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.
Layer details from silentnight.co.uk product page, September 2026.
- A shared size that fits real rooms: At 135 x 190cm the UK double sits comfortably in most UK bedrooms, leaving room for bedside tables on both sides where a UK king often wouldn't.
- Cooling for two: The cool-to-touch UltraGel surface runs the full width of the bed, so a warm partner's side stays as cool as yours.
- Less disturbance across 67.5cm each: Two people sharing get 67.5cm each, and the 2000 independent Mirapocket springs limit how much you feel a partner turning over beside you.
- Gentle feel for side sleepers sharing: The medium/soft feel suits couples who both sleep on their side, letting shoulders and hips settle in rather than perching on the surface.
- Easy to dress: Standard double sheets and a 200 x 200cm double duvet are stocked everywhere, though at 33cm deep you'll want deep fitted sheets.
This size suits you if...
You share the bed every night and want the traditional couples' size, your bedroom is around the 2.6m x 2.8m minimum we suggest and a UK king would dominate it, or you sleep alone and want space to spread out, perhaps with a dog or cat claiming a corner.
Consider another size if...
You and your partner both sprawl, or you're regularly joined by children or pets and 67.5cm each feels tight. The UK king is 15cm wider and 10cm longer; allow at least 2.7m x 2.9m and we'd recommend it instead.

Is the UltraGel 2000 double big enough for two adults?
It gives two people sharing 67.5cm each, which is the long-standing UK standard for couples. The 2000 Mirapocket springs move independently, so you feel less of a partner shifting. That said, if either of you is broad-shouldered or a restless sleeper, the UK king's extra 15cm of width is a meaningful upgrade.
What room size do I need for the UltraGel 2000 in a UK double?
We suggest at least 2.6m x 2.8m, with around 3m x 3m the comfortable norm. That allows walking space on both sides and, in most rooms, bedside tables too. This is our guidance rather than Silentnight's, so measure your own layout, including wardrobe and door swing, before committing.
Should I get the UltraGel 2000 in a double or a king?
Choose the UK double if your room is near the 2.6m x 2.8m minimum we suggest, or if you want the easiest bedding to buy. The UK king is 15cm wider and 10cm longer, and needs at least 2.7m x 2.9m. Couples who value sleeping space over floor space should size up.
Will the double fit up narrow stairs in an older terrace?
A 135 x 190cm mattress at 33cm deep is a bulky item, and turning stairs in older terraces or tight new build landings can be awkward. Measure your stairwell, banister clearance and any tight corners before ordering, and check the delivery details with whichever retailer you buy from on this page.
What bedding fits the UltraGel 2000 double?
Standard UK double sheets and a 200 x 200cm double duvet, both widely stocked at every price point. The one catch is depth: at 33cm this is a tall mattress, and regular fitted sheets can pop off the corners, so look for deep or extra-deep fitted sheets.
