Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
If you're a hot sleeper, this is one to shortlist. The UltraGel™ cool-to-touch surface gives an instant cooling effect, and the gel-infused layer beneath is described by Silentnight as 5x more breathable than standard memory foam, which means less of that trapped-heat feeling foam mattresses can produce. Underneath, 2000 Mirapocket® springs move independently with zoned support that Silentnight says is scientifically proven to improve spinal alignment. The medium soft feel is genuinely on the softer side, so you get pressure relief around shoulders and hips rather than a firm platform. Yes, the from-price of £649.84 is a real spend, but the 33cm pillowtop build and 60-night trial soften the risk.
Key Features & what's inside
- 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.

Who's it NOT for?
This isn't the mattress for you if you like a firm feel. It's rated medium soft, a little softer than a medium, and the pillowtop adds further cushioning. Heavier sleepers or dedicated back and stomach sleepers who need a firmer surface may find it too forgiving. Pillowtops also can't be flipped, so you're limited to rotation.

Is the Silentnight UltraGel Pocket 2000 soft or firm?
Silentnight rates it as medium soft, a little softer than a medium, for sleepers who need a little extra give. That suits side sleepers and lighter bodies well, although anyone wanting firm support should look elsewhere in the range.
Does the Silentnight UltraGel mattress sleep cool?
Cooling is its main selling point. The SensICE™ cool-to-touch surface gives an instant cooling effect through hyper-conductive fabric, and the gel-infused layer is 5x more breathable than standard memory foam, according to Silentnight. A sensible pick if you regularly wake up too warm.
Does the Silentnight UltraGel Pocket 2000 come with a trial and guarantee?
Yes. Silentnight's own site lists a 60-night trial and a 5-year guarantee, with delivery in 14 days. If you buy through a retailer, check their terms, as they can differ.
How deep is the Silentnight UltraGel Pocket 2000 Pillowtop mattress?
It's 33cm deep, which is a tall profile thanks to the pillowtop. That can make fitted sheets a squeeze, so check your bedding suits a deep mattress before you buy.
What sizes does the Silentnight UltraGel Pocket 2000 come in?
It's available in UK Single, Small Double, Double, King and Super King, with prices running from £649 to £1,222 depending on size.
