Offering luxury and durability, the award-winning Silentnight Sofia 1200 Mirapocket Mattress provides a truly indulgent sleep experience. This impressive product was awarded Which? Best Buy for 2015 thanks to its high levels of support and comfort combined with its low price tag.

Featuring an advanced Mirapocket spring system, the Sofia 1200 has been expertly designed and manufactured to help you sleep soundly throughout the night. Its pocket springs work independently, minimising any disturbance caused by movement on the other side of the bed. It also has zoned areas that ensure each part of your body gets the support it needs.

Worried about allergies getting in the way of a good night’s rest? The Silentnight Sofia 1200 can help to eliminate this problem. It is treated with Purotex to combat dust mite allergens, making it ideal for allergy and asthma sufferers, and anyone else looking to get a healthier night’s rest.

Covered in a soft, breathable knitted cover, the mattress is 26cm deep and it features stitched handles on the sides. By turning it regularly, you can ensure it continues to provide a restful sleeping surface year after year.

Manufactured in the UK, the Silentnight Sofia 1200 offers the highest levels of quality and craftsmanship. For added peace of mind, it comes with a 5-year guarantee.


Mirapocket Springs

Exclusive to Silentnight, the Mirapocket spring system offers outstanding support and superior spinal alignment. It maximises sleeping space and reduces "roll-together" for less partner disturbance - making it ideal for couples.

Eco Comfort Fibres

Breathable and sustainable fibres that are 100% recyclable give you a fresh and purifying sleep from eco-friendly materials that won’t cost the planet or your pocket. Eco Comfort Fibres have been scientifically proven to keep you cooler while you sleep.

26cm Deep

This mattress is approximately 26cm deep.

Medium Firm Support

Good for people who change sleeping position.

Knitted Cover

This luxurious soft knitted cover is breathable, which helps to keep the sleeper at an even temperature all night long.

Reinforced Edges

The mattress has reinforced edges, so that the full sleep surface can be used. This means more sleeping space - which is usually lost in conventional, less edge-stable mattresses.

No Roll Together

Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.

Turning Handles

Flag-stitched handles are attached to the sides of the mattress to assist in turning or rotating.


Being hypoallergenic, this is the perfect item allergy sufferers - or anyone looking for a healthy night's sleep.


The mattress has fillings on both sides. Double-sided mattresses need to be turned regularly to keep them in good condition.

I should have replaced my old mattress years ago. This one is fantastic: it is firm (which I like) but still has a sense of buoyancy. Both my wife (who found the old mattress uncomfortable) and I immediately had a much better night's sleep. Highly recommended!

We needed a new mattress and we were attracted by the "which" awards received by the silentnight sofia 1200.We have had it for a couple of weeks and for now we are satisfied but please bear in mind:1): the mattress is quite firm -so do not buy it if you like soft-ish ones- however it has definitely improved some back and hip pain.2): I have noticed that it is slightly sagging, so (after 2 weeks) I have turned it up side down (unlike memory foam mattresses, it can be turned). The slight sagging for now does not seem to be affecting the firmness, but I would say that it is a bit too early to express a final judgement. Overall we are happy with the product.
