Design and Build Quality
The Silentnight Just Breathe Eco Comfort Hybrid Mattress blends traditional and modern sleep technologies. Its hybrid design combines responsive Mirapocket springs with two layers of advanced comfort filling: the eco comfort fibre layer and a memory foam comfort top. These are all encased in a breathable, quilted cover that feels as good as it looks.
Hybrid construction is a great choice if you want balanced support, pressure relief, and motion isolation. Sprung mattresses deliver bounce and edge support; memory foam provides contouring; and the eco fibre layer enhances airflow and sustainability.
Eco Comfort Layer: Sustainable Innovation
A key feature is the use of Silentnight’s Eco Comfort Fibres. They’re made from recycled plastic bottles, giving discarded plastics a useful second life and preventing landfill waste. This also helps to reduce the carbon footprint of your bedtime routine, all without compromising on comfort or firmness.
The Eco Comfort layer is highly breathable, ensuring you stay cool through the night—a big plus for hot sleepers and for those put off by the heat-rententive nature of traditional memory foam.
Memory Foam for Pressure Relief
The upper comfort layer is memory foam—chosen for its supportive, pressure-relieving contour. Memory foam adapts gently to your body shape, helping to reduce pressure points and prevent morning aches. This is ideal for people with joint or back pain, or for anyone craving a mattress that ‘hugs’ the body but without excessive sinkage.

Mirapocket Springs: Tailored Support
The core of this mattress is built on Silentnight’s acclaimed Mirapocket spring system. Each pocket spring is individually wrapped, moving independently to respond to your weight and shape. This design helps distribute body weight evenly and minimises ‘roll together’—so partners won’t disturb each other during the night.
With its firmer feel, the Just Breathe Eco Comfort Hybrid is especially suited to sleepers who like a responsive, supportive base rather than something soft. The springs also add a little bounce, which can make moving in bed or getting up easier for anyone with mobility concerns.
Breathability and Temperature Control
One of the standout benefits is its breathability. The quilted cover, eco comfort fibres and open pocket spring structure work together to encourage ventilation. This keeps you cooler and drier throughout the night—a huge win if you’re someone who overheats easily.
This commitment to temperature regulation sets it apart from many traditional memory foam mattresses, which have a tendency to trap heat.
Who Will Love the Silentnight Just Breathe Eco Comfort Hybrid?
This mattress is a strong contender for a variety of sleepers and life stages. You’ll especially benefit if:
- You want a firm mattress with robust support
- You prefer high breathability for a fresh, cool sleep
- You care about environmentally friendly design
- You struggle with back pain and need even weight distribution
- You’re shopping for a guest room, teenager, or student

Firmness and Support
Labeled as ‘firm’, this mattress gives a solid sleeping surface—particularly suitable for back and stomach sleepers. Side sleepers who prefer extra plushness might find it too firm, but many have found the combination of memory foam and pocket springs delivers support where it’s needed most, reducing morning aches.

Motion Isolation—Great for Couples
If you share a bed, motion transfer (the amount you feel your partner tossing and turning) is crucial. The Mirapocket system is designed to isolate movement, so if your partner fidgets or gets up in the night, you’re much less likely to be disturbed. The memory foam layer further dampens vibrations, offering a calmer sleep for both parties.
Edge Support
Edge support is often overlooked, but it’s vital for making full use of your mattress. Thanks to the perimeter springs and reinforced construction, you’ll find little sagging when sitting or lying near the edge—making the Silentnight Just Breathe Eco Comfort Hybrid a practical choice for anyone who gets in and out of bed frequently or prefers to use every inch of their mattress.
Materials and Safety
This mattress is free from harmful chemicals and meets stringent UK flammability standards—something especially important for family buyers or those kitting out children’s rooms. Silentnight’s materials are hypoallergenic, making it suitable for allergy sufferers and those with sensitive skin.
Ease of Set Up and Delivery
The Just Breathe Eco Comfort Hybrid is delivered rolled and boxed for convenience. This makes moving it to your chosen room much easier than traditional full-sized mattresses. Once unpacked, it quickly expands to its full depth—usually within a few hours, although it’s best to allow 24 hours for it to settle completely and any residual odour (off-gassing) to dissipate. For more information about off-gassing, see our Off-Gassing – How Long Will My Mattress Smell? guide.
Care and Maintenance
This is a single-sided mattress, which means it should not be flipped over. However, Silentnight recommend regular rotating (head-to-foot) to promote even wear and longevity. Maintenance is minimal, especially with the built-in cover that resists dust mites and allergens.
To extend the life of your mattress and protect against spills, we always recommend using a quality mattress protector. See our reviews, such as the Dreameasy Luxury Waterproof Mattress Protector.
Value for Money
Currently priced at £394.95 (single), down from the £553.50 RRP, this mattress is positioned at the higher end of the budget market but offers significant value given the layered design and brand reputation. Silentnight often offers superior longevity compared to unbranded alternatives, making it a sound investment over the years.

Customer Reviews and Feedback
Overall customer sentiment is very positive. Users praise the mattress for its supportive firmness, breathability, and the fact that it remains cool throughout the night. Several back pain sufferers report noticeable improvements in morning stiffness and discomfort after switching.
Some lighter side sleepers find the mattress firmer than expected, but this is to be expected for a firm-rated hybrid. The product enjoys consistently high marks for quick delivery, ease of installation, and Silentnight’s reliable UK-based customer service.
