The Silentnight UltraGel Pocket 2000 Pillowtop Cool Mattress is rated medium soft, a little softer than a medium for sleepers who need extra give, so it suits side sleepers and lighter bodies better than those who like a firm, planted feel. At 33cm deep with a pillowtop finish, it has a plush, hotel-style profile, and it comes in five UK sizes. Silentnight backs it with a 60-night trial and a 5-year guarantee.

Why should you choose this mattress?
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, it's a real spend, but the 33cm pillowtop build and 60-night trial soften the risk.
Key features & 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.

Best suited for?
Side sleepers
The medium soft feel and pillowtop top layer give pressure relief around shoulders and hips, so your body can sink in rather than rest on a firm platform.
Warm sleepers
A cool-to-touch surface and a gel-infused layer that is 5x more breathable than standard memory foam, according to Silentnight, mean less trapped heat overnight.
Lighter sleepers
Lighter bodies suit the medium soft rating, which is a little softer than a medium, so there is enough give to feel properly cushioned.
Couples
The 2000 Mirapocket springs work independently, which means one side of the bed can move without disturbing the other person.
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.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.
