Layer Details
- Cool-to-touch sleep surface. The SensICE fabric gives an instant cooling effect against your skin, drawing heat away from your body. In practice, that means the bed feels cool when you climb in rather than warming up straight away.
- Gel infused comfort layer. A responsive gel infused layer that adapts as you move and bounces back. You get cushioning without the slow, stuck-in feeling some soft foams can have.
- Extremely breathable foam. Silentnight states this foam is 5X more breathable than memory foam, working alongside the gel layer. Air moves through it more freely, which helps stop heat gathering under you overnight.
- Plush pillowtop. A boxtop layer that adds a soft, soothing top surface. It's a big part of why this mattress feels so cushioned on first contact.
- Spring support system. 2,000 Mirapocket springs combine with 1,000 mini springs for pressure relief and undisturbed sleep. Each spring moves on its own, so you feel supported where you need it and less of your partner's movement.
Layer details from silentnight.co.uk product page, September 2026.
- Room to sprawl on your own: The UK small double is 30cm wider than the UK Single, which means a restless solo sleeper can turn and stretch without meeting the edge.
- Soft comfort in a smaller footprint: You get the full pillowtop and gel layer feel in a width that is 15cm narrower than the UK Double, so a compact room keeps its walkway.
- Cool surface for a snug room: Small bedrooms can feel stuffy, and the SensICE cover feels cool when you climb in, which helps if the heating or a sloped ceiling traps warmth.
- Workable for the odd shared night: The Mirapocket springs move independently, so a visiting partner turning over is less likely to disturb you on the occasional night you share.
- Same length as a UK double: The UK small double and the UK Double are the same length, so taller solo sleepers lose width but not legroom compared with sizing up.
This size suits you if...
You sleep alone most nights and like to spread out, your bedroom is too tight for a UK double to leave a clear path to the door, or you're furnishing a spare room where a couple might stay a couple of times a year.
Consider another size if...
You share the bed every night with a partner. We'd recommend the UK double instead, which gives 67.5cm each; we suggest at least 2.6m x 2.8m.

Is the UltraGel CoolTouch 3000 UK small double big enough for a teenager?
For most teenagers who have outgrown a single, yes. The UK small double is 30cm wider than the UK Single and the same length, so there is noticeably more room to turn without needing a bigger bedroom. The soft feel suits side sleepers well, although a teenager who sleeps on their front may find it too yielding.
Will a UK small double UltraGel CoolTouch 3000 fit in a box room?
It depends on your measurements, so measure before you buy. We suggest allowing at least 2.4m x 2.8m for a UK small double, which leaves space to walk round the bed and open the door. If your room is smaller than that, the UK single needs at least 2.1m x 2.8m.
Is the Silentnight UltraGel CoolTouch 3000 small double good for a guest room?
It works well where guests are mostly single visitors with the occasional couple. Across verified owner reviews of soft hybrids like this, cushioning on first contact is what guests notice, and the independent springs help limit disturbance when two people share for a night or two. For regular couple guests, a UK double gives more space each.
Should I get a small double or a king in the UltraGel CoolTouch 3000?
If you share every night and your room allows it, the UK king gives 75cm each and is 10cm longer, which suits taller couples. We suggest at least 2.7m x 2.9m for the UK king. The UK small double is the better choice for one sleeper or a compact room.
What sheets do I need for the UltraGel CoolTouch 3000 in a UK small double?
Look for small double (4ft) fitted sheets with a deep or extra-deep pocket, because this mattress is 37cm deep and standard sheets may not tuck under. A standard double duvet generally gives good coverage on a UK small double without trailing on the floor.
