Layer Details
ActiveBreathe layer
This comfort layer feels like memory foam but is ten times more breathable, which means contouring comfort without the overheating foam is known for. If you tend to sleep warm, this is the feature to pay attention to.
Mirapocket® spring system
Silentnight's Mirapocket® system uses 800 pocket springs in the king size. Each spring moves independently, so the mattress responds to your shape and reduces the ripple effect when a partner shifts position.
Eternity layer
The base Eternity layer gives the mattress extra stability and long lasting resilience. In practice, that means the firm feel should hold up rather than softening quickly.

Key benefits
- Fits where space is tight: At 90cm wide it leaves room for a desk, wardrobe and toy storage in a child's bedroom, or two beds with a walkway between them for sharing siblings.
- Firm support for growing sleepers: The firm Mirapocket® spring system gives children and teens a stable, supportive surface rather than a soft one they sink into.
- Cooler than plain foam: The ActiveBreathe comfort layer contours like memory foam but breathes far better, useful in small rooms that warm up quickly overnight.
- Practical for spare rooms: A single suits a study that doubles as guest space, and the Eternity base layer helps the firm feel last even with only occasional use.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and they're the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for a child's room or a teenager and want firm, durable support at the standard one-person width, your spare room needs a guest bed that won't crowd the desk, or you're a single adult in a compact bedroom, a loft conversion or a first flat where a 90cm footprint is the only one that fits.
Consider another size if...
You're an adult who shares the bed, or a solo sleeper who spreads out and finds 90cm restrictive. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m for it.

FAQ's
Is the Silentnight Revitalise Refresh 800 UK single good for a child?
Yes, with one caveat. The firm feel gives a growing child solid, even support, and the ActiveBreathe layer keeps things cooler than standard foam. Lightweight side sleepers, including smaller children, may find it slightly unyielding at the shoulder and hip, so it's better suited to back and front sleepers or heavier teens.
Will the UK single fit a bunk bed or mid sleeper frame?
The 90 x 190cm footprint is the standard for bunk, cabin and mid sleeper frames, so width and length should be fine. Depth is the thing to check: at 27.5cm this is a reasonably tall mattress, and raised frames need the guard rail to sit well above the mattress surface. Measure your frame's maximum mattress depth first.
What room size do I need for the Silentnight Revitalise Refresh 800 UK single?
We suggest allowing at least 2.1m x 2.8m of floor space. That leaves enough room to walk around the bed and open drawers or wardrobe doors. In a loft conversion, the single's narrow 90cm footprint also makes it easier to position under a sloping ceiling than any wider size.
Is a UK single big enough for an adult guest room?
For occasional guests, yes. At 3ft wide it sleeps one adult comfortably for a night or two, and the firm support suits a range of visitors. If the room allows, two UK singles give you flexibility for couples or two separate guests, and each only needs a 90 x 190cm footprint.
How much smaller is the UK single than the UK double?
The UK single is 45cm narrower than the UK double, and the two are the same length at 190cm. That extra width is the difference between a one-person bed and one an adult couple can share, so if the mattress is for two people the UK double is the sensible starting point.
