A memory foam mattress to avoid
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 mattress should keep your spine in a parallel position 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.
