Layer Details
- Real space for two: At 75cm each for two people sharing, you can both change position without negotiating for territory.
- Less partner disturbance: If one of you gets up hours before the other, the wider surface puts more distance between you, so early alarms are less likely to wake the later riser.
- Length for taller sleepers: The UK king is 10cm longer than the UK double at 200cm, which matters more than width if one of you is approaching 6ft.
- Room for the routine intruder: If the dog treats the foot of the bed as its own, the extra width means it takes a share rather than the lion's share.
- Easier nights through pregnancy: Propping pillows and shifting position through the night is far more comfortable when you're not pressed against the edge or your partner.
This size suits you if...
You share the bed every night and a UK double has started to feel cramped, one of you is tall enough to want the 200cm length, or your nights involve pillows, a pet or different wake-up times and you need the width to absorb all of that without waking each other.
Consider another size if...
Your bedroom is smaller than the 2.7m x 2.9m we suggest for a UK king, or you sleep alone and the width would go unused. We'd recommend the UK double instead, where we suggest allowing at least 2.6m x 2.8m.

Is the Silentnight Just Sleep Snug king big enough for a couple?
Yes, comfortably for most. The UK king measures 150 x 200cm, giving 75cm each for two people sharing, which is 15cm more width between you than a UK double. Across couples upgrading sizes, that difference is usually felt straight away, especially if one of you moves a lot or keeps different hours.
How much bigger is the UK king than the double in this mattress?
The UK king is 15cm wider and 10cm longer than the UK double. The width is what most couples notice night to night, while the extra length is the quieter benefit: at 200cm, taller sleepers stop hanging their feet off the end. The Silentnight Just Sleep Snug also comes in a UK single and UK double if the king is too much.
Will a UK king version of this mattress fit my bedroom?
We suggest a room of at least 2.7m x 2.9m for a UK king, which is our guidance rather than Silentnight's. New build master bedrooms can be tighter than they first appear once wardrobes and drawers go in, so measure the free floor space, and remember you'll want walking room on both sides.
Where can I buy the Silentnight Just Sleep Snug in a king?
Availability shifts, so the most reliable answer is the live comparison on this page. The prices shown here are updated as retailers change them, which makes it a better guide than any figure we could print. It's the largest size this mattress comes in, so there's no super king to hold out for.
What are the dimensions of the Silentnight Just Sleep Snug UK king?
It measures 150 x 200cm, or 5ft x 6ft 6in in imperial. Standard UK king sheets fit, and a 230 x 220cm king duvet is the usual pairing. If you're replacing an older bed, check your frame is a genuine UK king, since EU sizes look similar but differ by a few centimetres.
