In the Silentnight Comfort Breathe 1000, the Comfort Breathe fibre layer is, according to Silentnight, 15x more breathable than standard memory foam, which means heat escapes rather than building up around you overnight. Beneath that, 1000 Mirapocket springs move independently, so you get zoned support and less disturbance from a restless partner. It's 24cm deep and sits at the affordable end of the pocket sprung market. It comes with a 60-night trial and a 5-year guarantee from Silentnight, and it's available in five UK sizes from Single to Super King.

Why should you choose this mattress?
If you're a hot sleeper on a budget, this is the sort of mattress designed with you in mind. The Comfort Breathe layer uses breathable fibres rather than memory foam, which means airflow and temperature regulation instead of that sink-in warmth foam can trap. The 1000 Mirapocket springs respond individually to your body, giving zoned support and better spinal alignment than a basic open coil unit. The sleep surface is naturally hypoallergenic and the mattress is dust mite resistant, a genuine plus for allergy sufferers. It's a simple construction, but the 60-night trial gives you a fair window to decide at home.
Key features & layer details
Sleep Surface
A naturally hypoallergenic 100% polyester fabric that's soft and gentle on the skin. A sensible choice if allergies tend to disturb your sleep.
Comfort Breathe®
Silentnight states these fibres are 15x more breathable than standard memory foam, promoting airflow and regulating temperature. In practice, that means less overnight heat build-up, which hot sleepers will appreciate.
1000 Mirapocket Spring Unit
1000 Mirapocket springs respond individually to your body's movements, which means support where you need it rather than a one-size-fits-all push back. The zoning helps keep your spine aligned.
Protective Layer
This layer disperses pressure from the spring unit across the mattress. The aim is a longer usable life, as it stops the springs wearing through to the comfort layers above.
Durable Case
A soft, durable outer case that holds everything together and helps the mattress stay comfortable over the years.

Best suited for?
Warm sleepers
The Comfort Breathe fibre layer is described as 15x more breathable than standard memory foam, which means heat escapes rather than building up overnight.
Budget buyers
Sitting at the affordable end of the pocket sprung market, it gives you 1000 Mirapocket springs and a five-layer build without a premium outlay.
Allergy sufferers
A naturally hypoallergenic polyester sleep surface and dust mite resistance make this a sensible pick if allergies tend to disturb your sleep.
Couples
Each of the 1000 Mirapocket springs moves independently, so you get zoned support and less disturbance when a restless partner shifts beside you.
If you prefer a soft, cushioned feel, the medium/firm tension here may feel a little unforgiving, and lightweight side sleepers in particular might find it too firm at the shoulders and hips. If you prefer that slow, hugging memory foam sensation, this might not be the best choice either, as it uses breathable fibre instead.

FAQ's
Is the Silentnight Comfort Breathe 1000 good for hot sleepers?
Yes, that's arguably its main strength. The Comfort Breathe fibre layer is, per Silentnight, 15x more breathable than standard memory foam, promoting airflow and regulating temperature rather than trapping heat the way foam can.
How firm is the Silentnight Comfort Breathe 1000?
Silentnight rates it as medium/firm. That suits most back and front sleepers, although lightweight side sleepers may find it slightly too firm for comfortable pressure relief at the shoulders and hips.
Does the Silentnight Comfort Breathe 1000 come with a trial and guarantee?
Yes. Silentnight offers a 60-night trial, so you can test it at home before committing fully, and the mattress is covered by a 5-year guarantee. Delivery is quoted at 14 days.
How deep is the Silentnight Comfort Breathe 1000?
It's 24cm deep. That's a fairly standard depth, so most fitted sheets should work without any trouble, though it's shallower than some premium hybrid designs.
What sizes does the Silentnight Comfort Breathe 1000 come in?
Five UK sizes: Single, Small Double, Double, King and Super King.
