Q & As

Rated 3.9 out of 5 by 11 reviewers.
Rated 5 out of 5 by Best nights sleep Admittedly I was previously sleeping on a bog standard mattress but this mattress is great. Good value for money and very comfortable, medium to slightly firm in support. Overall I am very happy and would definitely recommend. 01 December 2015
Rated 4 out of 5 by Comfortable for a good night sleep My partner prefers a firm mattress but this medium mattress works well for him. I tend to sleep on my side and this mattress offers sufficient pressure relief and motion isolation when one of us toss and turns. Delivery was prompt. 29 September 2015
Rated 1 out of 5 by Cheap and didn't last more than 2 years. Lots of people write reviews when the product is new - which in some ways defeats the purpose. Durability is the true test of quality. This mattress was appalling and within 3 months was saggy and uncomfortable and the minimal memory foam just that - a distant memory. 03 July 2015
Rated 5 out of 5 by Amazing Value This is the second mattress I've bought from John Lewis..... I shopped around as I didn't want to spend alot on a mattress for the spare bedroom... but at the same time didn't want a guest to think they were sleeping on the floor. This mattress is fantastic value and as good as anything your buy elsewhere for twice the money. 21 April 2015
Rated 5 out of 5 by The rhyming rater The mattress has springs They are my thing. Springy for days, I woke up in a haze.. I hope my missus stays. 26 August 2014
Rated 5 out of 5 by Not basic at all! We purchased this mattress for our spare bedroom. Even though it's 'basics', it's incredibly comfortable and you'd think you'd purchased a much more expensive product. Utter bargain! 26 August 2014
Rated 3 out of 5 by bigger than stated We bought this mattress to replace our current John lewis mattress.. It is a lot wider than our current one and larger than measurements stated. We r now having to return it an wait in hope that the double is going to fit our frame .. 20 June 2014
Rated 5 out of 5 by Fantastic value !! Really pleased with this mattress - it's so comfortable and wish I had bought it years ago 03 June 2014
