Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the combination of cooling and support. The gel infused top layer is designed to draw heat away while adjusting to your movements, which means less of that clammy feeling foam mattresses can cause. Beneath it, 2,000 pocket springs work independently, so if your partner turns over you're less likely to feel it. The medium soft feel gives a gentler, more cushioned surface than a standard medium, well suited to side sleepers and lighter bodies. It won't suit everyone: heavier sleepers or those who like a firm bed may find it too forgiving. The 60-night trial gives you a proper chance to decide at home, backed by a 5-year guarantee.
Key Features & what's inside
- UltraGel comfort layer. A gel infused foam layer that adjusts to your body's movements while helping to cool you down, which means pressure relief without the heat build-up plain foam can cause. It also has a degree of bounce back, so you shouldn't feel stuck in one position.
- Mirapocket springs. 2,000 pocket springs that move independently of one another, giving zoned support where your body needs it. Because each spring reacts on its own, movement on one side of the bed is far less likely to disturb the other.

Who's it NOT for?
This is a medium soft mattress, a little softer than a standard medium, so it's unlikely to suit anyone who prefers a firm sleeping surface. Heavier sleepers and dedicated front sleepers, who generally need more resistance to keep the spine level, may find it sinks a little too readily.
Silentnight UltraGel 2000 Pocket Mattress
Is the Silentnight UltraGel 2000 firm or soft?
Silentnight describes it as medium soft, a little softer than a medium, for sleepers who need some extra give. Some retailer listings label it simply as medium, so treat it as sitting on the softer side of medium rather than a true middle-of-the-road feel.
How many springs does the Silentnight UltraGel 2000 have?
It contains 2,000 Mirapocket springs. Each spring moves independently, which means the mattress can offer zoned support and reduce the disturbance you feel when a partner moves during the night.
Does the Silentnight UltraGel 2000 come with a trial and guarantee?
Yes. Silentnight offers a 60-night trial and a 5-year guarantee, so you have two months to decide whether the medium soft feel works for you at home. Terms may differ if you buy through a retailer, so check before ordering.
Is the Silentnight UltraGel 2000 good for hot sleepers?
It's designed with hot sleepers in mind. The top layer is gel infused foam intended to cool you down while it cushions you, and the pocket sprung core allows more airflow than an all-foam design.
How deep is the Silentnight UltraGel 2000 mattress?
It's 31cm deep, which is on the deeper side. That gives a substantial feel, but it's slightly deeper than some fitted sheets allow for, so check your bedding will stretch to fit.
