Layer Details
- Cool-to-touch sleep surface. The UltraGel cool-to-touch comfort layer uses hyper-conductive technology woven into the surface fabric, which means an instant cooling effect when you get into bed. It's the layer doing the most work for hot sleepers.
- Gel-infused layer. Beneath the surface sits a gel-infused layer that responds to your movements as you shift in the night. Silentnight states it's five times more breathable than standard memory foam, so heat has somewhere to go rather than building up around you.
- Support System. The base holds 2000 Mirapocket springs that move independently, which means pressure relief tailored to your shape rather than the whole surface dipping. The zoning is, per Silentnight, scientifically proven to improve spinal alignment and posture.

- Proper space for one: At 30cm wider than the UK single, a solo adult can change position freely, which the medium/soft feel encourages if you like to sink in a little.
- Fits rooms a double crowds: Being 15cm narrower than the UK double, it can be the difference between a door that clears the bed and one that doesn't.
- Cooling in a compact room: Smaller bedrooms often run warmer, so the cool-to-touch UltraGel surface matters more here than it might in a larger, airier space.
- All 2000 springs, smaller footprint: The spring count doesn't drop with the size, so the zoned support Silentnight builds in is unchanged in the UK small double.
- Sensible for a guest room: Occasional visiting couples can share it comfortably enough, while a lone guest gets a genuinely generous bed.
This size suits you if...
You're a solo sleeper who has outgrown a single and wants room to spread out, your bedroom is compact and a full double would leave no floor space, or you're furnishing a guest room where couples stay occasionally rather than nightly. Allow at least 2.4m x 2.8m of floor space, which is our suggestion rather than Silentnight's.
Consider another size if...
You share the bed every night, because two adults on 120cm of width will feel each other's every turn. We'd recommend the UK double instead, which is 15cm wider; allow at least 2.6m x 2.8m for it.

How big is the Silentnight UltraGel 2000 in a small double?
The UK small double measures 120 x 190cm, which is 4ft x 6ft 3in. That's 30cm wider than the UK single at the same length. Bear in mind the 33cm depth when buying fitted sheets, as standard small double bedding can be a tight fit on a mattress this deep.
What room size do I need for a small double UltraGel 2000?
We suggest a room of at least 2.4m x 2.8m, which leaves enough space to walk around the bed and open drawers. That's our own guidance, not Silentnight's. If your room is smaller than that, the UK single is 30cm narrower and we suggest at least 2.1m x 2.8m for it.
Can two people share the UltraGel 2000 small double?
For the odd night, yes. The independent Mirapocket springs keep motion transfer low, which helps when two people share a narrower bed. Every night is another matter: the medium/soft feel means you both settle in, and on 120cm of width you'll notice each other. Nightly couples would be better served by the UK double.
Is the small double UltraGel 2000 worth it for one person?
This is arguably the size where it makes most sense. A solo sleeper gets real room to stretch, and the gentler medium/soft feel suits side sleepers who move around during the night. If you're a heavier back or stomach sleeper you may sink further than is comfortable, but that's true of every size, not this one specifically.
Where can I find the best price on this size?
Prices for the UK small double change often, so the most reliable answer is the live comparison table on this page, which is updated as retailers change their prices. Small double is sometimes priced closer to the UK single than the UK double, so it can be a quietly good-value option.
