When it comes to price and test score, there’s little to choose this mattress and another on this list. But while both mattresses are excellent, there are some subtle differences you should consider before you buy one of these bed-in-a-box brands. If you tend to sweat during the night, you’ll be interested to know that this one is slightly more breathable. However, it’s also slightly softer, which won’t suit everyone. Both mattresses are generally supportive, but this one is fractionally better for side sleepers, while its rival has the edge if you sleep on your back.

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.

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.

If you’re looking for a cheap memory foam mattress, you’ll want to add this one to your shortlist – especially if you sleep on your side or need a new mattress in a hurry. While it’s supportive for everyone, it’s particularly well suited to side sleepers. It comes vacuum packed, so you can try it out in store and take it home the same day. If you like the feel of it in the shop, you can be confident that you still will in years to come, because it doesn’t sag or get softer with time.

This mattress has been around a few years now, but it’s still one of the best if you’re looking for a combination of memory foam and pocket springs. Unless you’re taller and heavier than average and sleep on your back, this mattress will provide your spine with good support for years to come. Unlike some memory foam mattresses, this one is very easy to turn over on. Yet it’s also really stable, so you shouldn’t disturb your partner when you do. However, you may want to look elsewhere if you tend to get too hot during the night, as this mattress feels warmer to lie on than average.

This mattress comes from 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.
