For the highest standards of quality and safety
Settle in for quality sleep atop the Silentnight Sleep Right™ Memory 1400 Mirapocket® Mattress. Featuring pressure relieving Memory foam with a core of zoned support.
Pocketed support
A core of Silentnight's Mirapocket® springs offer incredible zoned support. This enhances your rest by targeting key areas of the spine, helping to improve sleep posture. Making it easier to sleep comfortably and deeply by providing superior support.
Isolated into individual fabric pockets, allowing them to move separately. These springs also minimise motion transfer and feelings of 'roll-together'. Helping you to remain undisturbed throughout the night.
Soothing comfort
The Memory foam comfort layer responds and adapts to the contours of your body. Creating a cradled feel to enhance the comfort of your rest. Helping to alleviate pressure spots, easing aches as you rest. Allowing you to achieve a more fulfilling slumber.
Cosy feel
A layer of polyester fibres is densely packed, helping to create a layer of firmer comfort. This prevents you from sinking in too deep and losing support throughout the night.
Sturdy design
Designed with your comfort and peace in mind, this mattress features a rod edge border. This places a durable rod across the perimeter of the spring unit for a firmer edge. So you can stretch out without a ‘roll-off’ feel.
Proven perfection
In-house testing at Silentnight includes mapping analysis that has proven that the Memory foam disperses pressure. Working with experts in movement analysis found an improvement in lower spine support when compared to standard sprung mattresses.
Assured quality
As one of the first B-Corp certified™ sleep brands, Silentnight have proven why they are the UK’s most trusted name in sleep. Their commitment to quality and environmentally responsible practices ensures a better night’s rest and a brighter future for you.
Complete with a 5 Year Guarantee to ensure you get the quality product you deserve.

I bought one bed that was soft for me it was supposed to be firm but it turned out to be not so the exchange it for this one I’m reviewing this was a cheaper bed supposably firm, I lost 100 and odd pounds because it didn’t refund the full amount this company, should not treat their customers like this. Stay away from mattress online you will not be happy I am not a happy customer at all in fact I’ve spent over £650 but now I’m going to have to buy another bed… So that says it all

Hi David I am sorry you are not finding your mattress comfortable - we appreciate the feedback. I can see that you have contacted our Customer Service team regarding exchanging your mattress. Unfortunately, we only offer one Comfort Trial per order so would not be able to exchange the mattress again. Kind regards Charlie
Fantastic mattress I love the silent night range. I can not stress how comfy this mattress is it's a very firm mattress which I feel will be long-lasting. This replaced my old mattress which I bought only 4 months ago and I'm glad I purchased the new one been using this for a week now and I'm sleeping right through the night and waking fresh and relaxed.Would happily recommend this mattress and the silent night range.

I ordered a size Super King. It's a heavy 42kg and must be carried with 2 people or 3 upstairs. Beautiful design and good firm mattress. Good support for Your back and nice night.

I was given a discount to buy this product in return for an honest review. As a normal matress I would have scored it 4/5. However because this was a memory cool matress I have to rate it for its feature. Me or my partner didnt feel any benefit of the cool or breathable feature. The firmness of the matress was said to be meduim-firm I would definitely say it more firm than medium. However we have found it to be comfortable enough for a good night's sleep. You don't sink into the pockets but they are supportive. We have added a mattress protector for a little extra comfort. My partner has found he moves around less in the night also. Would I have purchased this if it wasn't discounted? Probably not. Only tested for a week I will update if there's any changes.

Mattress Review.Absolutely Delighted with My Silentnight Memory Pocket 1400 Mattress!I recently purchased the Silentnight Memory Pocket 1400 single mattress and I couldn't be happier with my choice. From the very first night I noticed a huge improvement in my sleep quality. The memory foam layer adds a lovely plush feel while the pocket springs provide excellent support adapting to my body and helping to reduce any pressure points.What I also love about this mattress is how it strikes the perfect balance between comfort and firmness. It's supportive without being too hard and it has really helped me wake up feeling refreshed and free of aches.The build quality is also superb—it feels durable and well-made giving me confidence it'll last for years to come. Plus being a Silentnight mattress I trust the brand's reputation for quality and comfort.Overall I highly recommend the Silentnight Memory Pocket 1400 if you're looking for a comfortable supportive mattress that doesn't compromise on quality. My only regret is not buying it sooner!

Best decision I've made in a while to get this mattress. Had the best night's sleep I've had in a while. It is nice and thick and well made with handles on the side to help when moving it. The only negative is that it's suppose to be a cooling mattress and I didn't really feel like it was cool other than that I love it.
