Layer Details
- Cool-to-touch sleep surface. SensICE fabric gives an instant cooling effect against your skin, which means you feel a pleasant chill the moment you get in. It draws heat away from your body for a cooler night's sleep.
- Gel infused comfort layer. A responsive gel infused layer that reacts to your movements. As you shift position through the night, it adapts with you rather than leaving you to sink into one spot.
- Breathable foam. Silentnight describes this foam as 5X more breathable than memory foam, which means heat has somewhere to go instead of gathering beneath you. It works alongside the gel layer to keep the sleep surface feeling fresh.
- Plush pillowtop. A plush pillowtop adds a softer, cushioned feel at the surface for soothing relief. It takes a little of the edge off the firm support beneath.
- Pocket spring support system. 2000 Mirapocket springs combine with 1000 mini springs, giving pressure relief that adapts to your shape. Because each spring moves independently, a restless partner is less likely to disturb you.

- Cooling for two: Two people side by side generate more heat, and the SensICE surface with breathable foam beneath is designed to draw that warmth away rather than let it gather.
- Quieter nights at close quarters: With 67.5cm each you lie nearer your partner than on a UK king, so independently moving springs help stop one person's turning from reaching the other.
- Space left for the rest of the room: At 4ft 6in x 6ft 3in, the UK double is more likely than a UK king to leave room for a bedside table each side.
- A sensible guest room choice: Visiting couples who sleep on their backs or fronts should find the firm support comfortable, and double sheets are easy to buy for a spare room.
This size suits you if...
You share the bed every night in a typical UK bedroom and still want a bedside table on each side, or you're kitting out a spare room for couples who come to stay. It also fits if one of you runs hot and you both prefer a firm feel.
Consider another size if...
One of you is tall or you both sprawl at night. We'd recommend the UK king instead, which gives 75cm each; allow at least 2.7m x 2.9m.

Is the Silentnight UltraGel CoolTouch 3000 Firm double wide enough for two?
For most couples, yes. The UK double gives you 67.5cm each, which is 7.5cm less each than the UK king. Because the springs move independently, a partner shifting position is less likely to disturb you, which helps when you're sleeping this close together.
Will two people sleep hot on the UltraGel CoolTouch 3000 in a double?
Sharing a UK double keeps two bodies close, so heat can build between you. The cool-to-touch SensICE fabric gives an instant chill, and Silentnight says the foam is 5X more breathable than memory foam, which means warmth has somewhere to go instead of settling under you both.
What size bedroom do I need for a UK double UltraGel CoolTouch 3000 Firm?
We suggest at least 2.6m x 2.8m for the UK double, although a room closer to 3m x 3m gives you easier space to walk round the bed and open wardrobe doors. If you want bedside tables either side, measure before buying.
UltraGel CoolTouch 3000 Firm double or king for a couple?
The UK double is 15cm narrower and 10cm shorter than the UK king. Choose the UK double if your room is on the smaller side. Choose the UK king if one of you is tall or you want more personal space, and allow at least 2.7m x 2.9m for it.
Is the UltraGel CoolTouch 3000 Firm double a good choice for a guest room?
It can be, if your guests tend to sleep on their backs or fronts. Lightweight side sleepers may find it a little firm. The UK double gives visiting couples room to share, and double bedding is widely available, so dressing a spare room is straightforward.
