Layer Details
- Cool-to-touch sleep surface. The UltraGel™ cool-to-touch layer uses hyper-conductive technology woven into the surface fabric, which means the mattress feels instantly cool when you lie down. It's the feature to care about if overheating regularly wakes you.
- Gel-infused layer. This gel-infused foam responds to your movements and is 5x more breathable than standard memory foam, according to Silentnight. In practice, that means the contouring of foam with less of the heat build-up.
- Pillowtop. A pillowtop surface adds a plush, cushioned top to the mattress. It gives that sink-in, hotel-bed feel rather than a firmer sleeping surface.
- Pocket spring support system. 2000 Mirapocket® springs work independently, which means one side of the bed can move without disturbing the other. The zoning is scientifically proven, Silentnight says, to improve spinal alignment and posture.

- Leaves room for everything else: At 90cm wide, the UK single leaves space for a desk and wardrobe in a child's bedroom, which means the bed doesn't take over the floor.
- Softness that suits lighter bodies: The medium soft rating gives children and slim adults some give around the shoulders and hips, where a firmer mattress might feel unyielding under a lighter frame.
- Cooler nights in small, warm rooms: If a teenager's box room gets stuffy, the cool-to-touch surface and breathable gel layer should help reduce that trapped-heat feeling through the night.
- A plush single for guests: The pillowtop gives visitors a hotel-style sink-in feel, a step up from the thin singles many spare rooms end up with.
- Two beds side by side: The narrow footprint makes a pair of UK singles realistic for siblings sharing a room or a guest room set up for two, with a walkway between them.
This size suits you if...
You're buying for a child or teenager who sleeps warm and likes a softer bed, or you're furnishing a compact spare room or study that needs a comfortable guest bed without losing the floor space.
Consider another size if...
You're an adult who sprawls or needs room to turn over comfortably. We'd recommend the UK small double instead: it's 30cm wider and the same length, and we suggest at least 2.4m x 2.8m for it.

Can I put a Silentnight UltraGel Pocket 2000 UK single on a bunk bed?
Possibly, but check first. The mattress is 33cm deep, which is thick for a single, and many bunks, cabin beds and mid sleepers set a maximum mattress depth so the guard rail stays high enough. Look up the frame maker's limit before you buy. Silentnight doesn't list a figure for raised frames on this model.
Is the UltraGel Pocket 2000 UK single a good mattress for a teenager?
For many teenagers, yes. The medium soft feel suits lighter bodies, and the cool-to-touch surface helps a teenager who overheats in a small bedroom. At 190cm long, a UK single can feel short for a very tall teen. The UK king adds 10cm of length if that's likely to become a problem.
What size room do I need for a UK single Silentnight UltraGel mattress?
We suggest at least 2.1m x 2.8m of floor space for a UK single. That leaves room to get in and out of the bed and to open a wardrobe or drawers. If you're fitting two singles for siblings, allow for a clear walkway between the beds as well.
Will a UK single pillowtop mattress work in a loft conversion with a sloping ceiling?
The 90cm width suits the narrow flat area under a slope. The catch is height: a 33cm pillowtop raises the sleeping surface more than a slim mattress would, so measure the headroom above the frame you're using. Sitting up in bed under a low slope is where a deep mattress becomes noticeable.
Should I choose a UK single or UK small double UltraGel Pocket 2000 for a guest room?
A UK single suits one guest in a tight room, or a pair of singles for two guests who won't share a bed. A single adult who wants more space will find the UK small double more comfortable: it's 30cm wider, and we suggest at least 2.4m x 2.8m of floor space for it.
