Layer Details
- Cover. A knit cover with breathable micro-dots that move air outwards, designed to feel cool and ultra soft. It's the first thing your skin meets, so the airflow focus should help if you tend to run warm.
- Emma AirGrid™ Tech. Emma's most advanced AirGrid™ layer, a flexible grid engineered to adapt to your body. In practice, this means pressure relief that adjusts to your shape rather than pushing back uniformly.
- MemoryAdapt layer. This gives the first comforting hug, responding to your body with immediate cushioning. It's where the pressure relief you feel at hips and shoulders comes from.
- SupportBase. A transition layer that keeps you supported in every zone, easing strain on sensitive pressure points. It also creates a smooth handover to the core layers, so you don't feel a sudden change in feel as you sink in.
- Zoned pocket springs. These add bounce, extra support and stability, with zoning to give responsive support where you need it. The pocketed design also reduces motion transfer, useful if you share the bed.
- SupportBase. A second SupportBase layer that grounds the zoned spring core and keeps the mattress structure stable. Think of it as the foundation everything else works from.
- Bottom cover. A simple base cover that keeps the mattress in place on your bed frame.

- Fits where other sizes can't: At 90cm wide, this mattress leaves floor space for a desk, wardrobe and toy storage in rooms where a UK double simply wouldn't go.
- Grown-up support for growing sleepers: The zoned pocket springs and MemoryAdapt layer support a teenager through years of growth, so this is a single that won't need replacing at sixth form.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm duvet fit, and they're the most widely stocked bedding of any UK size, though deep-pocket fitted sheets suit the 28cm build best.
- A comfortable guest option: Pressure relief from the AirGrid™ layer means visitors get a genuinely comfortable night, rather than the thin, forgettable mattress spare rooms often end up with.
- Works in awkward spaces: The narrow footprint suits loft conversions and box rooms where the bed has to tuck under a slope or along one wall.
This size suits you if...
You're buying for one sleeper, a child moving up from a cot bed, a teenager who needs proper support, or an adult in a compact room. It also suits a spare room that doubles as an office, where a UK single keeps the desk usable, or a first flat where the frame came with the room but the mattress didn't.
Consider another size if...
You're an adult who spreads out in the night, or you occasionally share the bed. The 90cm width is snug for restless solo sleepers, so we'd recommend the UK small double instead, which adds 30cm of width in the same 190cm length.

Is the Emma Performance 28 UK single suitable for a bunk bed?
Be careful here. The Emma Performance 28 is 28cm deep, which is taller than many bunk, cabin and mid-sleeper frames are designed for. On a top bunk especially, a deep mattress can sit above the safety rail. Measure from the base to the top of the rail before buying, and check the frame maker's maximum mattress depth.
What size is the Emma Performance 28 UK single?
It measures 90 x 190cm, or 3ft x 6ft 3in, the standard UK one-person size. Bear in mind the 28cm depth too: it changes how the bed looks and which fitted sheets will stretch over it, so deep-pocket single sheets are the safer buy.
Is the Emma Performance 28 single good for a child or teenager?
For a teenager, yes: the zoned pocket springs and memory foam give proper support through growth spurts, and a UK single fits most children's rooms comfortably. For younger children the 28cm height is the thing to weigh up, as it makes the bed noticeably taller to climb into on some frames.
Will a UK single Emma Performance 28 fit in a small bedroom?
In most cases, yes. We suggest allowing at least 2.1m x 2.8m of floor space, which leaves room to walk round and open drawers. That guidance is ours rather than Emma's. The 90cm width also suits loft rooms where the bed has to sit under the slope.
Does the Emma Performance 28 single work in a guest room?
It's a strong guest room choice, if a slightly indulgent one. The AirGrid™ and MemoryAdapt layers give visitors real pressure relief rather than a token spare bed, and the 90cm width means two singles plus a walkway can fit where one larger bed wouldn't.
