Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes most sense if you sleep warm. The UltraGel surface is designed to feel cool the moment you touch it, and the gel-infused layer beneath is, according to Silentnight, five times more breathable than standard memory foam. The 2000 Mirapocket springs work independently, which means less motion transfer if you share a bed and zoned support that Silentnight says is scientifically proven to improve spinal alignment. The medium/soft feel suits side sleepers and anyone who likes a bit of sink. Yes, £730 upwards is a real spend, but you're getting a deep 33cm hybrid build with a 60-night trial to test it properly.
Key Features & what's inside
- 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.

Who's it NOT for?
If you prefer a firm, supportive feel, or you're a heavier back or stomach sleeper who needs to stay lifted on the surface, the medium/soft feel here may let you sink further than is comfortable. The 33cm depth is also worth checking against your fitted sheets, as standard-depth bedding can struggle.

Is the Silentnight UltraGel 2000 good for hot sleepers?
It's built around that idea. The cool-to-touch surface gives an instant cooling effect through hyper-conductive fabric technology, and the gel-infused layer beneath is described by Silentnight as five times more breathable than standard memory foam. If overheating is your main complaint, this design directly targets it.
How firm is the Silentnight UltraGel 2000 Pocket Cooltouch?
Silentnight rates it as medium/soft. That gentler feel suits side sleepers and lighter builds well, although if you like a firmer, more supportive surface this probably isn't the one for you.
Does the Silentnight UltraGel 2000 come with a trial?
Yes, Silentnight offers a 60-night trial on this mattress, along with a 5-year guarantee. Delivery is listed at 14 days. Terms can differ if you buy through a retailer rather than Silentnight directly, so check before you order.
How deep is the Silentnight UltraGel 2000 mattress?
It's 33cm deep, which is a genuinely tall mattress. That depth gives it a substantial feel on the bed, but you may need deep or extra-deep fitted sheets rather than standard ones.
What sizes does the Silentnight UltraGel 2000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £730 to £1,380 depending on the size you choose.
