Layer Details
Premium cover
A thicker fabric layer that is soft to the touch, which means a more cushioned first impression when you lie down. It is 100% removable and machine washable at 40°C, so keeping it fresh is straightforward.
ThermoSync® foam
Graphite-infused foam that draws excess heat away from your body. In practice this means a more balanced, comfortable temperature through the night, useful if you tend to overheat.
MemoryAdapt Foam
This layer moulds to your body's shape and distributes weight evenly, which means less pressure building up at your hips and shoulders. You should feel gently cradled rather than perched on top.
Soft foam layer
An upgraded soft layer that adapts to your body from the first moment. It eases pressure points and makes it easier to settle into a comfortable position quickly.
SupportBase
This transitional layer cushions the body and smooths the change from soft comfort layers to the firmer core. The result is balanced firmness that supports you without letting you sink too far.
Pro spring system
Pocket springs arranged in 7 targeted zones that adapt to you from head to toe, which means firmer support where you carry more weight. A new comfort foam edge improves support when you sit or sleep near the sides.
Bottom cover
A grippy base fabric that holds the mattress steady on your bed frame. It stops the mattress shifting about, night after night.

Key benefits
- Proper space for two: At 75cm each for two people sharing, you can both change position freely, which means fewer elbows and less negotiating in the night.
- Less partner disturbance: The Pro spring system uses individual pocket springs, which means movement on one side is absorbed rather than transferred, useful if one of you gets up hours earlier.
- Extra length for taller sleepers: At 200cm long, the UK king adds welcome legroom, so a partner over six foot no longer sleeps with their feet at the edge.
- Usable edges across the full width: The comfort foam edge holds firm when you sit or sleep near the sides, which means both sleepers can spread out to the border without rolling off.
- Cooler sharing: Two bodies raise the temperature under a shared duvet, so the graphite-infused ThermoSync® foam drawing heat away matters slightly more in a couples' size like this.
This size suits you if...
You share the bed every night and a double has started to feel cramped, one of you keeps different hours and the other feels every movement, or one of you is approaching six foot and wants the extra length as much as the width. It also suits couples whose dog has quietly become a permanent third occupant.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m minimum we suggest for this size. In that case we'd recommend the UK double instead, which keeps space for two while fitting the room more comfortably.

FAQ's
Is the Emma Original Pro UK king big enough for two people?
Yes, comfortably for most couples. The UK king gives 75cm each for two people sharing, noticeably more personal space than a double, and the Pro's comfort foam edge means that width stays usable right to the sides. If you both like to sprawl, the UK super king is the roomier option.
Does the UK king Emma Original Pro stop me feeling my partner move?
It should help a good deal. The Pro spring system uses pocket springs that move independently, so one sleeper turning over transfers less motion across the bed, and the foam layers above dampen it further. Add the width of a UK king and an early riser can slip out with far less disturbance.
Is a UK king Emma Original Pro long enough for someone over six foot?
At 200cm, the UK king is 10cm longer than a UK double, which is often the difference between feet hanging over the end and a proper stretch. For anyone approaching or past six foot, that extra length is arguably a bigger upgrade than the width.
What size room do you need for this mattress in a UK king?
We suggest a room of at least 2.7m x 2.9m, with around 3.2m x 3.2m feeling comfortable. New build master bedrooms can be tighter than they first appear once wardrobes go in, so measure the floor space you'll actually have left before committing.
Should I get the Emma Original Pro in a UK king or UK super king?
The UK king is 30cm narrower than the UK super king, and for most couples it hits the balance between space and room demands. Go for the UK super king if your bedroom is generous and you regularly share with a child or a dog; otherwise the UK king is the sensible pick.
