Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body to relieve pressure, which means less tossing to find a comfortable position. The graphite actively transfers heat away from you, and Silentnight claims this makes it 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket® springs, each held in its own individual pocket so they respond to every movement independently. In practice that means zoned support for your back and less motion transfer across the bed.
Layer details from silentnight.co.uk product page, September 2026.
- Fits compact rooms easily: At 90cm wide it slots into box rooms and loft conversions where a wider bed simply wouldn't, and we suggest allowing at least 2.1m x 2.8m of floor space.
- Cooling foam for teens who run warm: The graphite-infused Memory Cool™ layer draws heat away from the body, useful in small bedrooms that heat up quickly overnight.
- Full spring count in a small size: You get 2000 Mirapocket® springs even at this width, so a single sleeper gets the same responsive, zoned support as someone in a UK king.
- Spare rooms that do double duty: In a room that's an office on weekdays and a guest room at weekends, the 90cm width leaves space for a desk alongside the bed.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked bedding of any UK size.
This size suits you if...
You're buying for one sleeper: a child moving up from a cot bed, a teenager who sleeps hot, a student flat where the frame is provided but the mattress isn't, or a guest bed that sees occasional use. It also makes sense if your room is tight, since a UK single needs only around 2.1m x 2.8m of floor space, leaving room for a wardrobe and desk.
Consider another size if...
You're an adult who shares the bed, or a restless solo sleeper who wants room to spread out. 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.

Is the Silentnight Memory Cool 2000 single suitable for a bunk bed?
Check your frame first. This mattress is 31cm deep, which is deeper than many bunk, cabin and mid-sleeper frames allow, since guard rails need to sit well above the sleep surface. The 90 x 190cm footprint matches standard UK bunk frames, but Silentnight's depth means you should measure from the base to the top of the rail before buying.
Is the Silentnight Memory Cool 2000 UK single good for a child's room?
Yes, with one caveat. The medium feel and pressure-relieving foam suit growing children and teens, and the cooling layer helps in small rooms that get stuffy. At 90cm wide it leaves floor space free for toy storage, a wardrobe and a desk. Lighter children may sink into the foam less, so the moulding feel will be subtler for them.
What room size do I need for a UK single mattress?
We suggest allowing at least 2.1m x 2.8m of floor space, which is our own guidance rather than Silentnight's. That leaves enough room to walk around the bed and open drawers. If two siblings are sharing, you'll want extra width for a walkway between the two beds, so measure carefully before committing.
Is a UK single big enough for an adult?
For one adult, yes, though it's snug. At 90 x 190cm you have the classic one-person width, fine for a guest bed or a student room but limiting if you move around a lot at night. Taller sleepers should note the UK single is 10cm shorter than the UK king, so anyone well over 6ft may prefer sizing up.
