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.
- Fits where space is tight: At 3ft x 6ft 3in it leaves room for a wardrobe, desk and toy storage in a child's bedroom, and we suggest floor space of just 2.1m x 2.8m.
- Latex suits restless young sleepers: The latex layer responds quickly when you change position, which means a fidgety child or teen moves freely rather than sinking in and staying put.
- Zoned support in a growing-up size: The 1200 Mirapocket springs adjust to body weight individually, so a light teenager gets the same spinal alignment the springs give a heavier adult.
- Works on raised frames: At 26cm deep it suits many bunk, cabin and mid-sleeper frames, though you should check your frame's maximum mattress depth and guardrail height first.
- Sensible for guest rooms: A medium feel is a safe middle ground for visitors whose preferences you can't predict, and a UK single slots into a spare room that doubles as an office.
This size suits you if...
You're buying for one sleeper: a child moving up from a cot bed, a teenager, or an adult sleeping solo in a compact room. It also fits if you're kitting out a spare room or loft conversion where only a narrow footprint works, or a student room where the frame is provided and the mattress isn't.
Consider another size if...
You're an adult who shares the bed, or a solo sleeper who wants space to spread out. We'd recommend the UK double instead: it's 45cm wider, the same length, and we suggest a room of at least 2.6m x 2.8m.

Will the Silentnight Lift Renew 1200 UK single fit a bunk or mid sleeper?
In most cases, yes. The UK single is the standard size for bunk, cabin and mid-sleeper frames, and at 26cm this mattress is slimmer than many hybrids. Do check two things before ordering: your frame's stated maximum mattress depth, and that the guardrail on a top bunk still sits high enough above the mattress surface.
What room size do I need for the Silentnight Lift Renew 1200 in a UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That gives you a walkway and room for the door to open. If you're fitting two UK singles in a shared children's room or a guest room, measure for a walkway between the beds as well, rather than doubling that minimum.
Is the Lift Renew 1200 UK single a good choice for a child or teenager?
It's a reasonable fit. The medium feel and quick-responding latex suit lighter, restless sleepers who change position often, and the zoned springs adjust to body weight, so a growing teen isn't under-supported. It's a bigger spend than a basic children's mattress, but it's one they won't outgrow in feel.
Should I buy the UK single or the UK double for one adult?
If your room allows, the UK double gives a solo adult far more room to spread out: it's 45cm wider than the UK single and the same length, and we suggest a room of at least 2.6m x 2.8m for it. The UK single makes sense when the room is genuinely tight, or the bed shares space with a desk.
Is a UK single long enough for a taller sleeper?
The UK single runs 190cm, or 6ft 3in, which suits most people comfortably. Taller adults may want the extra 10cm of length the UK king offers, though that's a much wider bed too, at 60cm more than the UK single, and it needs a room of at least 2.7m x 2.9m.
