Layer Details
Base pocket springs
The interior starts with a base layer of pocket springs. This gives the mattress its underlying support, so the layers above have a stable foundation.
Tablet pocket springs
A layer of tablet pocket springs sits on top of the base layer, each one wrapped in its own cloth sleeve. Because each spring works on its own, the surface can follow your shape rather than moving as one piece.

Key benefits
- More room each than a double: You each get 75cm on the UK king, which means 7.5cm more per person than a UK double, enough to stop elbows meeting in the night.
- Less disturbance from your partner: Its pocket springs are individually sleeved, which means one person's movement travels less across the surface, and the wider UK king puts extra distance between you as well.
- Length for a taller sleeper: At 200cm, the UK king is 10cm longer than a UK double, so a partner around six foot can stretch out without feet pressing past the edge.
- Fits rooms a super king won't: We suggest at least 2.7m x 2.9m for a UK king, a more forgiving footprint than the 3m x 2.9m we'd allow for a UK super king.
- Easy bedding to find: King sheets fit, and a 230 x 220cm king duvet gives you both enough cover to stop the nightly tug of war.
This size suits you if...
You and your partner keep different hours, so one of you is up and out while the other is still asleep, and you want more distance between you. It also suits you if one of you is over six foot and the UK double has started to feel short.
Consider another size if...
Your bedroom is smaller than our suggested 2.7m x 2.9m once wardrobes and bedside tables are in. We'd recommend the UK double instead, which needs at least 2.6m x 2.8m.

FAQ's
Will a UK king Silentnight Geltex Mirapocket 2000 Pillowtop fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, and 3.2m x 3.2m if you want comfortable space to walk round both sides. New build master bedrooms can feel smaller than the floor plan suggests once fitted wardrobes go in, so measure from the wardrobe doors rather than the walls.
Is a UK king long enough for someone over 6ft?
The UK king is 200cm long, which is 10cm more than a UK double. For a partner around six foot, that extra length is often the real reason to upgrade, because it stops feet sitting right at the edge. The UK super king is the same length, so going wider won't add any more.
How much space do two people get on a king size mattress?
A UK king gives 75cm each for two people sharing. A UK double gives 67.5cm each, so the UK king offers 7.5cm more per person. It sounds modest, but it is usually the difference between brushing against each other all night and sleeping undisturbed.
Should we get the Geltex Mirapocket 2000 Pillowtop in a UK king or super king?
The UK super king gives 90cm each, so the UK king gives you 15cm less per person. If you sleep restlessly or share with a dog, the UK super king may suit you better, but it needs at least 3m x 2.9m. In tighter rooms, the UK king is the more practical choice.
What size duvet do I need for a king size mattress?
A 230 x 220cm king duvet is the right match, along with king sheets. Couples who fight over the covers sometimes size up the duvet, but the standard king duvet already gives both of you enough to tuck in on a 150 x 200cm mattress.
