Layer Details
- Cover. A breathable Belgian damask fabric cover, which means air can move through the sleep surface rather than trapping warmth against you. It's a traditional, hard-wearing choice.
- Comfort Fillings. Soft white fibre fillings made from 100% polyester. These give a gentle cushioned feel over the springs, though they're simpler than the foam layers found on pricier mattresses.
- Support System. 1,000 individually pocketed springs, each mounted in its own separate fabric pocket so they work completely independently of one another. In practice, that means support follows your body's contours and your partner's movements are less noticeable.
Layer details from mattressnextday.co.uk product page, September 2026.
- A full 90cm each: Two adults each get 90cm of width, which means a partner turning over sits further from you and you are far less likely to feel it.
- 15cm more each than a UK king: Against the UK king, the UK super king adds 15cm per sleeper, the difference between touching elbows and sleeping undisturbed.
- Room when the family piles in: When a small child climbs in during the night, the extra width means the adults can keep sleeping instead of clinging to the edges.
- Independent springs across a wide surface: The pocketed springs respond individually, so movement on one side travels less across the bed, which counts for more when the bed is shared with pets or children.
- Same length as the UK king: At 200cm long, the UK super king matches the UK king for legroom, so taller sleepers lose nothing by sizing up.
- Simple, supportive build at scale: You get traditional medium firm support across the whole sleeping area, although lighter side sleepers may find it slightly firm at the hips.
This size suits you if...
You share the bed with a restless partner and want genuine distance between you, or your nights regularly include a child or a large dog joining you. It also suits you if your bedroom is generous, at least 3m x 2.9m, and a smaller bed would look lost in it.
Consider another size if...
Your bedroom is smaller than our suggested 3m x 2.9m, or you need space for furniture around the bed. We'd recommend the UK king instead, which we suggest for rooms of at least 2.7m x 2.9m.

Madrid 1000 UK super king vs UK king: how much extra room do you get?
The UK super king is 30cm wider than the UK king and the same length, at 200cm. For two people sharing, the UK king gives 75cm each, while the UK super king gives 90cm each, which is 15cm more per person. If width is your main complaint about your current bed, that extra 15cm each is the reason to size up.
Is a Spring King Madrid 1000 super king big enough for two adults and a child?
For occasional night visits, yes. With 90cm each for two adults, a small child can slot in between without anyone being pushed to the edge. The medium firm pocket springs give a steady, even surface, although a child who arrives every single night will still leave the adults with a little less room than they'd like.
Will a restless partner still wake me on a Madrid 1000 super king?
Much less than on a narrower bed. The UK super king gives you 90cm each, so your partner is physically further away, and the individually pocketed springs limit how far their movement travels. Distance does most of the work here, because the polyester fibre fillings are fairly thin and won't absorb much motion on their own.
Can I share a Spring King Madrid 1000 UK super king with a large dog?
The 180 x 200cm surface gives you a realistic chance of sharing with a big dog and still sleeping well, especially compared with a UK king. Because each spring moves independently, a dog resettling at the foot of the bed should disturb you less. Expect the dog to claim some of your 90cm, though.
Will a Madrid 1000 UK super king fit through my doors and up the stairs?
Measure before you order. At 180 x 200cm and 25cm deep, a pocket spring mattress this size can struggle with tight landing turns, narrow doorways and doors that open inwards into a small hallway. Spring King doesn't publish a weight or folding guidance for this mattress, so check with the retailer if your stairs are awkward.
