Layer Details
Wool spring protector pad
A built-in wool pad sits over the springs to protect them. It helps the mattress last longer and keeps the springs from wearing through the fillings above.
Bonded British fleece wool and cotton
A bonded upholstery layer of British fleece wool and cotton (1,000gsm), with the wool Platinum Certified by the British Wool Marketing Board. It gives a natural, breathable cushion over the firmer layers below.
Long-stranded horsehair
A cambric-enclosed layer of long-stranded horsehair (1,200gsm) that is springy and resilient. It adds support and helps the mattress spring back into shape.
Bamboo
A bamboo fibre layer (200gsm) added for softness, absorbency and breathability. It helps draw moisture away from you, so the surface should feel fresher through the night.
Blended British fleece wool and cotton
The top layer is a blend of British fleece wool and cotton (1,200gsm) that adds loft and comfort. It gives you a soft, natural surface to lie on, with no foam in the mix.

Key benefits
- 90cm each for two sharing: Each of you gets 90cm of width, which means you can turn over or sprawl without landing in your partner's half.
- Distance plus independent springs: Pocket springs move separately, so a partner's tossing stays local, and the wider UK super king adds physical space on top of that.
- Room when the household joins you: If small children wander in at night or a big dog sleeps on the bed every evening, the extra width keeps everyone from ending up squashed at the edge.
- Suits a generous bedroom: In a large master or a high-ceilinged period room, the UK super king fills the space in proportion where a smaller bed can look a little lost.
- Full length for taller sleepers: At 200cm long, the UK super king matches the UK king for length and is 10cm longer than a UK double.
This size suits you if...
You share the bed with a partner who kicks, turns or gets up often, and you want real distance between you. It also suits you if children or pets regularly end up in the bed, or if your bedroom comfortably clears 3m x 2.9m and you want a bed that suits its size.
Consider another size if...
Your bedroom is tighter than our suggested 3m x 2.9m, or you usually sleep alone. We'd recommend the UK king instead, which needs at least 2.7m x 2.9m.

FAQ's
Vispring Imperial UK super king or UK king: which should I buy?
The UK super king is 30cm wider than the UK king and the same length. For two sharing, that is 90cm each rather than 75cm each, so 15cm more per person. The cost of that extra space is room: we suggest at least 3m x 2.9m for the UK super king and 2.7m x 2.9m for the UK king.
Is the Vispring Imperial UK super king big enough for two adults and a child?
It is the more comfortable of the two Imperial sizes for this. Two adults get 90cm each, compared with 75cm each on the UK king, so a small child who climbs in during the night has somewhere to go without anyone being pushed to the edge. An older child every night will still make it feel full.
How much space per person does a Vispring Imperial super king give?
For two people sharing, the Vispring Imperial super king gives 90cm each across a total width of 180cm. It is 200cm long, which is 6ft x 6ft 6in in imperial. That is 15cm more each than the UK king version of the same mattress.
Will a Vispring Imperial super king suit an older house or period bedroom?
In a large period room it tends to look right, because a smaller bed can seem undersized under high ceilings. Measure first: we suggest at least 3m x 2.9m, with around 3.5m x 3.2m feeling comfortable. Check how your bedroom door swings and whether tight landing turns will allow a mattress this wide through, as Vispring doesn't publish a weight for it.
Does a medium firm UK super king help if my partner is a restless sleeper?
It helps in two ways. The pocket springs respond individually, so movement on one side spreads less across the mattress, and the UK super king puts 90cm between each of you. Distance tends to matter more than any comfort layer with a genuinely restless partner. When ordering, confirm you have selected the medium firm tension specifically.
