Instead of memory foam, the Silentnight Comfort Breathe Plus 1600 uses Airloft fibres, which the brand says are 18x more breathable, sitting over 1,600 springs in total: 1,000 mini springs plus a 600 Mirapocket unit that responds independently to movement. Silentnight describes the feel as medium/soft, a little softer than a medium, so it suits sleepers who want some give rather than a firmer surface. It's 28cm deep and comes in five UK sizes with a 60-night trial and a 5-year guarantee from Silentnight.

Why should you choose this mattress?
If you sleep hot, this is the standout reason to shortlist it. There is no memory foam anywhere in the build: the Airloft comfort layer uses lightweight open fibres that mimic the feel of tiny springs while letting air move through, and the Comfort Breathe fibres below are described as 15x more breathable than standard memory foam. Support comes from a 600 Mirapocket spring unit, where each spring sits in its own pocket and moves independently, which means zoned support and better spinal alignment rather than a one-piece bounce. The hypoallergenic sleep surface is a sensible touch for allergy-prone sleepers. It's a real spend, but the 60-night trial gives you time to be sure.
Key features & layer details
Sleep surface
A naturally hypoallergenic fabric that feels soft against the skin. A gentle starting point for sensitive or allergy-prone sleepers.
Airloft™ comfort layer
A foam alternative made from lightweight, open non-woven fibres, which the brand says is 18x more breathable. It mimics the feel of countless tiny springs, gently contouring to your body and spreading your weight evenly.
1000 Mini springs
A layer of 1,000 mini springs that respond to even slight movements, which means the surface adjusts as you shift in the night. They also add airflow through the middle of the mattress.
Comfort Breathe®
Fibres described as 15x more breathable than standard memory foam. They promote airflow and help regulate temperature, a real plus if you tend to overheat.
600 Mirapocket spring unit
600 pocket springs held in individual fabric pockets, each responding independently to your body. That gives you zoned support and better spinal alignment, and less disturbance from a restless partner.
Protective layer
Disperses pressure from the spring unit across the mattress. In practice, this helps the mattress keep its feel for longer.
Durable case
A soft but hard-wearing outer case designed to keep the mattress comfortable for years.

Best suited for?
Warm sleepers
The Airloft comfort layer and Comfort Breathe fibres are open and breathable with no memory foam, so air can move through and help you stay cooler.
Allergy sufferers
A naturally hypoallergenic sleep surface fabric makes a gentle, soft starting point for anyone who is sensitive or prone to allergies.
Couples
The 600 Mirapocket unit has each spring in its own fabric pocket, so it moves independently and means less disturbance from a restless partner.
Side sleepers
A medium/soft feel, a little softer than medium, plus an Airloft layer that contours gently, gives some welcome give at the shoulders and hips.
Combination sleepers
The 1,000 mini springs respond to even slight movements, so the surface adjusts as you shift position through the night.
This is medium/soft, a little softer than a medium, so it won't suit anyone who needs a firm surface, including heavier sleepers or front sleepers who tend to sink at the hips. And if you love the slow, cradling hug of memory foam, this foam-free build feels springier and more open by design.
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 Comfort Breathe Plus 1600 soft or firm?
Silentnight rates it medium/soft, a little softer than a medium, for sleepers who need some extra give. That tends to suit side sleepers and lighter builds. If you prefer a firmer, more supportive feel, this probably isn't the one.
Does the Comfort Breathe Plus 1600 have memory foam?
No, it's foam-free. Comfort comes from Airloft fibres, which Silentnight says are 18x more breathable than foam, plus Comfort Breathe fibres rated 15x more breathable than standard memory foam. You get contouring without the heat build-up foam can cause.
How many springs does the Comfort Breathe Plus 1600 have?
1,600 in total: 1,000 mini springs in the comfort layers and a 600 Mirapocket spring unit beneath. The pocket springs move independently, which means zoned support and less motion transfer across the bed.
Does the Silentnight Comfort Breathe Plus 1600 come with a trial?
Yes, Silentnight offers a 60-night trial, along with a 5-year guarantee. Delivery is listed at 14 days. That gives you a couple of months to sleep on it at home before committing.
How much does the Comfort Breathe Plus 1600 cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It comes in UK Single, Small Double, Double, King and Super King. It's a mid-range spend, and the breathable foam-free build is the main thing you're paying for.
