Layer Details
- Memory Cool™. A graphite-infused memory foam that moulds to your body, relieving pressure and absorbing energy as you move. The graphite actively transfers heat away from you, which Silentnight says creates a sleep environment 15% cooler than standard memory foam.
- Mirapocket® springs. 2000 Mirapocket springs sit in individual pockets, each responding to your movement independently. In practice that means zoned support where you need it and less motion transfer across the bed.

- Fits where floor space is fought over: At 90cm wide it leaves room for a desk, wardrobe and storage in a child's or teenager's bedroom, which bigger sizes rarely manage.
- Grown-up comfort in a one-person size: You get the same graphite-infused Memory Cool foam and 2000 Mirapocket springs as the larger sizes, so a solo sleeper isn't settling for a lesser mattress.
- Cooler foam for smaller rooms: Box rooms and lofts can run warm, and Silentnight says the graphite layer sleeps 15% cooler than standard memory foam, a useful trait in a snug space.
- A guest bed people will actually enjoy: The cushioned pillow top gives a spare room single a softer, more welcoming feel than the thin mattresses guest beds often end up with.
- Check depth against raised frames: At 31cm deep it may sit above the safety rail on bunk, cabin and mid-sleeper frames, so measure your frame's maximum mattress depth first.
This size suits you if...
You sleep alone and want proper memory foam pressure relief in a compact footprint, you're furnishing a child's or teenager's room where the bed has to share space with a desk and wardrobe, or you're upgrading a spare room single so guests get more than a token mattress. It also suits student rooms and first flats where the frame is provided and only the mattress is yours to choose.
Consider another size if...
You're an adult who spreads out at night or occasionally shares the bed, and 90cm of width will feel restrictive. We'd recommend the UK small double instead: it's 30cm wider, the same length, and we suggest a room of at least 2.4m x 2.8m for it.

Will the Silentnight Memory Cool 2000 UK single fit a bunk or mid sleeper?
Be careful here. This mattress is 31cm deep with a pillow top, which is deeper than many bunk, cabin and mid-sleeper frames allow, since the mattress must sit below the safety rail. Check your frame's stated maximum mattress depth before buying. For a standard single bed frame or divan, the 90 x 190cm footprint fits as normal.
What size room do I need for a UK single Memory Cool 2000?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single. That gives you room to walk alongside the bed and open drawers or a wardrobe. In a loft conversion or box room, the 90cm width also makes it easier to position the bed under a sloped ceiling where a wider mattress wouldn't go.
Is a UK single Silentnight Memory Cool 2000 big enough for an adult?
For one adult, yes. At 90 x 190cm it's the standard UK one-person size, and the 2000 Mirapocket springs give full support across that width. Taller sleepers should note the UK single is 10cm shorter than the UK king, so if you're over six foot and have the space, sizing up is worth considering.
Is this mattress a good choice for a child's or teenager's bedroom?
It works well for teenagers, who get pressure relief at the shoulders and hips and a cooler surface than standard memory foam. For younger children it's arguably more mattress than they need, though nothing about it is unsuitable. The 90cm width leaves space in a shared or small room for storage, a desk and a clear walkway.
Does the UK single suit a spare room that doubles as an office?
Yes, this is where the single earns consideration for adults. A 90 x 190cm bed leaves the rest of the room free for a desk and shelving, and guests still get the cushioned pillow top and pocket spring support rather than a basic budget mattress.
