Silentnight Miracoil3 Ortho King Mattress


Silentnight's Miracoil® 3 is the most popular sleep range in the UK. It gives you zoned support that loves your back, pressure relief for a perfect night's sleep, edge to edge support for extra sleep space and individual sleep zones for undisturbed sleep.

Perfect if you or your partner:

  • Don't have any particular sleep problems
  • Prefer a medium to firm feel

All Silentnight Miracoil® 3 beds also feature a comfortable top layer that is hypoallergenic for a healthy night's sleep.

Perfect if you or your partner:

  • Enjoy that fresh bed feeling every day
  • Are concerned about allergies and dustmites

Zoned Support

A busy day can leave you feeling tired, stressed and shorter! Your spine is squashed by up to 2cm each day and how you sleep at night affects how well it will recover. Silentnight's Miracoil® springs support the different areas of the body in different ways. They are strong around your hips, where half your body weight is, and they are gentle and supportive around areas that need cushioning, like your shoulders. They've tested all different shapes, sizes and sleeper types and the result is always the same; these three different support zones let your body relax into the perfect stress-free position. This means your spine can completely recover overnight, so you can walk taller the next morning.

The Miracoil® 3 spring system offers support for mainly the lower back. For 7 targeted support zones including an extra cushioning layer why not try a Silentnight Miracoil® 7 Mattress or Divan set.

Pressure Relief

Feeling the pressure? Tossing and turning, aches and pains, waking up with parts of your body numb? These are all signs that pressure points are causing restless sleep. Because your body is not uniform, certain areas like the shoulders and hips will experience pressure while you sleep. Silentnight's unique Miracoil® spring system is designed to spread body weight evenly, so there are no uncomfortable pressure hotspots and you get an undisturbed night's sleep.

No Roll Together

If you or your partner are one of the 50% of people who wake up in the night, then sharing a bed might not be much fun. Silentnight's unique Miracoil® spring system runs from head to toe, so any movement runs up and down the mattress, not across. This means that you and your partner have individual sleep zones, you won't disturb each other and you won't roll together. So you can both enjoy deep and refreshing sleep, whatever your shape or size.

More Sleep Space

The more space you have in bed, the better you sleep. Because Silentnight's unique Miracoil® springs don't wobble, collapse or bulge, they give you support across the whole surface of your mattress. This means you can sleep comfortably right to the edge without rolling off; reclaiming space lost in an ordinary mattress. In fact, sleeping in a Silentnight bed can give you an extra 25% more personal sleep space to enjoy.


Hypoallergenic and dustmite resistant

No Need to Turn

Easy care mattress- no need to turn, simply rotate

Purotex® Friendly Bacteria

Purotex® is the only 100% naturally friendly bacteria which reduces mould and moisture keeping dust-mites at bay and reducing allergens for a drier, fresher, healthier mattress throughout.

Silentnight Beds

Silentnight Beds is the UK's largest manufacturer of branded beds for the home. At Silentnight they understand that a good night's sleep isn't just about getting to sleep or staying asleep. It's the quality of what happens to your body while you're asleep that makes all the difference to how you feel the next day. They are also famous for the Hippo and Duck characters, first created to demonstrate the unique "No Roll Together" properties of a Silentnight bed.

Rated 4.5 out of 5 by 8 reviewers.
Rated 5 out of 5 by Hugely impressed Disclaimer: I work for Asda, but please don't let that affect your perception of this review. I wasn't expecting much from a mattress at this price, but couldn't have been more wrong. It's easily as comfortable as the ridiculously expensive one I was recommended to get to help with my bad neck. It's got some memory foam in it, but it doesn't make me hot and sweaty like my old full memory foam mattress. I'm very pleased. 12 November 2013
Rated 5 out of 5 by Soooooo comfy This is a very comfy mattress and once I get a decent bed base im sure I will have many wonderful nights sleep 11 July 2011
Rated 5 out of 5 by Good firm mattress Seems like a good buy, albeit it a tight squeeze for the ikea bed frame. Fantastic delivery service though cannot fault it. 10 February 2014
Rated 2 out of 5 by not the best Ordered this as we had what we thought was the same very comfortable mattress,this by comparison is extremely hard and uncomfortable.It might be ok for younger bones but as a couple in their 40's not for us,we had to buy a memory foam topper,i wouldn't recommend buying a matress from internet always go to a store and try before you buy. 23 January 2015
Rated 4 out of 5 by Very supportive We have found the mattresses very supportive. We both suffer with bad backs and this mattress is defo helping. It is however VERY firm and even though we have put a foam topper on it I still find it hurts my hip when I sleep on my side (seems to be the thing for women). 23 March 2014
Rated 5 out of 5 by comfortable Very comfortable I had a bad back before and only had this mattresses a week and my back is much better 07 February 2015
Rated 5 out of 5 by excellent comfort Very comfortable and surprisingly light compared to old mattress. 13 May 2014
