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.

Key benefits
- Fits compact rooms: At 90cm wide it slots into small bedrooms and loft conversions with sloped ceilings, and we suggest allowing at least 2.1m x 2.8m of floor space.
- Cooling for warm little sleepers: The cool-to-touch UltraGel surface gives that instant chill on contact, which children and teens who run hot at night will feel straight away.
- A gentle feel for lighter bodies: The medium/soft feel suits lighter sleepers, so a child or teen sinks in comfortably rather than perching on a surface built for heavier adults.
- Guest-room friendly: In a spare room that doubles as an office, or a guest room with two beds, the 90cm width keeps a walkway clear.
- Hotel presence in a small size: The 33cm depth gives a single bed a substantial, grown-up look, with the caveat that deeper fitted sheets are a must.
This size suits you if...
You're buying for a child's or teenager's room where the bed shares space with a desk and wardrobe, you're kitting out a guest room or a spare room that doubles as an office, or you're a solo adult in a compact bedroom, perhaps a first flat or student room where the frame came with the tenancy but the mattress didn't.
Consider another size if...
You're an adult who wants more shoulder room, or you share the bed. The UK small double is 30cm wider and the same length; we suggest a room of at least 2.4m x 2.8m for it.

FAQ's
Will the UK single UltraGel 2000 fit a bunk bed or mid sleeper?
The 90 x 190cm footprint matches standard UK bunk and mid-sleeper frames, but the 33cm depth is the sticking point. Raised frames need the mattress to sit below the guard rail for safety, and many specify a maximum depth well under 33cm. Check your frame's stated limit before buying; for most bunks this mattress will be too tall.
What room size do I need for a single UltraGel 2000?
We suggest allowing at least 2.1m x 2.8m of floor space for a UK single, which gives you room to walk around the bed and open drawers or wardrobe doors. That makes it workable in box rooms, loft conversions where only a narrow footprint fits under the slope, and children's rooms where the bed competes with toy storage and a desk.
Is the UK single UltraGel 2000 big enough for an adult?
At 90cm wide and 190cm long it works for a solo adult of average height, and the medium/soft feel suits lighter side sleepers particularly well. Taller adults may find their feet near the edge, since the UK single is 10cm shorter than the UK king. For everyday adult use with room to spread out, consider the UK small double, which is 30cm wider.
Is this a good mattress for a child's bed?
In many ways yes: the medium/soft feel is gentle on lighter bodies, and the cool-touch surface helps children who overheat at night. Two checks first. The 33cm depth rules out most raised and cabin frames, and it sits high on a standard frame too, which matters for younger children getting in and out.
Will standard single fitted sheets fit this mattress?
Standard single sheets match the 90 x 190cm footprint, but the 33cm depth is deeper than many standard fitted sheets allow, so corners can ping off overnight. Look for single sheets labelled deep or extra deep. A standard single duvet (135 x 200cm) fits with no issues.
