Product information

This mattress offers comfort and a luxury feel, giving you the ideal place to recoup from a tiring day. With the Miracoil spring system that boasts continuous open spring technology in three zones, the springs form a coil shape that provides a more acute response to pressure. A cushion top quilted finish offers relaxing comfort.

Paired with a polyester filling, the support system runs through the entire length and width of the mattress. This system maximises the supportive sleep space for a more comfortable night’s sleep.

This mattress has a higher spring count than its comparable year-round model.

Q & As

Silentnight Special Ortho Miracoil Mattress, Kingsize 4.3 5 3 3
Great mattress Really great mattress firm and supportive try before you buy recommend 20 September 2014
Comfortable Nearly Perfect Med/ Firm to Frim Mattress Full Spinal support surgery left me looking for a good supportive mattress and having originally decided on a JL Ortho range I impulse purchased this King Size Silent Night mattress in the summer clearance, and in my opinion it provides good overall medium / firm to firm support, with a generously padded top layer. The only thing that let's this mattress down is the lack of side support meaning it's easy to 'roll off' if you get to close to the edges, which ultimately means a reduced sleeping area. Out of 10 I'd give it 7 or 8. It's comfy and supportive (except for the squishy edges). 19 August 2014
When located, proved a good buy The advice on the website is to try it, so off I went to Kingston town. They did not have it in stock, and weren't going to. A full half hour of flapping failed to locate any other store which had it in the region, so we had to order blind from the website and consider the horror of trying to send it back. Failed to spot the collect option for old mattress, so had to add this in to the order later. When it arrived it had a scary depth (35cm+?) but is certainly comfortable- improved by a mattress cover. However it definitely needs extra king size sheets to fit the higher mattress.Compared with other prices, at £240 this was a real bargain. So overall pretty happy as long as do not roll out of bed. 14 January 2014
