Layer Details
Removable, washable top cover
A cover that unzips for washing, treated with Bugshield cover technology and OEKO-TEX 100-certified. That makes it easy to keep fresh.
Memory foam protector
A memory foam layer that allows the top cover to move freely while the first memory foam layer works independently. That means the cover and foam can each do their own job.
Premium-grade aurora foam
A high-density foam with an open cell structure for breathability and moisture evaporation. Its wave technology feels slightly firmer at the foot end, so you get zoned support as well as airflow.
Supporting foam layer
A second layer of high-grade supporting foam that adds depth and density for structure and stability. It also cushions pressure points.
2,000 pocket springs
The first layer of 2,000 springs in the 5,000 composite spring unit, which compresses first to support your contact points. That means the springs respond where you press down most.
1,000 nano springs
A layer of 1,000 super-soft nano springs that gives extra bounce. That means a bouncier feel underneath the foam.
2,000 more pocket springs
A further 2,000 pocket springs that complete the composite spring unit. They give the layers above a springy base to work from.
The support base
A high-density, environmentally responsible foam base that gives solidity to the layers above. It keeps the whole build stable.
Non-slip base
A base layer that keeps the mattress in place on the bed base. That means less chance of it shifting around.

Key benefits
- More room for each of you: At 75cm each for two sharing, the UK king gives 7.5cm more per person than a UK double, which means a little more distance between you and your partner every night.
- Length for a tall partner: The 200cm length (6ft 6in) is 10cm longer than a UK double, which means a partner approaching six foot can stretch out without their feet hanging off the end.
- Springs that respond where you press: The first layer of pocket springs compresses at your contact points, although the nano spring layer adds bounce, so a restless partner may still be felt slightly.
- Space for pillows and position changes: If you're pregnant or recovering and rely on extra pillows, the wider UK king leaves room for them without pushing your partner towards the edge.
- Standard king bedding: Ordinary king sheets fit, along with a 230 x 220cm king duvet, so you won't need to hunt for unusual sizes.
This size suits you if...
You share the bed every night and wake when your partner moves, or one of you gets up hours before the other. It also suits you if one partner is close to six foot and the end of a UK double has started to feel too close.
Consider another size if...
Your bedroom is under 2.7m x 2.9m once furniture is in, or you sleep alone. We'd recommend the UK double instead, which we suggest for rooms of at least 2.6m x 2.8m.

FAQ's
How much space do two people get on a Brook + Wilde Suprema UK king?
Each of you gets 75cm of width when sharing the 150cm UK king. That's 7.5cm more per person than the UK double, which gives 67.5cm each. It sounds small on paper, but it helps if one of you sprawls or you're often in bed at different times.
Is the Suprema UK king long enough for someone over six foot?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. If your partner is close to six foot and currently feels the end of the bed, that added length is often the bigger improvement than the width.
What size bedroom do I need for a Brook + Wilde Suprema UK king?
We suggest allowing at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. New build master bedrooms can feel tight once fitted wardrobes are in, so measure the floor space you'll actually have left and check you can still walk around both sides.
Should we get the Suprema in a UK king or a UK super king?
The UK super king gives 90cm each for two sharing, so the UK king gives 15cm less per person. Both are the same length. If you have a dog on the bed or a very restless partner, the UK super king helps, but we suggest at least 3m x 2.9m of room for it.
What bedding fits the Brook + Wilde Suprema in a UK king?
Standard king sheets fit, and a 230 x 220cm king duvet gives you both enough to tuck in. The mattress is 29cm deep, so check your fitted sheet's pocket depth suits that before buying.
