Layer Details
- Intense™ sleep surface. The sleep surface is woven with Silentnight's Intense fabric technology, approved by Oeko-tex and free from FR chemical treatments. That means fewer chemicals between you and the mattress, a small but genuine reassurance.
- Luxurious Latex. A latex comfort layer that moves when you do, giving cushioning and pressure relief with even weight distribution. In practice this means freedom of movement: you won't sink in and stay put.
- 1200 Mirapocket® springs. 1200 individual pocket springs adjust to your body weight, with zoned support that Silentnight states is scientifically proven to improve spinal alignment and posture. Each spring works independently, so a restless partner is less likely to disturb you.
Layer details from silentnight.co.uk product page, September 2026.
- 75cm each for couples: Two people sharing get 75cm of width each, which means fewer accidental elbows and less negotiating over the middle of the bed.
- Less disturbance on different schedules: If one of you gets up hours before the other, the independent pocket springs and the wider surface both reduce how much that early exit registers.
- Extra length for taller sleepers: At 200cm, the UK king is 10cm longer than the UK double, so anyone approaching six foot stops sleeping with their feet at the edge.
- Latex that suits restless sharers: The latex layer responds quickly when you change position, which means you can shift about at night without dragging the whole surface with you.
- Room for a bed-sharing dog: If a dog claims a corner every night, the 150cm width leaves both humans usable space rather than one of you clinging to the edge.
This size suits you if...
You share the bed every night and a double has started to feel cramped, you and your partner keep different hours and want movement to travel less, or one of you is tall enough that the extra 10cm of length over a UK double matters as much as the width.
Consider another size if...
Your bedroom is under our suggested 2.7m x 2.9m minimum, or you sleep alone. In either case we'd recommend the UK double instead, which needs a slightly smaller room, at least 2.6m x 2.8m by our guidance.

Is the UK king Silentnight Lift Renew 1200 big enough for two adults?
Yes, for most couples. At 150 x 200cm you each get 75cm of width, which is a comfortable amount of personal space for two people sharing every night. If you regularly share with a child or a large dog as well, the UK super king adds another 30cm of width.
How much bigger is the UK king than the double for this mattress?
The UK king is 15cm wider and 10cm longer than the UK double. The width is what you notice night to night, since it goes to personal space, while the extra length is the difference that matters if either of you is tall. It does need a slightly larger room, though: allow at least 2.7m x 2.9m.
What room size do I need for the Silentnight Lift Renew 1200 in a UK king?
We suggest at least 2.7m x 2.9m, with more feeling comfortable once wardrobes and bedside tables are in. New build master bedrooms can be tighter than they first appear, so measure with your furniture in place before committing. If the room falls short, the UK double suits rooms from 2.6m x 2.8m.
Is the UK king long enough for someone over six foot?
At 200cm, or 6ft 6in, it gives a six-footer roughly a head's worth of clearance, which most tall sleepers find enough. If length is your only complaint with your current bed, note that the UK super king is the same length as the UK king; sizing up beyond a king buys width, not extra length.
Will this mattress in a king stop my partner waking me up?
It should help noticeably rather than eliminate it. The 1200 Mirapocket springs move independently, so a partner turning over or getting up early transfers less motion across the bed, and the 75cm of width each adds distance too. Very light sleepers who want maximum separation may prefer the UK super king, which needs a room of at least 3m x 2.9m.
