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.

- 7.5cm more each than a UK double: Moving up from the UK double gives each of you 7.5cm more width, which means fewer elbows in the night and room to shift without crossing onto your partner's side.
- Less disturbance on different schedules: The springs work separately, and with 75cm each there is more distance between you, which helps if one of you gets up hours before the other.
- 10cm longer than a UK double: At 200cm long, the UK king is 10cm longer than the UK double, which means a partner over six foot is less likely to find their feet hanging past the end.
- Asks less of your bedroom than a UK super king: We suggest at least 2.7m x 2.9m, against at least 3m x 2.9m for the UK super king, which matters in a new build master bedroom once wardrobes are fitted.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is up and out long before the other wakes, or a partner over six foot needs the extra length as much as the extra width.
Consider another size if...
Your bedroom falls short of our suggested 2.7m x 2.9m minimum. We'd recommend the UK double instead, and for that size we suggest at least 2.6m x 2.8m.

How much space does each person get on the Madrid 1000 UK king?
Two people sharing the UK king get 75cm each. That is 7.5cm more each than the UK double, and 15cm less each than the UK super king, which gives 90cm each. For most couples moving up from a double, the extra width is enough to stop you drifting into each other's space.
Is the Spring King Madrid 1000 king size long enough if you're over 6ft?
The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. The UK super king is the same length, so sizing up beyond the UK king adds width, not length. If height is your main reason for upgrading, the UK king already gives you the full length available.
Will I feel my partner moving on a Madrid 1000 UK king?
You should feel less than on a UK double. The 1,000 pocketed springs each move on their own, and the UK king gives 75cm each against 67.5cm on the UK double, so there is slightly more space for movement to settle before it reaches you. A restless partner may still be noticeable on a medium firm spring mattress.
Madrid 1000 UK king or UK super king for a couple with a dog on the bed?
If the dog sleeps on the bed most nights, the UK super king gives 90cm each against 75cm on the UK king, so you lose less space to it. The trade-off is room size: we suggest at least 3m x 2.9m for the UK super king, compared with at least 2.7m x 2.9m for the UK king.
