Layer Details
Top upholstery
Layered British fleece wool and cotton with bamboo, which gives exceptional softness directly beneath you. These natural fibres are highly breathable, so the surface stays temperate rather than trapping heat.
Support layer
Horsehair, a traditional filling prized for durability and resilience. It acts as a natural spring beneath the softer top layers, helping the mattress keep its shape over time.
Spring layer
Hand-nested calico pocket springs made from vanadium steel, with 1,720 springs in the 150 x 200cm size. It's a single layer of springs that move independently, which means support adapts to your body and you feel less of your partner's movement.
Base upholstery
Bonded British fleece wool and cotton with a built-in wool pad. This safeguards the mattress against wear from beneath, protecting the fillings where they meet the bedstead.

Key benefits
- 90cm each for two sharing: Two adults get 90cm each, which means a partner who turns over repeatedly is simply further away from you.
- Independent springs across a wide surface: The pocket springs move separately, so on a UK super king the space and the construction both help keep one sleeper's movement from reaching the other.
- Room for small visitors: When a child arrives at 3am or the dog settles at your feet, a UK super king leaves the adults a usable share instead of a narrow strip each.
- Wider than the UK king, same length: The UK super king is 30cm wider than the UK king and the same length, so the gain is entirely sideways, where sharers need it.
- Scale for a large bedroom: In a period property or a generous master bedroom, the 6ft x 6ft 6in footprint sits in proportion where a smaller bed can look a little lost.
This size suits you if...
You share with a partner whose tossing and turning wakes you, your children or dogs join the bed often enough that it feels routine, and your bedroom comfortably clears our suggested minimum of 3m x 2.9m.
Consider another size if...
Your bedroom is tight for a 180cm wide bed or the landing turns are awkward. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for it.

FAQ's
How much bigger is the Vispring Imperial super king than the king?
The UK super king is 30cm wider than the UK king, and the two are the same length. For a couple, that works out at 15cm more space each, since the UK king gives 75cm per sleeper and the UK super king gives 90cm.
Is a Vispring Imperial UK super king big enough for two adults and a child?
Two adults get 90cm each on a UK super king, which leaves more room to absorb a small child than any other size of this mattress. It suits occasional night-time visits well. If a child sleeps in with you most nights, the width helps, although it will still feel shared.
What size bedroom do I need for a Vispring Imperial UK super king?
We suggest allowing at least 3m x 2.9m, with around 3.5m x 3.2m feeling right once you add bedside tables and walking space. In a loft conversion, check which wall gives full head height along the 180cm width before you commit.
How many springs are in the Vispring Imperial super king?
Vispring publishes a count of 1,720 springs for the 150 x 200cm size, but doesn't give a figure for the UK super king here. Check the brand's own specification for the 180 x 200cm version if spring count matters to you.
What bed frame does a Vispring Imperial UK super king need?
The Imperial is designed for bedsteads, so you need a bedstead built for a 180 x 200cm mattress. Its bonded wool base upholstery is there to protect the fillings where they meet the frame, which is why a divan base is the wrong match.
