Layer Details
- Space that works with the springs: At 75cm each for two people sharing, plus pocket springs that compress independently, one of you turning over is far less likely to wake the other.
- Room for different schedules: If one of you gets up hours before the other, the extra width lets the early riser slip out with less disturbance across the surface.
- Length for taller sleepers: The UK king is 10cm longer than the UK Double at 200cm, which means anyone approaching 6ft stops sleeping with their feet at the edge.
- An affordable upgrade size: This entry-level model keeps the cost of moving up from a UK double lower than most pocket sprung kings, so the size upgrade stays within reach.
- Support that suits sharing: Medium firm tension works for most back and front sleepers, so a couple with different sleeping positions can usually both get on with it.
This size suits you if...
You share every night and a UK double has started to feel tight, especially if one of you keeps different hours or a dog claims a corner of the bed as routine. It also suits you if either sleeper is approaching 6ft and wants the full 200cm length, or you want a first pocket sprung mattress in this size without a big spend.
Consider another size if...
Your bedroom falls short of the 2.7m x 2.9m we suggest as a minimum for a UK king. In that case the UK double would suit you better, needing at least 2.6m x 2.8m and giving up only 15cm of width.

Is a UK king worth it for couples on this mattress?
For most sharing couples, yes. The UK king is 15cm wider than the UK Double, and with 75cm each for two people sharing, the 800 pocket springs have room to do their job: each spring moves independently, so movement on one side carries less across the bed. If budget is tight, that width gain is the main thing you're paying for.
Is the Silentnight Pocket Essentials 800 king long enough for tall people?
The UK king measures 150 x 200cm, and that 200cm length is 10cm more than the UK Double offers. If either of you is approaching 6ft, the extra length is arguably a bigger everyday improvement than the width. Anyone comfortably over 6ft may still want to lie on a 200cm mattress in a showroom before committing.
What room size do I need for the Pocket Essentials 800 in a UK king?
We suggest at least 2.7m x 2.9m, with 3.2m x 3.2m feeling comfortable. That's our guidance rather than Silentnight's. New build master bedrooms often look adequate on the plans but shrink once wardrobes go in, so measure the usable floor after furniture, and check you can still open drawers and walk both sides of the bed.
Should I get the Pocket Essentials 800 in a king or super king?
The UK super king is 30cm wider than the UK king, and the two are the same length, so the choice is purely about width and floor space. We suggest at least 3m x 2.9m for the UK super king. If your room clears that and you regularly share with children or a dog, size up; otherwise the UK king is the easier fit.
