Layer Details
Emma cover
A cover that's gentle on your skin and completely removable. It machine washes at 40°C, which means keeping the sleep surface fresh is genuinely easy.
MemoryAdapt Foam
This enhanced foam moulds to your body's unique shape and distributes your weight evenly. In practice, that eases pressure points and keeps you comfortably supported.
Soft foam layer
An upgraded soft foam that gently adapts to your body from the very first moment. It helps ease pressure points and makes it easier to settle into a comfortable position.
SupportBase
SupportBase cushions your body and eases strain on sensitive pressure points. It also creates a smooth transition to the core layers, so you shouldn't feel any abrupt change in firmness as you sink in.
Spring system
The springs are divided into 5 targeted zones that adapt to you head-to-toe. A new comfort foam edge improves support towards the sides of the mattress.
Bottom cover
This layer anchors the mattress and grips your bed frame. That means less sliding about when you change the sheets or shift position at night.
Layer details from emma-sleep.co.uk product page, September 2026.
- Real space for one: At 120cm across, you get 30cm more width than a UK single, which means you can starfish, roll and shift position without meeting the edge.
- Fits where a double won't: Being 15cm narrower than a UK double, this size can be the deciding factor in a box room, loft conversion or studio where every centimetre beside the bed matters.
- Supported edge to edge: The comfort foam edge means the sides stay usable, which matters more at 120cm wide when you're likely to use the full surface.
- Copes with occasional sharing: The 5-zone spring system supports two different body shapes independently, so a couple staying a few weekends a year will sleep comfortably enough.
- Easy bedding to find: 4ft is a standard UK size, so small double fitted sheets and frames are widely stocked, and a standard double duvet drapes generously.
This size suits you if...
You sleep alone and have outgrown a UK single but can't spare the floor space a full UK double demands, or you're furnishing a guest room or rental second bedroom where couples stay occasionally rather than nightly. It also suits a teenager moving up from a single in a room that still needs space for a desk and wardrobe.
Consider another size if...
You share the bed every night, in which case 120cm feels tight for two adults over time. We'd recommend the UK double instead, or the UK king if your room allows at least a 150cm-wide bed.

Is the Emma Original small double big enough for two people?
For occasional nights, yes. The 5-zone springs and MemoryAdapt Foam support two sleepers independently, and the comfort foam edge keeps the outer 120cm usable. For a couple sharing every night, though, it's a squeeze, and the UK double or UK king of this mattress would be the better long-term buy.
What size room do I need for a small double mattress?
We suggest allowing at least 2.4m x 2.8m. That leaves enough space to walk around the bed and open drawers or a wardrobe. It's noticeably less than a UK double needs, which is exactly why this size works in box rooms, loft conversions and studio flats.
What are the dimensions of the Emma Original Classic small double?
It measures 120 x 190cm, or 4ft x 6ft 3in. That's 30cm wider than the UK single and 15cm narrower than the UK double, with the same 190cm length as both. The mattress itself is 25cm deep, so factor that into your frame and bedding choices.
Is a small double good for one adult?
It's arguably the ideal solo size. You get 30cm more width than a UK single, which means genuine room to spread out, and the medium firm foam eases pressure on hips and shoulders wherever you end up across the surface. If you like to sprawl but your room is modest, this is the size to pick.
Does the small double Emma Original suit a guest room?
Yes, it's a sensible guest room choice. It handles a visiting couple for a weekend, gives a solo guest plenty of space, and leaves more of the room free than a UK double would. The removable cover washes at 40°C, useful between guests. Compare the retailers listed on this page for current pricing.
