Layer Details
- Comfort fillings. Layers of natural British wool, cotton, hemp and flax fibres sit at the sleep surface. One side places wool closer to the top for winter warmth, while the other includes moisture-wicking cotton for summer freshness, so you flip the mattress with the seasons.
- Mini Pocket Springs. A layer of 15,800 mini springs delivers bouncy comfort, with the small pockets creating airflow throughout the mattress. They reach areas that broader springs can miss, such as the hips and lower spine.
- Support System. At the base, 700 Cortec™ Quad springs are encased in cloth pockets and secured into groups of four. They're highly responsive, providing support based on your unique weight, shape and movement.

- A serious mattress for a solo sleeper: You get the same 15,800 mini pocket springs and 700 Cortec Quad springs as the larger sizes, all working for one person rather than two.
- Compact footprint, easy fit: At 90 x 190cm, it leaves floor space free for a desk, wardrobe or storage in a smaller bedroom, and we suggest allowing at least 2.1m x 2.8m.
- Natural fillings suit warm sleepers of any age: Wool, cotton, hemp and flax breathe better than foam, which means a teenager or adult who runs hot should sleep cooler through the summer.
- Seasonal flipping is manageable at this size: The dual-sided design needs turning twice a year, and a UK single is light enough for one person to flip without help.
- Cheap, widely stocked bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the easiest bedding sizes to find in the UK.
This size suits you if...
You're a solo adult or older teenager who wants a genuinely well-made mattress in a compact room, you sleep warm and prefer the buoyant feel of natural fibres and springs over foam, or you're furnishing a spare room that gets regular enough use to justify spending properly on it.
Consider another size if...
You share the bed, or you're an adult who feels hemmed in at 90cm wide. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest a room of at least 2.4m x 2.8m for it.

What are the dimensions of the Harrison Spinks Emerald 16500 in a UK single?
The UK single measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any standard single bed frame and takes standard single sheets and a 135 x 200cm single duvet.
Will the UK single Emerald 16500 fit a bunk bed or mid sleeper?
The width is right, but the depth may not be. This mattress is 29cm deep, and raised frames usually specify a maximum mattress depth so the safety rail still sits high enough above the sleep surface. Check your frame's stated limit before ordering, because most bunks are designed for much shallower mattresses.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves room to walk alongside the bed and open a wardrobe, which matters if the bedroom also has to hold a desk or storage. In a loft room with sloped ceilings, the single's narrow footprint is often the only size that works.
Is the UK single Emerald 16500 long enough for a tall adult?
It's 190cm long, the same length as the UK small double and UK double. If you're tall enough that your feet reach the end, the UK king is 10cm longer, although it's also 60cm wider, so it changes the room requirement considerably: we suggest at least 2.7m x 2.9m for the UK king.
