Assessed from Silentnight's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This mattress makes sense if you want hybrid support without a hefty price. The Mirapocket springs are individually responsive and zoned, which means firmer support where your body is heaviest and edge-to-edge stability when you sit or sleep near the side. The Eco Comfort Fibres and 3D fabric layer is designed to move air through the mattress, so if you tend to run warm it should feel less stuffy than dense foam. The hypoallergenic soft-knit surface is a small but genuine plus for allergy-prone sleepers. Yes, it's currently listed in a UK Single only, but for a child's room, guest bed or a solo sleeper who likes a medium/firm feel, it covers the essentials well.
Key Features & what's inside
- Sleep surface. A soft-knit hypoallergenic fabric top, which means a cosy first impression and a sensible choice if dust or allergens bother you.
- Eco Comfort layer. Eco Comfort Fibres and 3D fabric form a breathable comfort layer that helps regulate your temperature through the night. If you're a hot sleeper, this is the part working in your favour.
- Support system. 1000 individually responsive Mirapocket springs with zoned support respond to your movements and support you edge to edge. In practice that means less roll-off at the sides and support matched to different parts of your body.

Who's it NOT for?
If you sleep on your side and are lightweight, the medium/firm feel may press a little too much on hips and shoulders. Couples should look elsewhere for now, as it's listed in a UK Single only. And if you love a deep, sink-in plush surface, this isn't built for that.

Is the Silentnight Just Breathe Eco Comfort Hybrid firm or medium?
Silentnight describes it as medium/firm on its product page, so it leans supportive rather than plush. Some retailer listings label it simply as firm, but the brand's own wording is the better guide.
How many springs does the Just Breathe Eco Comfort Hybrid have?
It has 1000 individually responsive Mirapocket pocket springs with zoned support, which means the springs move independently and support you right to the edges of the mattress.
Does the Silentnight Just Breathe Hybrid come with a trial and guarantee?
Yes. Silentnight offers a 365-night trial and a 10-year guarantee, so you have a full year to decide whether it suits you.
How is the Silentnight Just Breathe Hybrid delivered?
It arrives rolled to your door, with delivery within 48 hours Monday to Friday, excluding Bank Holidays. Being rolled makes it easier to get up stairs and into the bedroom.
Is the Just Breathe Eco Comfort Hybrid good for hot sleepers?
It's designed with hot sleepers in mind. The Eco Comfort Fibres and 3D fabric layer is built to be breathable and help regulate your temperature through the night, which should feel noticeably airier than an all-foam design.
