Layer Details
Bonded British fleece wool and cotton
A layer of bonded British fleece wool and cotton sits closest to you. These natural fillings breathe well and help keep the sleep surface at a comfortable temperature.
Horsehair layer
Horsehair provides natural bounce and breathability. It springs back readily, which means the surface recovers quickly when you move rather than leaving an impression.
Blended British fleece wool and cotton
A further layer of blended British fleece wool and cotton adds cushioning above the springs. It helps distribute your weight evenly across the spring unit.
Spring system
The support comes from 1,476 vanadium steel pocket springs, hand-nested in calico and arranged in a single layer. Nesting the springs by hand packs them closely together, so support follows the shape of your body more precisely.

Key benefits
- More room each than a double: The UK king gives you 7.5cm more width each than a UK double, which means fewer nights spent perched on the edge to avoid an elbow.
- Quieter for early risers: Each pocket spring moves on its own, so if one of you is up hours before the other, getting out of bed should cause less disturbance.
- Length for a tall partner: At 200cm long, the UK king adds 10cm over a UK double, which is often the real reason a partner over six foot wants to upgrade.
- Firm support across a shared surface: The firm spring tension gives steady support to two bodies side by side, so a heavier partner is less likely to create a dip the lighter one rolls into.
- Fits more bedrooms than a super king: We suggest a room of at least 2.7m x 2.9m, so the UK king is realistic in a new build master bedroom once the wardrobes are fitted.
This size suits you if...
You share the bed every night and your UK double has started to feel tight, one of you is tall enough that feet hang off the end, or you keep different hours and want to disturb each other a little less.
Consider another size if...
You want considerably more than 75cm each, perhaps because a child or dog regularly joins you. We'd recommend the UK super king instead, which gives 90cm each and needs a room of at least 3m x 2.9m.

FAQ's
Is the Vispring Herald Superb UK king big enough for two people?
For most couples, yes. The UK king gives you 75cm each, which is 7.5cm more per person than a UK double. That extra width is modest on paper but noticeable in practice, particularly if one of you sleeps with arms out or shifts position often. If you regularly share with a child or pet, the UK super king would feel roomier.
Will I feel my partner moving on a Vispring Herald Superb king size?
Less than on many mattresses. The 1,476 springs are each pocketed and move independently, so movement stays closer to the person making it. Combined with 75cm of width each in the UK king, a partner getting up early or turning in the night should disturb you only slightly. A lighter sleeper beside a restless partner may still prefer the extra width of the UK super king.
Should I get the UK king or UK super king Vispring Herald Superb?
This mattress is only made in these two sizes. The UK king gives 75cm each and needs a room of at least 2.7m x 2.9m by our guidance. The UK super king is 30cm wider, gives 90cm each and needs at least 3m x 2.9m. Both are 200cm long, so choose on width and room space rather than length.
What size bedroom do I need for a Vispring Herald Superb UK king?
We suggest allowing at least 2.7m x 2.9m for a 150 x 200cm UK king, which leaves space to walk around the bed and open drawers. New build master bedrooms can feel smaller once fitted wardrobes are in, so measure the floor you actually have free rather than the room's full dimensions before ordering.
How much bigger is a king Vispring Herald Superb than my double?
The UK king is 15cm wider and 10cm longer than a UK double. By our guidance, a UK double needs a room of at least 2.6m x 2.8m, while the UK king needs at least 2.7m x 2.9m, so if your double fits with a little space to spare, the UK king will often fit too.
