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.

- Fits where space is tight: At 90cm wide, it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or two beds with a walkway between for siblings sharing.
- Washable cover suits kids: The cover zips off and machine washes at 40°C, which means spills and accidents in a child's bed are a laundry job rather than a disaster.
- Works on raised frames: At 25cm deep it sits within the guard rail limits of most bunk, cabin and mid-sleeper frames, though check your frame's stated maximum before buying.
- A mattress that lasts through teenage years: The medium firm feel and zoned springs support a growing teenager as well as an adult, so there's no need to upgrade as they get heavier.
- Guest ready without dominating the room: In a spare room that doubles as an office, the UK single gives visitors proper pressure-relieving comfort a few nights a year while keeping your desk usable the rest.
This size suits you if...
You're buying for a child or teenager, kitting out a bunk or mid-sleeper, or you sleep alone in a compact room such as a student flat or a loft conversion where only a narrow footprint fits under the slope. It also suits a spare room set up with two separate beds rather than one large one.
Consider another size if...
You're an adult who spreads out at night, or you want space for a partner to stay occasionally. The Emma Original Classic in a UK small double gives you an extra 30cm of width for solo comfort.

Will the Emma Original Classic UK single fit a bunk bed?
In most cases, yes. The UK single's 90 x 190cm footprint matches standard UK bunk, cabin and mid-sleeper frames, and its 25cm depth sits within the guard rail limit on most of them. Frames vary, so check the maximum mattress depth your frame allows; the rail needs to sit well above the sleep surface.
What room size do I need for the Emma Original Classic UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you room to walk alongside the bed and open drawers or wardrobe doors. In a child's room it usually leaves enough space for a desk and storage too, which is a large part of why the UK single remains the default kids' size.
Is the Emma Original Classic UK single good for a child or teenager?
Yes, with one caveat. The medium firm feel and 5-zone spring system support a growing body well, and the cover machine washes at 40°C, which is genuinely useful with younger children. Very light kids may find it slightly firm at first, but it's a mattress they can keep through their teens rather than outgrow.
Is a single Emma Original Classic big enough for an adult?
For one adult who sleeps fairly still, yes. At 90cm wide and 190cm long it's the standard UK one-person size, and the foam layers work the same as in the larger sizes. Taller adults or restless sleepers may feel hemmed in; the comfort foam edge helps you use the full width without feeling like you'll roll off.
How much narrower is the UK single than the small double?
The UK single is 30cm narrower than the UK small double, at 90cm wide against 120cm. Both are one-person sizes for this mattress, so the choice comes down to your room. If the extra width fits your floor plan, the UK small double is the more comfortable solo option; the UK single wins where space is tight.
