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.
Layer details from emma-sleep.co.uk product page, September 2026.
- Real space for one: At 120cm wide, the UK small double is 30cm wider than the UK single, which means a solo sleeper can starfish rather than lie to attention.
- Fits where a double won't: It's 15cm narrower than the UK double, often the difference between a door that clears the bed and one that doesn't in a box room or studio.
- Zoned support at any width: The 7-zone Pro spring system gives your hips and shoulders different levels of give, so a solo sleeper gets the full alignment benefit across the whole surface.
- Cooler in a small room: Compact bedrooms can run warm, and the graphite-infused ThermoSync® foam draws heat away, a sensible pairing for this size.
- Copes with the odd shared night: The comfort foam edge improves support near the sides, useful when a visiting couple pushes a 120cm mattress to its limits.
- Easy to find bedding for: 4ft is a standard UK size, so small double fitted sheets and frames are widely stocked rather than a specialist hunt.
This size suits you if...
You sleep alone and have outgrown a single but your room can't spare the floor space a full double demands, you're furnishing a loft conversion or box room where every centimetre of walkway matters, or you're setting up a guest room that hosts couples a few weekends a year rather than every night.
Consider another size if...
You share the bed every night and 120cm feels like a compromise, or your room comfortably clears our suggested 2.4m x 2.8m minimum with room over. We'd recommend the UK double instead for nightly couples.

Is a small double Emma Original Pro big enough for a couple?
For occasional nights, yes. Across a 120cm width two adults will sleep close together, and the comfort foam edge on the Pro spring system helps when you're pushed towards the sides. For nightly sharing most couples find it tight, and we'd point you to the UK double or UK king pages instead.
What room size do you need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That gives you space to walk around the bed and open drawers or a wardrobe. In a loft conversion or box room, measure where the sloping ceiling or door swing sits before you commit, because the 120cm width is usually the deciding factor.
How much bigger is a small double than a single?
The UK small double is 30cm wider than the UK single, with both sharing the same 190cm length. That extra width is what makes it appealing for a teenager who's outgrown a single, or any solo adult who likes to spread out, in a room that can't take a 135cm double.
Does the Emma Original Pro feel different in the small double size?
The feel is the same medium firm hybrid you'd get in any size, with foam comfort layers over 7-zone pocket springs. What changes is who it works for: at 120cm wide it's generous for one sleeper, who gets the full zoned surface to themselves, and snug for two.
