Q & As

Rated 4.9 out of 5 by 23 reviewers.
Rated 5 out of 5 by Wonderful matress The silent night mirapockect 1200 memory mattress is an excellent choice if you want something with medium softness but not too much. I look forward to my night sleep. Since we had it my husband has stopped having problems with his back as our previous matress was hard. I also find the bed warmer than other beds and I love this particularly on a very cold night. Is quite a thick matress but so light at same time. I love it and is worth investing the money. 08 December 2015
Rated 5 out of 5 by Well rested Excellent mattress, good support without being too firm. Memory foam top very responsive to changing position and you don't have to turn the mattress over every 2 weeks, just turn 180 deg, bonus. 06 December 2015
Rated 5 out of 5 by Comfort on a whole new level! It's a big purchase, so lot's of research was definitely the key. And finally ( when you've narrowed it down) the recommended testing time of 30 mins is correct ... don't just hop on and off like most people! This mattress was super supportive and yet very comfortable straight away on the shop floor, but when the new one arrived it seemed much firmer. Even with the firmer feel, it still is incredibly comfortable. My partner took a full week to get used to it and is now very happy with it. So, the advice on the leaflet about giving it some time, is definitely helpful. The stability is also excellent, so if one partner gets up in the night they don't wake the other. We're really thrilled with our choice! 02 December 2015
Rated 3 out of 5 by Too firm On trying this mattress in the shop, it felt really comfortable. I told the sales assistant that my previous mattress was a Tempur and she recommended this one, as it contains memory foam. However I found my new mattress gave me terrible hip and back pain, so I've ended up buying a memory foam topper as well. Maybe it takes a while to break it in, so I've been walking on it, in between sheet changes! 01 December 2015
Rated 5 out of 5 by Wonderfully comfortable Blissful night's sleep on this mattress so glad I bought it. 25 November 2015
Rated 5 out of 5 by Very comfortable Bought based upon reviews as unable to get to the store. Very pleased. Delivery team first class 11 November 2015
Rated 5 out of 5 by Brilliant Mattress Brilliant mattress fantastic 1 of the most comfortable mattress I've ever slept on fantastic support for your back recommend medium to firm it's amazing and soft at the same time well worth the money I paid for it. I've had cheaper memory foam mattress in the past and nothing compares to this 1. 10 November 2015
Rated 5 out of 5 by A good night's sleep ! Too often we say 'I should have replaced the mattress earlier', and yes I'm another one. Tried several in my local store and this one definitely beckoned! It's 300 less springs than previous mattress, but with memory foam. Sleeping well, waking without aches, cosy support, what more could be asked.. I've heard memory foam may make a hotter bed and this may be so, but we're heading into winter and certainly no discomfort presently. 15 October 2015
