Layer Details
- Upholstery - Top Layer. British fleece wool, hand-teased horsetail blended with real Shetland wool, silk and mohair, plus a blend of Shetland wool and cotton, all encased in high-quality ticking. These natural fibres breathe and wick moisture, which means a cooler, drier sleep surface than most synthetic fillings.
- Springs. A two-layer, hand-nested calico pocket spring construction with 2,520 springs in the 150 x 200cm size, made from vanadium steel. Each spring moves independently, so you feel support tailored to your body rather than a single stiff platform.
- Borders. Upholstered with protective coir and wool, finished with four rows of hand side-stitching. This stiffens the perimeter, which means firmer edge support and less sagging where you sit or sleep near the side.

- 90cm each for two sharing: Sharing the UK super king gives each of you 90cm, which means a restless partner's turning happens well away from your side of the bed.
- All the extra space goes into width: The UK super king is 30cm wider than the UK king at the same length, so every added centimetre is width, which is where couples actually feel crowded.
- Room for late-night visitors: When a child wanders in or a large dog settles by your feet, the full 180cm width lets both adults keep a proper share of the mattress.
- Edges you can use across the whole width: The coir and wool borders with four rows of hand side-stitching keep the perimeter supportive, so the outer strips of this wide bed remain usable sleeping space.
- In proportion with a large bedroom: In a period property or generous master bedroom, a UK king can look slightly undersized, and the UK super king fills the space properly if you allow at least 3m x 2.9m.
This size suits you if...
You share with a genuinely restless partner and want distance rather than another comfort layer between you, children or pets regularly end up in the bed overnight, or your bedroom is large enough that a UK king would look a little lost in it.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or you mostly sleep alone. We'd recommend the UK king instead, for which we suggest at least 2.7m x 2.9m.

Is the Vispring Sublime Superb UK super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each on the UK super king, which is 15cm more each than the UK king offers. When a small child climbs in, that extra width is usually the difference between everyone sleeping and one adult hanging off the edge. The stitched coir and wool borders help here, as the outer edges stay supportive.
Vispring Sublime Superb UK super king or UK king: which should I choose?
The UK super king is 30cm wider than the UK king and the same length, giving 15cm more each for two sharing. Choose the UK super king if you share with a restless partner or regular visitors and your room allows at least 3m x 2.9m. If space is tighter, the UK king needs at least 2.7m x 2.9m.
Will I feel my partner move on a UK super king Vispring Sublime Superb?
Much less than on a narrower bed. The pocket springs move independently, so movement stays fairly local, and the UK super king adds distance on top with 90cm each. With a genuinely restless partner, that physical gap tends to matter more than any construction detail, which is the main reason to choose the UK super king over the UK king.
Can a UK super king Vispring Sublime Superb go in a loft conversion bedroom?
Often, but the ceiling slope usually dictates which wall the headboard can go against, so measure the full-height floor area rather than the total footprint. We suggest at least 3m x 2.9m for a UK super king, with around 3.5m x 3.2m feeling comfortable. If the usable space falls short, the UK king needs at least 2.7m x 2.9m.
Is the UK super king the largest Vispring Sublime Superb size?
Yes. This mattress comes in two sizes, the UK king and the UK super king, and at 180 x 200cm the UK super king is the larger. It is also the biggest mainstream UK size, so it takes standard super king bedding and a 260 x 220cm duvet. Compare the retailers listed on this page for current availability.
