Silentnight Miracoil 3 Mattress with Memory Foam - Double


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

Body Moulding Memory Foam

Memory Foam works with your natural body heat, it moulds to your curves to relieve uncomfortable pressure points. Body moulding memory foam spreads rather than sinks, has quicker recovery and offers more stable support; so it gives you great pressure relief with no loss of movement or support.

Perfect if you or your partner:

  • Occasionally have neck, shoulder or back problems
  • Love body moulding comfort

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 sytem 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.

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 4.8 out of 5 by 8 reviewers.
Rated 5 out of 5 by A really comfortable sleep every night This mattress was firmer than I expected, given that the description said medium to firm and the specification list said medium. I was a little unsure about ordering it in case it wasn't firm enough, but when it arrived I was surprised just how firm it felt. It's very comfortable and gives a lot of support and I can sleep on my front without my back hurting like it did with my old mattress. I'm very happy with this mattress but if you want medium support it may not be for you 15 February 2014
Rated 5 out of 5 by Amazing This mattress arrived today superb delivery with excellent communication re delivery time slot just brilliant. Love the mattress so comfortable especially as i have a bad back. Would recommend 100% defo a fabulous buy with out hassle thanks Asda and Silentnight and the delivery company very very impressed ************** 23 June 2012
Rated 5 out of 5 by Great Mattress for a great price. I bought this mattress as it was on offer but I would have paid the full price anyway! Extremely comfy and well made, I actually expected far less and was surprised how good it was. The mattress is very deep and the memory foam is thick enough to notice you have it. It took a few days to get used to (I had my old mattress for 8 years so I think ANY mattress would take getting used to) but now I really don't know how I managed without it! I would highly recommend this product as you are getting a great product at a great price. 29 September 2014
Rated 5 out of 5 by bedtime heaven! I got the single version for my son, loved it so much i saved up and bought the double version for my own bed. I have never slept so soundly and comfortably in all my 42yrs of life! I no longer wake up feeling like i've been hit by a bus or feeling deprived of sleep. This mattress is pure luxury and at a very reasonable price! I wish i'd bought these mattresses sooner. 16 March 2014
Rated 4 out of 5 by Great service Great service, Very good product, I would buy from Asda again as they are very good value. 03 July 2014
Rated 4 out of 5 by It's a mattress! As with so many review sites, I've only had this for just over one week so it's far too early to give a true appraisal. It is a comfy and reasonably firm mattress... with an odd smell? I suspect this is some sort of lacquer / protection, but it's rather offputting. However, I believe the smell with slowly disappear as it does not seem quite so obvious today, as yesterday... 23 January 2015
