Layer Details
Natural fillings
Over 2,800g of natural fillings layered by hand, including South American horsetail, real Shetland wool, Mulberry silk and mohair. These materials breathe well and regulate temperature, which means less of the clammy warmth you can get with synthetic fillings.
Spring core
High-tensile vanadium steel springs, each one hand-nested and placed in a breathable cotton calico pocket. Individually pocketed springs respond to each sleeper separately, so you feel less movement from a partner turning over.
Spring insulator pad
An integrated insulator pad sits with the spring unit to keep support consistent. It means the mattress performs properly on either a slatted bedstead or a sprung base.

Key benefits
- A full 90cm each: Two people sharing get 90cm each, so a partner who tosses and turns has room to do it without ending up on your side.
- Room when the family arrives: When a child climbs in before dawn, the extra width means they fit between you rather than pushing one parent onto the edge.
- Less disturbance across a wide surface: Individually pocketed springs respond to each sleeper separately, which means you feel less of the movement when someone turns over at the far side.
- Cooler with extra bodies: Calico pockets and wool fillings let air pass through the mattress, which helps when a warm child or a large dog adds heat to the bed.
- Proportion in a large room: In a period property or a generous master bedroom, 180cm of width looks settled, where a UK king can look slightly undersized against the walls.
This size suits you if...
You share with a partner whose restlessness keeps waking you, or children and a large dog regularly end up in the bed. Your bedroom should also comfortably clear our suggested minimum of 3m x 2.9m.
Consider another size if...
Your room is smaller than our suggested 3m x 2.9m, or you rarely share the bed. We'd recommend the UK king instead, and we suggest at least 2.7m x 2.9m for that size.

FAQ's
Is the Vispring Heybrook super king big enough for two adults and a child?
For occasional visits, yes. Two adults get 90cm each in a UK super king, compared with 75cm each in a UK king, so a small child has a real gap to settle into. The firm surface also means a child is less likely to roll into the middle and wake you.
How much bigger is the Heybrook 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 each. The difference is all in width, so you gain side-to-side room, but taller sleepers get no extra legroom from sizing up.
Heybrook super king vs double: is the jump worth it?
For a couple, it's a big change. The UK super king is 45cm wider and 10cm longer than the UK double, and gives 22.5cm more each. Yes, it needs far more floor, but if a restless partner is the problem, distance does more than any comfort layer can.
Will a Vispring Heybrook super king work in a loft conversion bedroom?
Only if the room is big enough and has a full-height wall for the headboard. The slope usually decides where the bed goes, so measure the flat floor area, not the whole room. We suggest at least 3m x 2.9m for a UK super king, plus space to get in and out on both sides.
Can a large dog share a Heybrook super king comfortably?
It's one of the better setups for it. With 90cm each for two people, a dog lying across the foot takes far less of your space than on a narrower bed. The breathable calico springs and wool fillings help the mattress stay cooler with the extra body heat.
