Top five memory foam mattresses
This mattress is one the firmest boxed beds we’ve seen, earning a five
on our firmness scale of one to ten. It provides good support for everyone,
but is especially supportive if you sleep on your back. It doesn’t restrict
your movement, making it easier to roll over and change sleeping position in
the night, though doing so shouldn’t disturb your partner because it absorbs
impact really well, too. You can try it out for up to 100 nights while still
being eligible for a full refund.
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 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 mid-range 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, and larger 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.
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.
A memory foam mattress to avoid
This mattress combines memory foam with pocket springs — but unfortunately not to good effect. It provides very poor spinal support for people sleeping on their back and to make matters worse, the support for back-sleepers becomes even worse over time, while the mattress also sags dramatically.
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.
