Why should you choose this mattress?
The main appeal here is comfort with cooling built in. The gel infused top layer is designed to respond to your movements and draw heat away, which means hot sleepers who still want a soft feel don't have to choose between the two. Underneath, 2000 pocket springs work independently, so your body gets support where it needs it and the zoned design is aimed at keeping your spine aligned. The boxtop adds a plush, even layer of pressure relief across the surface. Yes, the medium soft feel won't suit everyone, but for side sleepers and anyone who finds firmer mattresses uncomfortable on hips and shoulders, that softness is the point. The 60-night trial gives you time to be sure.
Key features & layer details
UltraGel comfort layer
A gel infused layer that responds as you move, with cooling foam designed to chill and relax your body. In practice, this means less of the heat build-up you can get with standard foam.
Boxtop
A sumptuous boxtop with advanced gel foam that spreads pressure and bodyweight evenly, which means fewer pressure points at your hips and shoulders. It adapts as you change position through the night.
Mirapocket springs
2000 Mirapocket springs, each in its own fabric pocket, so each one responds to your body independently. The zoned support is scientifically proven, according to Silentnight, to improve spinal alignment and posture.

Best suited for?
Side sleepers
The medium soft feel and gel foam boxtop spread pressure evenly, which means fewer pressure points at the hips and shoulders when you lie on your side.
Warm sleepers
A gel infused top layer is designed to draw heat away, so you get a soft feel without the heat build-up of standard foam.
Combination sleepers
The boxtop layer adapts as you change position through the night, while the gel layer responds to your movements as you turn.
Couples
With 2000 pocket springs each working independently in its own fabric pocket, each of you gets support where your body needs it.
Lighter sleepers
A medium soft feel with a plush boxtop gives lighter bodies the chance to sink in comfortably, with a 60-night trial to confirm it.
This is a medium soft mattress, so if you prefer a firm, supportive surface, or you're a heavier sleeper who tends to sink through softer layers, it's probably not the right fit. Stomach sleepers, who generally need firmer support to keep hips level, may also find it a little too yielding.
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.

FAQ's
Is the Silentnight UltraGel 2000 soft or firm?
Silentnight describes it as medium soft, a little softer than a medium, for sleepers who need a little extra give. It suits side sleepers and anyone who finds firmer mattresses press on hips and shoulders, although if you prefer a firm feel, this might not be the best choice.
Does the Silentnight UltraGel 2000 sleep cool?
It's designed to. The top layer combines gel infused foam with cooling foam intended to chill and relax your body, and the boxtop uses advanced gel foam too. If you tend to overheat on all-foam mattresses, the pocket sprung core also helps air move through the mattress.
How deep is the Silentnight UltraGel 2000 mattress?
It's 33cm deep, which is on the taller side thanks to the boxtop construction. Slightly deeper fitted sheets are worth checking for, as standard ones can be a snug fit on a mattress this height.
What guarantee and trial does the Silentnight UltraGel 2000 come with?
Silentnight offers a 60-night trial and a 5-year guarantee, with delivery listed at 14 days. The trial means you can sleep on it at home before committing, which is reassuring given the softer-than-average feel.
What sizes does the Silentnight UltraGel 2000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King.
