Layer Details
- UltraGel comfort layer. A gel infused foam layer that adjusts to your body's movements while helping to cool you down, which means pressure relief without the heat build-up plain foam can cause. It also has a degree of bounce back, so you shouldn't feel stuck in one position.
- Mirapocket springs. 2,000 pocket springs that move independently of one another, giving zoned support where your body needs it. Because each spring reacts on its own, movement on one side of the bed is far less likely to disturb the other.
Layer details from silentnight.co.uk product page, September 2026.
- Fits compact rooms: At 90cm wide it needs only 2.1m x 2.8m of floor space by our guidance, which leaves room for a desk or wardrobe in a child's bedroom.
- A gentle feel for lighter bodies: The medium soft surface gives more readily than a standard medium, which suits the lighter weights of children, teens and smaller adults sleeping solo.
- Cooling where one sleeper needs it: The gel infused comfort layer draws heat away, useful in a small room or loft space where warm air tends to gather around a single bed.
- Cheap, easy bedding: Standard single sheets and a 135 x 200cm single duvet fit, and both are the most widely stocked and affordable bedding of any UK size.
- Guest room ready: A UK single works well in a spare room that doubles as an office, keeping floor space usable during the day.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares floor space with a desk and storage, you're a lighter solo sleeper who wants a softer, cushioned feel, or you're furnishing a spare room that needs to keep working as an office. The 90 x 190cm footprint fits almost any UK bedroom, and the medium soft surface suits lighter weights well.
Consider another size if...
You're an adult who spreads out in your sleep, or two of you occasionally share the bed. We'd recommend the UK small double instead: it's 30cm wider than the UK single, the same length, and we suggest allowing 2.4m x 2.8m for it.

Will the Silentnight UltraGel 2000 UK single fit a bunk or mid sleeper frame?
The footprint fits: at 90 x 190cm it matches standard UK bunk and mid sleeper frames. Depth is the thing to check. This mattress is 31cm deep, which is tall for a raised frame, and guard rails need to sit well above the mattress surface to be safe. Measure your frame's maximum mattress depth before buying.
What room size do I need for the Silentnight UltraGel 2000 in a UK single?
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. In a child's room competing with a wardrobe and a desk, or under the slope of a loft conversion, the 90cm width is the easiest size to place.
Is the UK single UltraGel 2000 a good mattress for a child or teenager?
It's a sensible match. The medium soft feel gives a little more than a standard medium, and lighter bodies tend to get on well with that extra cushioning. The 2,000 pocket springs still provide proper support as a child grows. Heavier teens who prefer a firm surface may find it a little too forgiving.
Does the UK single work for two children sharing a room?
Yes, this is a common setup: two UK singles with a walkway between them. Each bed is 90cm wide, so measure your room against two mattresses plus space to move around both. The independently moving pocket springs matter less here than in a shared bed, but each child gets the same cooling gel layer.
