The Silentnight Thornbury mattress delivers cutting edge comfort with its innovative Mirapocket zoned support system. It has up to 3611 edge-to-edge springs, which spread your weight evenly across the whole mattress, giving you maximum sleep space.
An upgrade of the popular Risborough mattress, the Thornbury provides firm support and is made from high quality hypoallergenic mattress fabric that aids airflow for a cooler sleep. Part of the Affinity range, it features a new and improved TCPP free memory foam comfort layer which gently hugs you to sleep, moulding with the contours of your body for soothing pressure relief. It recovers far quicker than other memory foams, so you won’t be left with a sinking feeling and will find it much easier to get out of bed.
Exclusive Nanoflex™ springs give you personalised comfort across the whole sleep surface. The layer of up to 1500 mini super springs at the top of your mattress, depending on the size, delivers adaptive comfort that’s built to last. Specially designed individual pockets absorb motion and the mattress is topped off with a luxury quilted pillowtop sleep surface.
There’s also a Purotex cover which works to reduce moisture and dust-mite allergens to create a drier, fresher and all-round healthier sleeping environment.
Single sided: Rotate head to toe weekly for the first 3 months, then just once a month.
For your peace of mind, our Bedcover Service Plan lets you rest easy about the looks, comfort and performance of your new mattress, bed or furniture with cover of up to 8 years.

Several of our mattresses are 'double sided' which means that both sides of the mattress are suitable for sleeping on - this feature will be highlighted in the product description.
If your mattress is double sided, we suggest turning your mattress with the same frequency as rotating - so weekly for the first three months and then every month thereafter.
All our mattresses come with a specific guarantee period - this ranges from 1 year to 10 years and will depend on the brand. You can find the guarantee for each mattress listed in the product description on our website.
The spring count for this mattress can be viewed in the product specifications in the overview section.
Our mattresses have been designed to accommodate a variety of different sleepers - therefore we do not specify weight limits for any of our mattresses. If you are concerned about the support that a mattress will be able to offer you, we would suggest visiting your local store to discuss your requirements with our team who will help you find the most suitable mattress.
Most of our mattresses are compatible with all of our bases and bed frames. The product description will state if it is compatible with our Sleepmotion or adjustable bed frames. Please note that if you are choosing a mattress for the top bunk of a child's bed frame, it must be 15cm or less in depth.
Electric blankets can be used with all our mattresses however we do not recommend that they are placed directly on the mattress surface. In addition, using an electric blanket may alter the comfort grade of the mattress depending on the mattress type.
We also recommend following all guidelines and instructions specified by the manufacturer of your electric blanket.
All new mattresses are designed to settle/dip slightly in the areas that you sleep the most. We measure our mattress depths from the top edge to the bottom. Because they're handmade, the depths can vary slightly throughout - especially towards the middle. This is where the luxurious and supportive fillings are more prominent. The layers and fillings are simply responding to pressure point areas and providing support where you need it. While a little settlement is no cause for concern, there are ways you can minimize any further dipping:
