Layer Details
BioFresh™ cover
The BioFresh™ cover, powered by HEiQ technology, continuously breaks up allergens. That means a fresher sleep surface, which is helpful if you're prone to sniffles or dust sensitivity.
FusionAir™ foam layer
The FusionAir™ foam layer's open cell construction encourages air circulation. In practice, heat can escape rather than gathering around you, so warm sleepers should find it a little more comfortable through the night.
HRXComfort™ foam layer
The HRXComfort™ foam layer lets you snuggle in without sinking down. You get that cushioned, hugged feeling on the surface while still being able to change position easily.
AeroFlex™ pocket springs
AeroFlex™ pocket springs distribute weight evenly for balanced support with pressure relief. Because each spring moves independently, heavier areas like your hips are supported without the whole surface dipping.
HRXSupport™ foam layer
The HRXSupport™ foam base is precision-engineered and guaranteed to keep its shape for 10 years. It anchors everything above it, which means the mattress should resist sagging over time.

Key benefits
- Springs that keep the peace: AeroFlex™ pocket springs move independently, so in a UK king a partner getting up hours before you causes far less ripple across the surface.
- 75cm each, every night: With 75cm each for two people sharing, you can enjoy the mattress's cushioned, hugged feel without drifting into each other's space.
- Length for taller sleepers: At 200cm long, anyone approaching 6ft gets proper foot room, which is often the real reason couples size up rather than the width.
- Cool across a wider surface: The FusionAir™ layer's open cell structure lets heat escape, useful on a shared bed where two bodies warm the mattress faster than one.
- Easy movement despite the soft feel: The HRXComfort™ layer lets you settle in without sinking, so changing position on this wider surface takes little effort even mid-pregnancy or after injury.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, especially with a medium soft mattress that invites you both to spread out. It also fits if one of you is over 6ft and wakes with feet hanging off a shorter bed, or if a dog has quietly claimed a strip of the mattress and you'd rather add width than argue.
Consider another size if...
Your bedroom measures less than our suggested 2.7m x 2.9m, which is tight once wardrobes go in. We'd recommend the UK double instead: it keeps the same layers and feel while leaving room to walk around the bed.

FAQ's
Is the Emma Helix Hybrid Deluxe UK king big enough for two people?
Yes, comfortably for most couples. The UK king measures 150 x 200cm, giving 75cm each for two people sharing, 15cm more width overall than a UK double. On a medium soft mattress like this one, that margin stops you rolling towards each other when one of you snuggles into the foam layers.
Will my partner getting up early disturb me on the UK king?
Less than on a smaller bed. The AeroFlex™ pocket springs respond individually rather than as one unit, so movement on one side transfers weakly to the other. Combine that with 75cm each for two people sharing and an early alarm on their side is far easier to sleep through.
Is a UK king long enough if I'm over 6ft?
At 200cm, or 5ft x 6ft 6in in imperial terms, the UK king suits most tall sleepers. For many couples the length is the quiet win of sizing up from a UK double, which is shorter. Only exceptionally tall sleepers tend to need more than 200cm.
What room size do I need for this mattress in a UK king?
We suggest a room of at least 2.7m x 2.9m, and around 3.2m x 3.2m feels genuinely comfortable. That guidance is ours, not Emma's. New build master bedrooms can be deceptive: they look generous empty, then wardrobes and bedside tables on both sides eat the walking space quickly.
