Layer Details
- Upholstery. Every filling is natural: British fleece wool, hand-teased horsetail blended with real Shetland wool, silk and mohair, plus blended Shetland wool and cotton, all encased in high-quality ticking. In practice that means a breathable, temperature-regulating surface that softens with body shape rather than trapping heat the way foam can.
- Springs. Two layers of hand-nested calico pocket springs made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Nesting the springs by hand in calico pockets lets each one move independently, which you feel as support that follows your shape closely.
- Borders. The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. This stiffens the edges, so the mattress holds its shape over time and supports you when you sit or sleep near the side.

- Room to move in a small bedroom: At 90cm wide the UK single leaves space for a desk or wardrobe, which means a spare room can still work as a study on the days nobody stays.
- Soft without sagging at the sides: The hand side-stitched borders keep the edges firm, so on a narrow UK single you can use the full width without feeling you might roll off.
- Cooler for warm solo sleepers: Wool and horsetail fillings let air move through the mattress, so a single sleeper who runs hot is less likely to wake up clammy under a loft ceiling.
- Pairs neatly for twin guest rooms: Two UK singles side by side give guests a bed each, and the soft tension feels cushioned for visitors who are unused to a firmer bed.
- A narrow footprint for sloping ceilings: In a loft conversion the UK single can tuck under the lower part of the roof, keeping the taller floor area free for standing and dressing.
This size suits you if...
You sleep alone, are light to average in build and like a soft, enveloping feel, or you are furnishing a compact guest room or loft bedroom where a narrow bed leaves the rest of the floor usable.
Consider another size if...
You share the bed, or you want more space to spread out on your own. We'd recommend the UK double instead, which gives 67.5cm each for two sharing; allow at least 2.6m x 2.8m.

Is the Vispring Sublime Superb UK single a sensible choice for a child?
It can be, but it is a lot of mattress for a growing child. The Soft tension suits lighter bodies well, although children often move beds within a few years, so the UK single makes more sense for an older teen staying put, or for an adult guest room.
Will the Vispring Sublime Superb UK single fit a mid sleeper or cabin bed?
Check the frame first. The mattress is 23cm deep with around 6cm of doming on top, and raised frames usually set a maximum mattress depth for the safety rail. Compare those figures with the frame maker's guidance before buying for a bunk, cabin or mid sleeper.
Is a UK single Vispring long enough for a tall adult?
The UK single is 190cm long, the same length as the UK double. If you are tall and your feet reach the end, the UK king is 10cm longer, although it is also much wider and needs at least 2.7m x 2.9m of floor space.
What size room do I need for a Vispring UK single?
We suggest allowing at least 2.1m x 2.8m. That leaves space to walk round the bed and open drawers, which matters in a child's room or a spare room that also holds a desk and wardrobe.
Should I buy two UK singles or one UK double for a guest room?
Two UK singles give friends or siblings a bed each, and each one keeps the soft, independent spring feel. A single UK double suits couples visiting, giving 67.5cm each, and needs at least 2.6m x 2.8m. Think about who usually stays with you.
