This simple memory foam mattress is affordable and a great Best Buy option if you usually sleep on your front or your back. It has a 7.5cm foam core and another 10cm layer of viscos foam on top. This top layer of memory foam will envelope your body, while this will help stop the transfer of movement across the bed (great news for your bed fellow) it does make it harder to turn over on.

We’ve not seen many cheaper Best Buys than this, and this reasonably-priced mattress scored highly in our tough tests. It comes rolled up in a bag, rather than a box, but this mattress provides good support for everyone but it’s truly exceptional for people sleeping on their back. It’s also easy to roll over on and it won’t dip in the middle or sag, although it will get slightly softer over time.

Jump straight into bed with this Best Buy, and it’ll give your spine the support you need – especially if you like sleeping on your back. It’s excellent at keeping you in the right position. If you prefer to sleep on your side or your front, it will give you decent support here too. It’s durable and not that heavy, either.

It's rare that we test a poor mattress from this brand, and this one doesn't disappoint. It's supportive for both larger and smaller people when new and it doesn't sag, soften or become less supportive over time. It's also suitable for restless sleepers, as it's very easy to roll over on. Doing so may disturb a light-sleeping partner, however, as it isn't the best at preventing the transfer of movement from one side of the bed to the other.

Which? mattress reviews

Not only are we completely independent and impartial, but every mattress we test is subjected to an extensive series of lab tests, all of which have been designed by mattress experts.

Our body support tests, for example, use special equipment to measure the shape of our test subjects’ spines at 36 different points. When you’re lying on your back, a good mattress should keep your spine in the same shape as when you’re standing, while your spine should be parallel to the mattress when you’re lying on your side.

We also measure the firmness, warmth and breathability of mattresses, as well as dropping weights on them and measuring the bounce to see how stable they are. A stable mattress will be good at preventing movement from transferring from one side of the bed to the other, ideally without making it more difficult for you to roll over and switch sleeping positions during the night.

We also simulate up to 10 years of use by rolling heavy human-sized barrels over each mattress thousands upon thousands of times. We then do our body support tests all over again to see whether it has sagged or softened.
