Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
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 at £519 to £1,009 depending on size, but the depth and construction help justify that.
Key Features & what's inside
- 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.

Who's it NOT for?
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.

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.
How deep is the Silentnight Comfort Breathe 2000 mattress?
It's 31cm deep, which is a substantial build. Do check your fitted sheets will stretch over a mattress this deep, as some standard sheets won't.
What sizes does the Silentnight Comfort Breathe 2000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices run from £519 to £1,009 depending on the size you choose.
