Layer Details
- Intense™ sleep surface. The top surface, which Silentnight states is scientifically proven to reduce cortisol levels and morning stress brought on by the menopause. In practice, this is the layer aimed at calmer, less disrupted mornings.
- Breathable Sleep System. A layer designed to reduce night sweats by enhancing breathability and moving heat and moisture away from your body. If you tend to sleep hot, this is the part of the build doing the heavy lifting for you.
- Mirapocket® springs. 1600 individual pocket springs that adjust to your body weight, giving zoned, tailored support. Each spring moves independently, which means less motion transfer if you share a bed.
Layer details from silentnight.co.uk product page, September 2026.
- Fits compact rooms: At 90cm wide it needs just 2.1m x 2.8m of floor space by our guidance, so a small bedroom or loft conversion can still take it comfortably.
- Cooling for one: The Breathable Sleep System moves heat and moisture away from your body, which means a solo sleeper with night sweats gets the full benefit without paying for unused width.
- Full spring count in a smaller size: You get the same 1600 Mirapocket springs adjusting to your body weight, so zoned support isn't diluted by choosing the smallest size.
- Guest room friendly: A single suits spare rooms that double as an office, leaving space for a desk while still giving visitors a genuinely supportive medium hybrid.
- Check raised frames first: At 30.5cm deep it sits tall for bunk, cabin and mid-sleeper frames, so measure against the guard rail before buying for a child's raised bed.
This size suits you if...
You sleep alone and menopause-related overheating is disrupting your nights, or you're furnishing a spare room that has to earn double duty as an office. It also suits a teenager's room where the bed competes with a desk and wardrobe for floor space, provided the frame is a standard low base rather than a raised sleeper.
Consider another size if...
You share the bed, even occasionally, as 90cm is snug for one adult and unworkable for two. We'd recommend the UK double instead; it's 45cm wider, the same length, and needs a room of at least 2.6m x 2.8m.

What size is the Silentnight Lift Breathe UK single?
It measures 90 x 190cm, which is 3ft x 6ft 3in. That's the standard UK one-person size, so it fits any ordinary single bed frame and takes standard single sheets. Allow at least 2.1m x 2.8m of floor space so you can still move around the room and open drawers.
Will the Silentnight Lift Breathe single fit a bunk or mid sleeper?
The width fits, but the depth needs checking. This mattress is 30.5cm deep, which is taller than many raised frames allow. On a bunk bed the guard rail must still sit safely above the mattress surface, so measure the maximum depth your frame permits before ordering. For low or standard single frames, depth isn't an issue.
Is the UK single Lift Breathe big enough for an adult?
For one adult sleeping alone, yes: 90cm is the standard solo width and the 1600 pocket springs give the same zoned support as the larger sizes. If you're a restless sleeper or simply used to more room, the UK double is 45cm wider and the same length, which is a noticeable upgrade if your bedroom can take it.
Is a single Lift Breathe long enough for a tall sleeper?
The UK single is 190cm long, the same length as the UK small double and UK double. Taller sleepers may want the extra length of the UK king, which is 10cm longer as well as 60cm wider, though that needs a room of at least 2.7m x 2.9m by our guidance.
Where can I buy the Silentnight Lift Breathe in a single?
Compare the retailers listed on this page; the prices shown here are updated as retailers change them, so it's worth checking back rather than assuming the first price you saw still stands. Availability of the UK single can differ from the larger sizes, as stockists don't always carry the full range.
