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.

- Leaves room for the furniture: We suggest at least 2.6m x 2.8m for a UK double, which means most main bedrooms can still fit a wardrobe and a bedside table on each side.
- Less disturbance at close quarters: The 2,000 Mirapocket springs move independently, which matters at 67.5cm each because a partner turning over is less likely to jolt you awake.
- A fresher feel for two: Two people under one duvet build up warmth, and the cool-to-touch SensICE surface means the bed feels fresh rather than warm when you both get in.
- Simple to dress: Double duvets are sold everywhere, with a 200 x 200cm duvet the usual fit, although the 37cm depth means you'll need deep fitted sheets.
- A kind spare bed: In a guest room it gives visiting couples a proper shared bed, and the plush pillowtop is forgiving for guests who sleep mostly on their side.
This size suits you if...
You share the bed every night and your room is too snug for a UK king, or you're setting up a guest room for visiting couples who mostly sleep on their side and like a cushioned feel.
Consider another size if...
You're both tall or like to spread out, and already feel cramped sharing. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

Is the UltraGel CoolTouch 3000 UK double wide enough for two side sleepers?
For most side sleepers, yes. A UK double gives you 67.5cm each, and side sleepers tend to take up less width than people who sprawl on their backs. The soft pillowtop also suits that position. If one of you starfishes, the UK king gives 7.5cm more each, which you would notice over a full night.
How much bigger is the Silentnight UltraGel CoolTouch 3000 UK king than the UK double?
The UK king is 15cm wider and 10cm longer than the UK double, giving 75cm each for two sharing, which is 7.5cm more per person. It needs more floor space too: we suggest at least 2.7m x 2.9m for the UK king, against at least 2.6m x 2.8m for the UK double.
Will a UK double UltraGel CoolTouch 3000 fit in a second bedroom with a wardrobe?
Allow at least 2.6m x 2.8m for a UK double, with around 3m x 3m feeling comfortable once drawers and a wardrobe go in. Measure where the doors open, too. If your room falls short, the UK small double is 15cm narrower, and we suggest at least 2.4m x 2.8m for it.
What fitted sheet do I need for the UltraGel CoolTouch 3000 in a UK double?
Buy a double fitted sheet for a 135 x 190cm mattress, but choose a deep or extra-deep version. At 37cm, this mattress is thicker than many, and a standard double sheet may pull off the corners. A 200 x 200cm double duvet is the usual match on top.
Is the UK double UltraGel CoolTouch 3000 long enough for tall sleepers?
The UK double is 190cm long (6ft 3in), the same length as the UK single and UK small double. That suits most adults, but if either of you is tall enough for your feet to reach the end, the UK king and UK super king are both 10cm longer.
