- Proper space for two: At 150cm wide you get 75cm each for two people sharing, which means you can change position without negotiating for territory.
- Length for taller sleepers: The UK king runs to 200cm, 10cm longer than the UK double, so anyone approaching six foot stops waking with their feet at the edge.
- Less disturbance across a wider bed: Pocket springs move independently, and spread across a king width that means one of you getting up early transmits very little to the other side.
- Extra firm without the board feel: The springs contour slightly to your shape, so the solid surface Silentnight promises still follows your body rather than fighting it.
- A firm feel that stays put at this size: Because each spring works alone, the extra firm support holds up under two different body weights rather than sagging toward the heavier sleeper.
This size suits you if...
You share the bed every night and a double has started to feel like a negotiation, especially if one of you keeps earlier hours and slips out while the other sleeps on. It also fits if either of you is approaching six foot and wants that 10cm of extra length over a UK double, or if you both prefer a genuinely solid surface and need width to go with it.
Consider another size if...
Your room falls short of the 2.7m x 2.9m we suggest for a UK king, or you want the most space this mattress offers. For tighter rooms we'd recommend the UK double; for maximum space, the UK super king, allowing at least 3m x 2.9m.

Is the Silentnight Pocket Essentials 1400 Ortho in a UK king big enough for two adults?
Yes, comfortably for most couples. The UK king measures 150 x 200cm, which works out at 75cm each for two people sharing. On an extra firm mattress that width is genuinely useful, because you rely more on repositioning than sinking in, and the room to do it makes the surface feel less restrictive.
What room size does the UK king Pocket Essentials 1400 Ortho need?
We suggest a bedroom of at least 2.7m x 2.9m for a UK king, which leaves walking space around the bed and room for doors and drawers to open. That's our guidance rather than Silentnight's. In a newer build master bedroom, measure with the wardrobes in place before committing, as they shrink the usable floor quickly.
Is the UK king long enough for someone over six foot?
It's the better bet. The UK king is 200cm long, or 6ft 6in, which is 10cm longer than the UK double. If one of you is tall, that length is often the real reason to size up, more so than width. Feet stop hanging over the end, which matters on a firm surface with little give.
Will a king size help if my partner gets up earlier than me?
It should. The pocket springs respond individually, so movement on one side doesn't drag the whole surface with it, and across 150cm of width there's simply more mattress between you. If your mornings run hours apart, the combination of independent springs and extra distance makes an early alarm far less likely to wake the other sleeper.
Should I choose the Pocket Essentials 1400 Ortho in a UK king or UK super king?
The UK king suits most couples: plenty of space without heavy demands on the room. The UK super king is 30cm wider at the same length, and we'd suggest a room of at least 3m x 2.9m for it. If a dog routinely claims part of the bed, that extra width can be the deciding factor.
