Layer Details
Comfort Layer
Soft white synthetic fibres create a cosy feel on the surface. These are lightweight, high-loft materials, which means they should hold their height and shape over time rather than flattening quickly.
Support System
2000 extra firm pocket springs contour around your body shape while pushing back against it, which means full body support and spinal alignment rather than a hammock effect. This is where the very firm, sturdy feel comes from.
Edge Support
A wire rod runs along the perimeter of the pocket springs, giving you a durable edge that doesn't dip or sag. In practice, that means more usable sleep space right to the sides of the bed.

Key benefits
- 90cm of width each: Two sharers get 90cm each, which means a partner who tosses and turns is far enough away that distance does most of the work.
- Room for night-time visitors: When a child pads in at 3am, or a large dog treats the bed as theirs, 180cm of width means everyone still gets a workable share.
- Pocket springs keep movement local: The 2000 pocket springs compress individually, so someone shifting on their side of a bed this wide barely registers on yours.
- Usable edge to edge: A wire rod runs round the perimeter so the sides shouldn't dip, which matters when three of you are spread across the full 6ft.
- An extra firm feel that suits the space: Extra firm pushback keeps your spine aligned wherever you end up on the mattress, rather than rolling towards a partner in the middle.
This size suits you if...
You share every night and want maximum distance from a restless partner, children or pets regularly join you and a UK king has started to feel crowded, or you have a large master bedroom where anything smaller would look undersized. You'll also need to genuinely want an extra firm feel, because this mattress doesn't soften with size.
Consider another size if...
Your bedroom is under the 3m x 2.9m we suggest as a minimum, or the extra width would leave no walking space. The UK king is 30cm narrower, still gives 75cm each for two sharing, and we suggest at least 2.7m x 2.9m for it.

FAQ's
Is a super king too big for a normal bedroom?
Often, yes. We suggest at least 3m x 2.9m for a UK super king, and around 3.5m x 3.2m feels more comfortable once you add bedside tables and wardrobe doors. Check door swing and any landing turns too. If your room falls short, the UK king is 30cm narrower and needs at least 2.7m x 2.9m.
Is the Premium Gold 2000 super king good for couples with children who share the bed?
It suits that setup well. The 180cm width gives two adults 90cm each, so there's still a fair share when a child climbs in, and the extra firm springs stay supportive across the whole surface. Do check the child is happy on a very firm feel, because this mattress gives little cushioning.
How much wider is the super king than the king size?
The UK super king is 30cm wider than the UK king, and the two are the same length at 200cm. For two people sharing, that works out at 15cm more each: the UK king gives 75cm per person, the UK super king 90cm. If a restless partner is the reason you're upgrading, that extra distance is the point.
Will an extra firm super king mattress feel firm right to the edges?
It should. A wire rod runs around the perimeter of the 2000 pocket springs, which is designed to stop the sides dipping or sagging. On a bed this wide that matters more than usual, because sleepers, children and pets often end up spread right across it rather than clustered in the middle.
