Layer Details
Cover
A stretch-knit, soft-touch cover with a 100% Egyptian cotton white border. The stretch in the knit means the surface flexes with the fillings beneath rather than creating a drum-tight feel.
Comfort Layer
Deep layers of polyester comfort fillings, described as Soft White Fibres. These give the mattress its cushioned initial feel before you reach the springs.
Support System
1000 individual pocket springs, each encased in its own cloth pocket. Because every spring compresses independently, heavier areas like hips sink slightly more while lighter areas stay supported.

Key benefits
- 90cm each for two sharing: That's the width of a UK single per person, so a restless partner turning over happens a long way from your side of the bed.
- Distance plus pocket springs: Each of the 1000 springs compresses independently, and at this width your partner's movement has to cross a lot of independently sprung surface before it reaches you.
- Space for night-time visitors: When a child pads in at 3am, a super king means everyone keeps a workable share rather than one adult clinging to the edge.
- Medium firm feel across a big surface: The medium firm rating suits most sleeping positions, useful when two people with different preferences are choosing one very large mattress together.
- Fills a larger master properly: In a big period bedroom or a generous new build master, a UK king can look undersized; the extra 30cm of width sits in proportion.
This size suits you if...
You share the bed every night and want the maximum standard space UK retailers sell, your children or the dog regularly join you and a UK king has started feeling crowded, or one of you is a genuinely restless sleeper and you've realised distance solves what comfort layers can't. Allow at least 3m x 2.9m of bedroom, ideally more, so you can still move around it.
Consider another size if...
Your bedroom is smaller than the 3m x 2.9m we suggest, or you'd struggle to get a 180cm-wide mattress round your landing. We'd recommend the UK king instead: it's 30cm narrower, the same length, and needs at least 2.7m x 2.9m.

FAQ's
What room size do I need for a super king Classic Gold 1000?
We suggest at least 3m x 2.9m, and around 3.5m x 3.2m feels comfortable, leaving space to walk round both sides and open wardrobe doors. This is our own guidance rather than the brand's. If your room falls short, the UK king needs at least 2.7m x 2.9m and gives up only 30cm of width.
Is the Classic Gold 1000 super king good for couples with kids climbing in?
It's one of the better budget options for that. At 180cm wide there's 90cm each for two adults, so a small visitor at night still leaves everyone a usable share. The pocket springs help too: each one moves independently, so a wriggling child disturbs the surface locally rather than rocking the whole bed.
Will a super king mattress get up my stairs?
At 180 x 200cm it's the trickiest standard size to move, so measure your staircase, landing turns and door swings before ordering. Pocket spring mattresses flex less than all-foam ones, which makes tight turns harder. If access is genuinely awkward, the UK king is 30cm narrower and noticeably easier to manoeuvre.
How much space does each person get on this super king?
90cm each for two people sharing, which matches the width of a whole UK single per person. Compare that with the UK double, which the super king beats by 45cm of width, and you can see why restless couples size up: at this width, your partner's movement mostly stays on their side.
Does the medium firm feel change in the larger size?
No, the build is the same at every size: 1000 pocket springs under polyester comfort fillings, rated medium firm. What changes is how you experience it as a couple. With 90cm each, two sleepers of different weights each get support that follows their own shape, since the springs under one person compress independently of the other side.
