Q & As

Rated 4.3 out of 5 by 8 reviewers.
Rated 5 out of 5 by Great night's sleep! I've had this mattress for about a month now, it's fantastic. A really good night's sleep. It's very firm, but don't worry, it isn't too firm. A really great purchase. 10 February 2015
Rated 4 out of 5 by NOT VERY FIRM Mattress is not as Firm as specified--edges are worryingly soft [slide off the side if I'm sitting to put my socks on, say] but it is thick and bouncy so should last a few years. The delivery chaps were utterly wonderful and did everything, were on time, and worked efficiently. 28 January 2015
Rated 4 out of 5 by Exactly as expected Delighted with this purchase Exactly as described and very good value A lovely firm mattress Delivered as requested and on time 09 December 2014
Rated 5 out of 5 by A firm and comfortable mattress Really pleased with this Silentnight Comfort Miracoil Mattress. It's firm and comfortable and very reasonably priced. It's the second one I've bought over the past 12 months; the recent purchase was for my daughter who also finds it firm and comfortable with good back support. A good choice all round. 30 September 2014
Rated 1 out of 5 by appalling I bought this mattress on the strength of the other reviews . BOG MISTAKE, it is literally like trying to sleep on a mortuary slab, neither my husband nor I can get a wink of sleep on it and its so hard our shoulders and arms go numb. 18 May 2014
Rated 5 out of 5 by really comfortable 1 bought this mattress entirely by reading the recommendations from the on-line reviews. On waking after the first night with chronic back-ache I got a told you so from my husband who doesn't agree with buy large items of furniture on-line. However, I have had the last laugh as the mattress is really comfortable and I have no regrets whatsoever and would recommend buying by taking into account the views of the people who have gone before you, I is of excellent quality yet good value. 22 January 2014
Rated 5 out of 5 by Outstanding value I was in desperate need for a new mattress after months of sleepless nights and finally decided to sort it out. I have mixed ideas about buying a mattress over the internet but thought "i can return it if unsuitable". I wanted a firm mattress and didn't want to pay a ridiculous amount- this mattress is perfect! Its nice and high(i will have to buy flatsheets as my fitted sheets don't quite fit now) and is firm and solid to lie on without being too much so. My mum took the delivery for me and said she was very impressed- called to say they would be 15 mins away, and they were. Took the old mattress away and delivered the new one in a friendly and efficient way. Now looking for single mattress's for my children's rooms. 08 December 2013
Rated 5 out of 5 by At last a really good nights sleep! I was worried about buying another mattress on the internet because it is hard to judge the firmness of a mattress without testing it. I should not have worried -This mattress is described as FIRM and it is exactly that. For the first time in months I have slept on my mattress instead of "inside it". Thank you John Lewis and Silentnight for the instant improvement in my sleep quality. Thank you for the very speedy delivery - my mattress came so quickly I didn't have time to buy my new bedding before it arrived. First class as usual! 12 November 2013
