In the Silentnight Comfort Breathe 2000, the Comfort Breathe fibres are, per Silentnight, 15x more breathable than standard memory foam, which means heat moves away from your body rather than building up under you. Beneath that sit 2000 Mirapocket springs that respond independently to movement, so you get support where your body actually needs it. At 31cm deep it's a substantial mattress, and it comes in five UK sizes from Single to Super King. A sensible pick for hot sleepers who want spring support rather than an all-foam feel.

Why should you choose this mattress?
Temperature is the headline here. If you regularly wake up too warm, the Comfort Breathe fibre layer is designed to promote airflow and regulate temperature, and it replaces the heat-retaining memory foam you'd find in many rivals. The 2000 individual Mirapocket springs offer zoned support and help with spinal alignment, which means less of that roll-together feeling if you share a bed. Silentnight backs it with a 60-night trial and a 5-year guarantee, and the sleep surface uses naturally hypoallergenic fabric, a small but genuine plus for allergy-prone sleepers. It's an investment, but the depth and construction help justify that.
Key features & layer details
Sleep surface
A naturally hypoallergenic fabric that's soft against the skin. A gentle starting point, particularly if allergies bother you at night.
Comfort Breathe®
These fibres are 15x more breathable than standard memory foam, which means air moves through rather than trapping heat. If you're a hot sleeper, this is the layer doing the heavy lifting.
2000 Mirapocket springs
Each spring sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it limits motion transfer between partners.
Protective Layer
This layer disperses pressure from the spring unit across the mattress. In practice, that should help the mattress last longer before it starts to sag.
Durable case
A soft, hardwearing outer case designed to keep the mattress comfortable for years to come.

Best suited for?
Warm sleepers
The Comfort Breathe fibres are 15x more breathable than standard memory foam, per Silentnight, so heat moves away from your body instead of building up.
Couples
Each of the 2000 Mirapocket springs sits in its own pocket and responds independently, which limits motion transfer so you feel less of your partner's movements.
Allergy sufferers
The sleep surface uses a naturally hypoallergenic fabric that is soft against the skin, which makes it a gentle choice if allergies bother you at night.
Combination sleepers
Independent pocket springs respond to movement and give zoned support, so the mattress keeps up as you change position through the night.
Back sleepers
The medium feel and zoned support from the Mirapocket springs help keep your spine aligned, giving a supportive spring feel rather than an all-foam sink.
This is a medium feel, so if you specifically want a very firm mattress, or you're a lightweight side sleeper who prefers something noticeably softer, it may not suit. It's also a sprung mattress, so anyone after that slow-sinking, all-foam hug should look elsewhere.
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
How firm is the Silentnight Comfort Breathe 2000 mattress?
Silentnight rates it as medium. That suits most back and side sleepers, although lightweight side sleepers may find it slightly firmer than they'd like, and heavier stomach sleepers might prefer something firmer.
Is the Silentnight Comfort Breathe 2000 good for hot sleepers?
Yes, this is its main strength. The Comfort Breathe fibre layer is 15x more breathable than standard memory foam according to Silentnight, promoting airflow and regulating temperature rather than trapping heat.
Does the Silentnight Comfort Breathe 2000 come with a trial and guarantee?
Silentnight offers a 60-night trial and a 5-year guarantee on this mattress, with delivery listed at 14 days. That gives you a couple of months to decide whether the medium feel suits you.
