Layer Details
Upholstery - Top Layer
British fleece wool sits alongside hand-teased horsetail blended with real Shetland wool, silk and mohair, plus a Shetland wool and cotton blend, all encased in high-quality ticking. These natural fibres wick moisture and breathe, which means a cooler, drier sleep surface than synthetic foams tend to give.
Springs
A two-layer construction of hand-nested calico pocket springs made from vanadium steel, with 2,520 springs in the 150 x 200cm size. Two layers working together means finer, more progressive support: gentle at first contact, firmer as you settle in.
Borders
The borders are upholstered with protective coir and wool and finished with four rows of hand side-stitching. This anchors the springs to the edge of the mattress, which means firmer edge support and less of that roll-off feeling when you sleep near the side.

Key benefits
- Real distance from a restless partner: Two people sharing get 90cm each, which means a partner who tosses and turns is far easier to sleep through than on any narrower bed.
- More room than the UK king: The UK super king gives 15cm more each than the UK king at the same length, so the gain goes entirely into width.
- Space when the family piles in: When a child wanders in at 3am or a large dog settles at your feet, the extra width means the adults still keep a usable share.
- Firm support across a wide surface: Independent pocket springs respond to each sleeper separately, which means heavier or back sleepers get stable support without feeling every shift from the other side.
- Usable right to the edges: Coir-reinforced, hand side-stitched borders keep the sides supportive, so you can use the full 180cm rather than drifting towards the middle.
- In proportion with a big bedroom: In a period property or large master bedroom, where a UK king can look slightly undersized, the UK super king fills the space properly.
This size suits you if...
You share with a genuinely restless partner and want proper distance between you, or your bed regularly fills up with children or a large dog by morning and you would like everyone to keep a fair share.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Vispring Sublime Superb Firm 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 disturbance or shared family nights are the problem. If your room is tight, the UK king needs at least 2.7m x 2.9m, against 3m x 2.9m for the UK super king.
Is a UK super king big enough for two adults and a child?
For occasional nights, usually yes. With 90cm each for two adults, a small child who climbs in can fit without anyone ending up on the edge. The reinforced borders help here, because the sides stay supportive rather than sagging. For a child who joins you every night, expect it to feel a little snug by morning.
Can a Vispring UK super king go in a loft conversion bedroom?
It can, but the sloping ceiling usually decides which wall the bed takes. Allow at least 3m x 2.9m of floor space, with around 3.5m x 3.2m feeling comfortable. Check headroom on the side where each of you gets in and out, as a low slope next to the bed quickly becomes annoying.
How much bigger is the Vispring super king than a UK double?
The UK super king is 45cm wider and 10cm longer than a UK double. For two people sharing, that works out at 22.5cm more each, which is a very noticeable step up if you are moving from a UK double and have been bumping elbows for years.
What extra costs come with a Vispring Sublime Superb in a UK super king?
Bedding is the one people forget. You will need super king sheets and a 260 x 220cm duvet, which usually cost more than UK king equivalents. For the mattress itself, compare the retailers listed on this page, where prices update as retailers change them.
