Layer Details
- Memory Foam Comfort Layer. A responsive memory foam layer that gently moulds to your body's contours, which means pressure points like hips and shoulders get some welcome relief. It absorbs energy as you move, so you feel cradled rather than bounced.
- Mirapocket Spring Support System. 1,000 individually nested pocket springs (counted on the king size, pro-rata for other sizes) that react independently to your body weight and movement. In practice this means zoned support that keeps your spine aligned and limits motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- Fits compact rooms: At 90cm wide, it leaves floor space for a desk, wardrobe and toy storage in a child's room, or two beds plus a walkway where siblings share.
- Firm support for growing sleepers: The firm feel with zoned pocket spring support keeps a child or teenager's spine well aligned as they grow.
- Works on raised frames: At 25cm deep, it sits within the depth limits most bunk, cabin and mid-sleeper frames allow, although you should check your frame's maximum before buying.
- Practical for guest and spare rooms: A sensible pick for a spare room that doubles as an office, or for pairing two UK singles where guests may not want to share.
- Allergy-friendly for kids' rooms: The Purotex probiotic treatment combats allergens, which means a little reassurance if your child is sensitive to dust.
- Cheap, easy bedding: Standard single sheets and duvets are the most widely stocked and least expensive of any UK size, useful when children go through bedding quickly.
This size suits you if...
You're buying for a child or teenager moving up from a cot or toddler bed, you're a solo adult in a compact room, student flat or first rental where the frame is provided and the mattress isn't, or you're kitting out a spare room, bunk bed or mid sleeper where the standard 90 x 190cm footprint is what the frame takes.
Consider another size if...
You're an adult who moves around in the night, or two of you will ever share the bed. We'd recommend the UK double instead, which is 45cm wider and the same length; allow at least 2.6m x 2.8m of floor space for it.

Is the Silentnight Memory 1000 UK single good for a child's bed?
Yes, provided your child gets on with a firm feel. The zoned pocket spring support keeps a growing spine aligned, and the Purotex treatment combats allergens, useful for dust-sensitive children. At 90 x 190cm it fits the standard UK children's bed frame, and it will last well beyond the teenage years in size terms.
Will the Silentnight Memory 1000 single fit a bunk or mid sleeper?
The UK single's 90 x 190cm footprint matches standard UK bunk, cabin and mid-sleeper frames. The mattress is 25cm deep, which most raised frames accept, but check your frame's maximum mattress depth against the guard rail height first. Remember it's rotate-only, so factor in turning it on a top bunk.
How much floor space does a UK single mattress need?
The mattress itself is 90 x 190cm, and we suggest allowing at least 2.1m x 2.8m of floor space so you can get around the bed and open doors and drawers comfortably. That modest footprint is why the UK single works in box rooms, loft conversions with a narrow usable strip, and shared children's bedrooms.
Is a single big enough for an adult on this mattress?
For one average-sized adult who sleeps fairly still, yes, and the firm feel helps you use the full 90cm width without rolling toward an edge. Restless sleepers or taller, broader adults often find it snug. If that sounds like you, the UK small double is 30cm wider and the same length; allow at least 2.4m x 2.8m for it.
