Emma Diamond Hybrid Deluxe Mattress
The Emma Diamond Hybrid Deluxe is a 29 cm deep hybrid, meaning it pairs foam comfort layers with AeroFlex pocket springs, which you'll feel as a balance of cushioning and support rather than the sink of an all-foam bed.
- Graphite foam draws heat away
- Snuggle in without sinking down
- Even support without dipping

The Emma Diamond Hybrid Deluxe is listed by Furniture Village as Medium in firmness, so it suits most sleepers, although anyone wanting a firm, on-top-of-the-bed feel should look elsewhere. Cooling is the headline here: a PolarLuxe cover and graphite-infused Diamond Cool foam are designed to pull heat away from you. It sits at the pricier end for Emma, but the depth and layer count go some way to justifying it.

Why should you choose this mattress?
Choose this mattress if you sleep warm and want a softer-leaning hybrid. The graphite particles in the Diamond Cool foam layer conduct heat away from your body, which means you're less likely to wake up clammy in summer. Underneath, pocket springs distribute your weight evenly, so heavier areas like hips get support without the whole mattress dipping. Buying through Furniture Village, you get a 200-night trial listed, plus delivery in 7 days with a paid Premium Delivery Service for mattresses, though do note those are Furniture Village's own terms rather than Emma's, so check whichever retailer you buy from. It comes in UK Single through to Super King.
Key features & layer details
PolarLuxe™ ultra cooling cover
An ultra cooling cover that feels instantly cool and refreshing when you first lie down. It's the first line of defence for hot sleepers.
Diamond Cool™ foam layer
Visco-elastic foam infused with graphite particles, which conduct excess heat away from your body. In practice, that means less of the heat build-up memory foam is known for.
HRXComfort™ foam layer
A comfort foam that lets you snuggle in without sinking down. You get cushioning at the surface while staying reasonably easy to move around on.
AeroFlex™ pocket springs
Individually pocketed springs that distribute your weight evenly, giving balanced support with pressure relief. They also add the responsiveness that all-foam mattresses can lack.
HRXSupport™ foam layer
A precision-engineered base foam that Emma guarantees will keep its shape for 10 years. This is what stops the mattress sagging over time.
Anti-slip bottom cover
A grippy underside that keeps the mattress in place on your bed frame all night. A small detail, but useful on slatted or divan bases.

Best suited for?
Warm sleepers
The PolarLuxe cover and graphite-infused Diamond Cool foam are designed to draw heat away from you, which means less clamminess on warm nights.
Couples
Individually pocketed AeroFlex springs spread weight evenly, so each partner gets balanced support without one person's movement dragging the whole mattress down.
Side sleepers
A softer-leaning feel with a HRXComfort foam layer lets you settle in without sinking too far, giving cushioning where shoulders and hips press in.
Combination sleepers
The pocket springs add responsiveness that all-foam mattresses can lack, so changing position during the night feels easier and you are not stuck in the mattress.
Adjustable beds
Pocket springs sit between layers of foam, and the anti-slip bottom cover keeps the mattress in place on the base as it moves.
If you prefer a firm mattress, or you're a heavier sleeper who needs a more supportive surface, this Medium feel may let you settle in further than you'd like. It's also a higher-priced option, so budget shoppers or anyone happy with a simpler all-foam design could spend less elsewhere.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
Is the Emma Diamond Hybrid Deluxe good for hot sleepers?
It's built with heat in mind. The PolarLuxe cover feels instantly cooling, and the Diamond Cool foam layer uses graphite particles to move excess heat away from your body, which means you should feel noticeably less warm than on a standard memory foam mattress.
How firm is the Emma Diamond Hybrid Deluxe?
The Furniture Village listing describes it as Medium. That suits most sleeping positions, particularly side and combination sleepers, although if you prefer a very firm surface, you may find it a little too yielding.
Does the Emma Diamond Hybrid Deluxe come with a trial?
Furniture Village lists a 200-night trial with this mattress. That trial is the retailer's own offer rather than a guaranteed Emma term, so if you buy elsewhere, check that retailer's trial and returns policy before ordering.
How deep is the Emma Diamond Hybrid Deluxe mattress?
It's 29 cm deep, which is on the taller side. Six layers make up that height, from the cooling cover down to an anti-slip base, so it's worth checking your fitted sheets will stretch over it.
What sizes does the Emma Diamond Hybrid Deluxe come in?
It's available in UK Single, UK Double, UK King and UK Super King.
