    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.

  • This memory foam mattress gives exceptional support 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. There are a couple of downsides, though.

  • This lightweight mattress has no real major flaws, it offers good support for your spine and is pretty durable, but over time there is a slight change in firmness, it's still acceptable though. At this price, if you want a memory foam mattress, it's worth considering if your budget is tight.

How to buy the best memory foam mattress

Memory foam mattresses, also known as memory mattresses, are topped with a layer of temperature-sensitive viscoelastic material (memory foam). 

Some people swear by memory foam mattresses, but they don't suit everyone. 

Memory foam mattresses are the third most popular type of mattress among Which? members. About 16% of the members we surveyed about their mattress had bought a memory foam one.

If you're tempted by one of these mattresses, you'll need to think about which type you want and how much you're willing to spend. Otherwise you might end up a dud that you'll wish you could forget.

Pros:

  • Memory foam mattresses are good at relieving pressure on painful joints.
  • Those who like memory foam seem to love it – as one owner told us: 'my memory foam mattress is the most comfortable mattress I’ve ever had.
  • Memory foam mattresses generally can't be turned over. But you can turn them around, and some mattresses have handles which make this easier to do. 

Cons: 

  • Can be pricier than sprung mattresses
  • Feel very different to lie on than regular sprung mattresses. This means memory foam mattresses aren’t for everyone.
  • Some of you have said that you find memory foam mattresses too hot.
  • If you want to buy one already, go straight to our memory foam mattress reviews or see our selection of hybrid memory foam and springs mattress reviews.

Do memory foam mattresses mould to your body shape?

Memory foam mattresses mould to your body shape

Memory foam is affected by room temperature, so you might find the memory mattress cold and hard when you first go to bed. 

As it reacts to your body heat, it moulds to your shape - this can make it more difficult for you to move or get out of bed compared to other mattress types.

Memory foam also reduces air circulation around your body, which makes the memory foam mattress feel warmer. Many people find this helpful in winter but you may feel too hot in summer.

If you usually use an electric blanket, it's important to note that many manufacturers say not to use one with memory foam, as it's a potential fire hazard. However, we will point out in our reviews if this is possible. 

But as a memory foam mattress is warmer, you shouldn't miss it. If you do, add a blanket or go up a tog on your duvet. Need a new duvet? Head to our Best duvets to find the ones our members rate as the best.

What is a memory foam-only mattress?

memory foam-only mattress

Some memory foam mattresses are actually sprung mattresses with a layer of memory foam on top, otherwise known as a hybrid mattresses. You''ll find these on sale from all the big bed-in-a-box brands such as Emma, Eve and Simba.

Some, however, have extra layers of memory foam instead of springs. These are often described as pure memory foam, or memory foam-only, mattresses.

They tend to be pricier and softer, but not necessarily better - some pure memory foam mattresses impressed in our tests, while others were poor.

Can you buy a cheap Best Buy memory foam mattress?

Like most mattresses, Memory foam versions can cost as little as a a couple of hundred pounds to more then £2,000, but our independent tests show that you don’t always get what you pay for. 

If you're set on memory foam but can't afford to spend thousands of pounds, we've found several cheaper options worth considering.

In fact, we've found one Best Buy memory foam mattress that costs less than £200 - this is fantastic value for money. We also have two which cost £500 or less, so they're cheaper than the average price of the mattresses we've tested. 

All three are made up from different layers of foam and memory foam - great if you want a slightly softer mattress.

Should I buy a memory foam mattress topper?

If you're not quite sold on a memory foam mattress, but fancy getting a feel for the how the foam moulds to the shape of your body, you may want to consider buying a memory foam mattress topper.

It won't make your mattress any more supportive, but it may make it more comfortable. 59% of mattress topper owners told us that they bought their topper to make their current mattress more comfortable, when we surveyed more than 2,000 Which? Connect panel members in September 2021, and a whopping 85% said it make their mattress more comfortable.

Memory foam 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, front 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.

We perform all mattress tests again once we have simulated eight to ten years of use.

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 - all the things you just can't tell by seeing a mattress in the shops. 

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.
