Top five memory foam mattresses
In general, we’d advise you to be wary of any mattress that you can’t try until you buy. But there’s a growing number of online-only brands that offer extended trial periods, during which you can send it back for a full refund if you don’t find it comfortable. This mattress is one of these, and we were so impressed with it we made it a Best Buy. It’s supportive, no matter what your body shape or sleeping position, not to mention stable, breathable and easy to turn over on. And it’s very durable, so you’ll enjoy these benefits for years to come.
You'll get exceptional support from this mattress if you tend to sleep on your back, although the support for side-sleepers is good, too. In addition to being very long-lasting, this mattress is also well-suited to light sleepers because it's really good at preventing movement from transferring from one side of the bed to the other. That stability has a slight downside, though - this mattress restricts your movement a bit, so it requires a little more effort to turn over on this mattress.
This bargain memory foam mattress is perfect for side-sleepers, as it will excel at keeping your spine almost parallel to the bed for years to come without sagging or softening. The memory foam absorbs your partner’s movement exceptionally well, without the common downsides of feeling very warm to lie on and not being breathable. The only two things to consider are that back-sleepers can get better support from other mattresses, and you can only make use of the 100-night sleep trial if you use a mattress protector.
This mattress, which we tested as recently as December 2017, is a great bet for the new year if you’re looking for a combination of memory foam and pocket springs. It’s easy to roll over on and yet provides high-quality and long-lasting support without sagging or softening. Light sleepers may want to look elsewhere, though, as it’s not as good at blocking your partner’s movement from transferring to your side of the bed.
This reasonably priced memory foam mattress is a great all rounder. Whatever your size or sleeping position, this mattress does a good job of supporting your spine, but it’s exceptionally supportive for smaller people who sleep on their backs. It’s worth considering if you or your partner is a light sleeper, because it’s really good at absorbing bounces. The only things to bear in mind are that this mattress restricts your movement a little more than some we’ve seen, and, although the quality of support doesn’t deteriorate, the mattress will get slightly softer with time.
A memory foam mattress to avoid
This mattress is from is a well known and respected memory foam brand, but you should avoid it if you spot it in the shops – even if you think it’s comfortable when you lie on it. There are some issues with body support and, even more importantly, we have real concerns that this expensive mattress won’t stand the test of time. A large tear developed in the centre of the mattress during our durability tests, rendering it unusable.
Which? mattress reviews
All our mattress reviews are based on extremely rigorous and independent testing, so you can rest assured that our results will help you find the very best mattress for you.
Whether you're big or small, and sleep on your back or your side, we test every mattress to see how well it will support your spine. If you sleep on your back, a great mattress will keep your spine in the same shape as when standing; if you sleep on your side, your spine should keep your spine parallel to the mattress. That's what we look for when we test body support.
To make sure the support doesn't deteriorate with time, we perform all the tests again once we have simulated eight to ten years of use in our durability tests.
It's not just about support and durability, though. We also measure how breathable a mattress is, how easy it is to turn over on, and how stable it is. So, whether you're a sweaty sleeper, or a light sleeper who's sick of being disturbed by their partner, we've tested something that will suit you.
