natural position regardless of how you sleep, helping to alleviate pressure and reinforcing the long-term structure of the mattress for lasting performance.
Non-Slip Base
What it is: A specially designed anti-slip fabric on the underside of the mattress that anchors it firmly to the bed frame or base.
How it helps you sleep: Prevents the mattress from shifting during the night, ensuring it stays perfectly positioned so you enjoy uninterrupted, restful sleep.

Vs firmer mattresses: The medium feel gives noticeably more pressure relief at the shoulders and hips than firmer options, while still offering enough support for back and front sleepers. If you change position through the night, share a bed or run warm, this is likely the better fit. Firmer mattresses suit heavier sleepers or those who want a more rigid, orthopaedic-style surface.
Vs softer mattresses: The AeroFlex™ pocket spring core and HRX support foam give this mattress more structure than a softer option, helping it keep your spine aligned whether you sleep on your side, back or front. Softer mattresses can feel more immediately plush and may suit lightweight side sleepers who want a deeper sink, but they are less likely to maintain consistent support for back and front sleepers or couples with different body weights.
Vs premium and luxury mattresses: The Diamond Hybrid Deluxe shares the advanced cooling technology and individually wrapped pocket spring construction found in Emma's wider premium line. Where higher-priced mattresses may differ is in the depth of natural fillings or hand-finishing. What this mattress delivers is engineered, technology-led comfort at a price point that doesn't compromise on performance.
The Emma Diamond Hybrid Deluxe is backed by Emma's 10-year manufacturer's guarantee against defects in materials and workmanship. With OEKO-TEX® certified foam layers and a precision-engineered spring and foam construction, this is a mattress built to deliver consistent performance for the long term - and the guarantee reflects exactly that.
National Bed Federation (NBF) Approved - Independently verified to meet strict UK standards for quality, safety and responsible manufacturing.
OEKO-TEX® Standard 100 - Every foam layer in the Diamond Hybrid Deluxe carries OEKO-TEX® Standard 100 certification, confirming the materials are free from harmful substances and safe for skin contact.
The Emma Diamond Hybrid Deluxe brings together AeroFlex™ pocket springs, Diamond Cool™ graphite-infused foam and the PolarLuxe™ cooling cover in a medium feel that suits side, back, front and combination sleepers. If you run warm at night, share a bed or want a mattress that balances cushioning with dependable support, this is a well-rounded choice.
Choosing a mattress online takes trust. That's why the Emma Diamond Hybrid Deluxe comes with a 200 night comfort guarantee - if it doesn't feel right, we'll exchange it. View the full mattress trial policy.
