Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose this mattress if temperature is your main worry. The Comfort Breathe fibres are designed to promote airflow rather than trap warmth the way traditional memory foam can, which means you should feel noticeably less clammy through the night. The 2000 Mirapocket springs provide zoned support and help with spinal alignment, useful if you and a partner are different weights, as each side responds separately. Silentnight also backs it with a 60-night trial and a 5-year guarantee, so you have a proper window to decide at home rather than in a showroom. Yes, it sits at the pricier end of Silentnight's range, but the spring count and breathability tech go some way to justifying that.
Key Features & what's inside
- Sleep Surface. A naturally hypoallergenic fabric that sits directly against your bedding. It's soft and gentle on the skin, a small comfort if you have sensitive skin or allergies.
- Comfort Breathe®. Silentnight describes these fibres as 15x more breathable than standard memory foam, promoting airflow and regulating temperature. In practice, that means less of the heat build-up hot sleepers dread.
- 2000 Mirapocket Springs. Each of the 2000 springs sits in its own pocket and responds independently to your movements. That gives zoned support and better spinal alignment, and it also limits how much you feel a partner moving.
- Protective Layer. This layer disperses pressure from the spring unit across the mattress. The idea is a longer working life, as no single area takes all the strain.
- Durable Case. A soft but durable outer case designed to keep the mattress comfortable for years. It holds everything together rather than adding a distinct feel of its own.

Who's it NOT for?
If you prefer a properly firm mattress, this medium feel may sit a little soft for you, particularly if you're a heavier back or stomach sleeper who needs more pushback. And if you love the slow, cradling sink of memory foam, the breathable fibre layer here feels springier and less enveloping.

Is the Silentnight Comfort Breathe 2000 good for hot sleepers?
It's built with hot sleepers in mind. The Comfort Breathe fibre layer is described by Silentnight as 15x more breathable than standard memory foam, promoting airflow and helping regulate temperature through the night rather than trapping heat against your body.
How firm is the Silentnight Comfort Breathe 2000?
Silentnight rates it as medium on its own product page. That suits most sleepers, especially side and combination sleepers, although anyone who likes a firm, supportive surface may find it slightly too giving.
Does the Silentnight Comfort Breathe 2000 come with a trial?
Yes. Silentnight offers a 60-night trial, so you can sleep on it at home before committing, plus a 5-year guarantee. Delivery is listed at 14 days.
What sizes does the Silentnight Comfort Breathe 2000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King. Prices range from £565 to £828 depending on the size you choose.
How deep is the Silentnight Comfort Breathe 2000 mattress?
It's 31cm deep, a fairly substantial profile. Worth checking your fitted sheets before it arrives, as shallower sheets can struggle with a mattress of this depth.
