Why should you choose this mattress?
Soft mattresses often run warm because you sink further into the comfort layers, so the cooling design here matters. The SensICE fabric feels cool to the touch when you first get in, and Silentnight says the foam beneath is 5X more breathable than memory foam, which means less heat building up around you overnight. Underneath, the 2,000 Mirapocket springs move independently, so a restless partner is less likely to wake you. Yes, it's a real spend for a soft mattress, but you're getting a 37cm hybrid with a pillowtop, a 60-night trial to change your mind, and a 5 year guarantee behind it.
Key features & layer details
Cool-to-touch sleep surface
The SensICE fabric gives an instant cooling effect against your skin, drawing heat away from your body. In practice, that means the bed feels cool when you climb in rather than warming up straight away.
Gel infused comfort layer
A responsive gel infused layer that adapts as you move and bounces back. You get cushioning without the slow, stuck-in feeling some soft foams can have.
Extremely breathable foam
Silentnight states this foam is 5X more breathable than memory foam, working alongside the gel layer. Air moves through it more freely, which helps stop heat gathering under you overnight.
Plush pillowtop
A boxtop layer that adds a soft, soothing top surface. It's a big part of why this mattress feels so cushioned on first contact.
Spring support system
2,000 Mirapocket springs combine with 1,000 mini springs for pressure relief and undisturbed sleep. Each spring moves on its own, so you feel supported where you need it and less of your partner's movement.

Best suited for?
Side sleepers
The 37cm depth and plush pillowtop give a cushioned surface that lets shoulders and hips sink in a little, which suits sleeping on your side.
Warm sleepers
SensICE fabric feels cool to the touch and the foam is said to be 5X more breathable than memory foam, so less heat builds overnight.
Couples
Each of the 2,000 Mirapocket springs moves independently, which means you should feel less of your partner's movement when they turn over during the night.
Combination sleepers
The responsive gel infused layer adapts as you move and bounces back, so changing position doesn't leave you feeling stuck in slow, heavy foam.
This is a genuinely soft mattress, so it's a poor match if you sleep mainly on your front or need a firmer surface for your back. Heavier sleepers may sink further into the pillowtop than is comfortable. And at 37cm deep, standard fitted sheets may struggle: you'll likely need deep or extra-deep bedding.
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 CoolTouch 3000 good for hot sleepers?
It's designed with hot sleepers in mind. The SensICE surface feels cool to the touch, and Silentnight says the foam beneath is 5X more breathable than memory foam, which means less heat trapped around your body. No mattress can guarantee a cool night, but the whole build leans that way.
How many springs does the UltraGel CoolTouch 3000 have?
It has 3,000 springs in total: 2,000 Mirapocket pocket springs plus 1,000 mini springs. Pocket springs move independently, which means better pressure relief and less disturbance when a partner turns over.
How deep is the Silentnight UltraGel CoolTouch 3000?
It's 37cm deep, which is taller than most mattresses thanks to the plush pillowtop. That extra height feels luxurious, but you'll probably need deep fitted sheets to get a proper fit.
Does the Silentnight UltraGel CoolTouch 3000 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. If you buy from a retailer rather than Silentnight directly, check their terms, as they can differ.
What sizes does the UltraGel CoolTouch 3000 come in?
It's available in UK Single, Small Double, Double, King and Super King.
