Layer Details
Cool-to-touch sleep surface
The UltraGel™ cool-to-touch layer uses hyper-conductive technology woven into the surface fabric, which means the mattress feels instantly cool when you lie down. It's the feature to care about if overheating regularly wakes you.
Gel-infused layer
This gel-infused foam responds to your movements and is 5x more breathable than standard memory foam, according to Silentnight. In practice, that means the contouring of foam with less of the heat build-up.
Pillowtop
A pillowtop surface adds a plush, cushioned top to the mattress. It gives that sink-in, hotel-bed feel rather than a firmer sleeping surface.
Pocket spring support system
2000 Mirapocket® springs work independently, which means one side of the bed can move without disturbing the other. The zoning is scientifically proven, Silentnight says, to improve spinal alignment and posture.

Key benefits
- Space for two bedside tables: At 135 x 190cm, a UK double usually leaves room for a bedside table on each side, provided your bedroom meets our suggested minimum of 2.6m x 2.8m.
- Less disturbance from a partner: The 2000 Mirapocket springs move independently, which means a restless partner's tossing and turning is less likely to reach your side, even at 67.5cm each.
- Cooler when two people share: Two bodies make more warmth than one, and the cool-to-touch surface with a gel-infused layer beneath is designed to limit that trapped-heat feeling.
- A comfortable guest bed: In a spare room, a UK double sleeps a visiting couple well, and the medium soft pillowtop gives a plush, hotel-style feel most guests settle into easily.
- Bedding is simple to find: Double sheets are sold almost everywhere, though at 33cm deep this pillowtop needs fitted sheets with generous pockets, so check the depth before you buy.
This size suits you if...
You share the bed with a partner and your bedroom sits around our suggested minimum of 2.6m x 2.8m, you want a bedside table either side without the bed filling the room, or you're furnishing a guest room for couples who come to stay.
Consider another size if...
You're both tall or want more personal space, as the UK double is 10cm shorter and 15cm narrower than the UK king. We'd recommend the UK king instead, allowing at least 2.7m x 2.9m.

FAQ's
How much space does each person get on the Silentnight UltraGel Pocket 2000 UK double?
Each of you gets 67.5cm of width on the UK double, and the length is 190cm, or 6ft 3in. That suits most couples of average build. If you'd like a little more room, the UK king gives 75cm each, so the UK double gives 7.5cm less per person.
Will the Silentnight UltraGel UK double fit in a small second bedroom?
We suggest allowing at least 2.6m x 2.8m for a UK double, with around 3m x 3m a more comfortable fit once a wardrobe and drawers go in. If your room is tighter, the UK small double is 15cm narrower and we suggest at least 2.4m x 2.8m for it.
Will I feel my partner move on the UltraGel Pocket 2000 in a double?
Sharing 67.5cm each means you're fairly close, so motion matters more on a UK double than on wider sizes. The 2000 Mirapocket springs work individually, which means movement on one side is less likely to travel across. The soft pillowtop adds cushioning, although very light sleepers may still notice a partner getting in and out.
Silentnight UltraGel UK double or UK king for two hot sleepers?
The cooling surface and gel-infused layer are the same in both sizes. The difference is space: the UK king gives 75cm each against 67.5cm on the UK double, so you have a little more distance between you. If your room allows at least 2.7m x 2.9m, the UK king is the more comfortable choice for two warm sleepers.
Is the UltraGel Pocket 2000 UK double good for one person and a pet?
Yes, for most solo sleepers. The UK double is 45cm wider than the UK single, which leaves room for a dog or cat to claim a corner while you still stretch out. The medium soft pillowtop suits side sleepers well, but heavier sleepers who prefer a firmer surface may find it too forgiving.
