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.
- A shared size for typical UK bedrooms: At 135 x 190cm (4ft 6in x 6ft 3in), it leaves space for wardrobes and drawers in the average British bedroom, where larger sizes often don't.
- Independent springs across a shared surface: The 1200 Mirapocket springs move individually, which means a partner turning over on their 67.5cm of the bed is less likely to wake you.
- Latex that helps in a narrower shared bed: Latex responds quickly when you change position, useful on a UK double where two people have less room to shift about.
- Room for bedside tables on both sides: Allow at least 2.6m x 2.8m and most rooms will still take a table each side, something a UK king often rules out.
- Easy to dress: Standard double sheets and duvets fit, stocked everywhere at every price, handy if you're kitting out a whole home at once.
This size suits you if...
You share the bed every night and your room sits around the typical UK size, where a king would leave you squeezing past the footboard. It also suits a guest room that hosts visiting couples, since the medium feel is forgiving enough for most sleepers. And if you sleep alone but like to spread out, or share with a dog who claims a corner, the extra width over a single is genuinely useful.
Consider another size if...
You and your partner both like space and your room is comfortably larger than average. The UK king is 15cm wider and 10cm longer, and we'd recommend it if you can allow at least 2.7m x 2.9m.

Is the Silentnight Lift Renew 1200 UK double big enough for a couple?
For most couples, yes. Two people sharing get 67.5cm of width each, and because the 1200 pocket springs move independently, one person turning is less likely to disturb the other. If either of you is broad-shouldered or a restless sleeper, the UK king adds 15cm of width and 10cm of length.
What room size do I need for the Lift Renew 1200 in a UK double?
We suggest a minimum of 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That's our guidance rather than Silentnight's, and it assumes you want to walk around the bed and open drawers without shuffling sideways. Bedside tables on both sides are usually still possible at these sizes.
Does the Silentnight Lift Renew 1200 come in a small double?
No. Silentnight makes this mattress in four sizes: UK single, UK double, UK king and UK super king. If your room is tight, note that the UK double is 45cm wider than the UK single but the same length, so dropping down saves width only, and it's really a one-person bed.
Is the Lift Renew 1200 double a good choice for a guest room?
It's a sensible fit. The medium feel suits most visitors without being divisive, and the 135 x 190cm footprint leaves room for a wardrobe and drawers in a second bedroom. Standard double bedding keeps things simple too. A couple used to a king will find it cosier than home, but for occasional stays that rarely matters.
Should a solo sleeper choose the UK double of this mattress?
If you like to spread out, or share with a pet who claims a corner, the UK double gives you 45cm more width than the UK single at the same length. The latex layer lets you move freely across all of it rather than settling into one spot. For a solo sleeper it's a small luxury rather than a necessity.
