An award-winner with eco credentials and thoughtful features, it’s designed for shoppers who truly want the best night’s sleep without compromising on values.
First Impressions
The Sofia 1200 Mirapocket catches the eye with its plush finish and subtle, sophisticated design. Slip under the covers and you’ll immediately notice the blend of gentle cushioning and underlying firmness. Unlike traditional memory foam or simple innerspring mattresses, the Sofia utilises Silentnight’s signature Mirapocket system for advanced support and tailored comfort.
Notably, the mattress has earned the prestigious Good Housekeeping Institute’s Getting Greener award, acknowledging its role as an environmentally responsible choice. That’s a real bonus for planet-conscious shoppers.
Key Features
1,200 Mirapocket Springs
The core of the Sofia is the 1,200 individually nested Mirapocket springs. Compared to conventional springs, these adapt independently to the shape and weight of your body. That means support is delivered exactly where you need it, whether you sleep on your back, side, or stomach. Motion transfer is also minimised – so if you share your bed, you won’t be disturbed by your partner’s movements.
Eco Comfort Fibres™
This mattress is filled with Eco Comfort Fibres™, 100% sustainable materials made from recycled plastic. The result is a mattress that’s kinder to the environment and to your wellbeing. The fibres are breathable, keeping the sleeping surface fresh and cool throughout the night. If overheating is a problem for you, this is a big advantage over memory foam options.
Medium-Firm Support
Classed as medium-firm, the Sofia offers a balance between gentle comfort and reliable support. This makes it ideal for most UK sleepers – from growing teenagers to adults of all body types. The firmness is not overpowering, but you’ll feel reassured by the gentle ‘push back’ that helps promote better spinal alignment.
Hypoallergenic Finish
If you suffer from allergies or sensitivities, the hypoallergenic properties of this mattress will give you peace of mind. The breathable cover protects against allergens, providing cleaner, healthier rest.
Size and Availability
The reviewed model is the popular double (150cm x 200cm – 5’ x 6’6”), but Silentnight offers the Sofia range in other UK standard bed sizes, too. Be sure to check current availability, as this best-seller moves quickly and has an estimated delivery time of 2–3 weeks.
5-Year Guarantee and Free Delivery

Benefits of Mirapocket Technology
What sets the Mirapocket spring system apart is its ability to contour exactly to your body. Each spring acts independently, ensuring tailored support and helping to keep your spine aligned. Unlike traditional open-coil mattresses, there are no pressure hotspots. Partner disturbance is minimised, too – so restless nights become a thing of the past.
This is a feature often highlighted in our detailed mattress reviews, and the Sofia ranks highly for motion isolation and consistent comfort across the entire sleep surface.
Sustainable Sleep: Why Eco Comfort Fibres™ Matter
Eco Comfort Fibres™ are Silentnight’s commitment to a greener future. Manufactured using recycled plastic bottles, these soft, springy fibres not only save plastic from landfill but also add real performance value to your mattress. They’re naturally breathable, offer excellent temperature regulation, and are resistant to compression over time.
If you’re passionate about sustainability in the home, the Sofia is among the best mattresses to consider—and you won’t be compromising on comfort.
Comfort and Feel
Sitting around medium-firm on the comfort scale, the Sofia feels substantial without being hard. There’s a welcoming softness as you settle down, with the underlying spring system providing proper support. Whether you sleep alone or with a partner, you’ll notice movement is absorbed—no more being woken by a fidgety sleeper beside you.
The finish of the cover is soft and cool to the touch, thanks to the breathable fibres. The mattress also provides gentle pressure relief, making it suitable for those with joint concerns or people who prefer a less ‘sinky’ feel than memory foam.
How Does the Sofia Compare to Other Mattresses?
When considering alternatives, it’s worth comparing the Silentnight Sofia against other popular models. For in-depth analysis, try our mattress comparisons of leading UK brands.
The Sofia’s main strengths are its price-to-quality ratio, sustainability, and reliable support. Mattresses with similar pocket spring counts and eco credentials often come at a higher price. If you want memory foam, check our memory foam mattress picks for the UK market. But for lovers of traditional, breathable comfort, the Sofia stands out.
Durability and Maintenance
Silentnight are renowned for building long-lasting mattresses, and the Sofia is no exception. Regular rotation (top-to-tail) every three months helps maintain its shape and comfort levels. The reinforced edges ensure good support right up to the mattress sides, reducing the risk of sagging over time.
Unlike many memory foam options, this mattress does not retain heat or odours, and it doesn’t need to be flipped—making it a low-maintenance choice for busy households.
Allergy Protection & Hygiene
The hypoallergenic surface makes the Sofia a smart pick for allergy-prone individuals. The cover’s fresh, breathable design prevents dust mites and other common allergens from settling in. For added protection, pair it with a quality protector like those featured in our Purecare Copper Mattress Protector Review.
Buying Considerations
At £594.95 (RRP £744), the Sofia delivers exceptional value. Free next-day delivery (stock dependent), a 5-year guarantee, and overwhelmingly positive customer feedback make it a standout in the competitive UK mattress market.
Before purchasing, ensure your base is supportive and in good condition. Mattress longevity and comfort can be affected by the foundation you use.
