The ultimate guide to purchasing a memory foam mattress, with helpful tips from our product experts.
Memory foam mattresses are a popular choice and are suitable for all types of sleepers, whether you lay on your side, back, or front. If you place value in cushioned comfort with a velvety smooth feel, memory foam mattresses could be for you.
A memory foam mattress has a layer of memory foam with either springs or support foam beneath, depending on type.
Originally designed for NASA, memory foam, as its name suggests, has a 'memory'. This means that you can apply pressure to the foam, and your body heat will soften the material so it can to the shape of your body that is forming the pressure.
Once the pressure is removed, the foam remembers its original shape and bounces back slowly. Eventually, the foam also ‘remembers’ your body shape too, giving you the optimum sleeping position as soon as you lay down.
This ability to mould and remould without losing that essential level of support makes memory foam ideal for mattresses. The feeling of being cradled rather than laying on top of a rigid surface means that you can find a comfortable position more quickly, ensuring a more restful night's sleep.
Here are seven key benefits of a memory foam mattress:
A defining characteristic of this soft material is that it contours to your body and reduces pressure on your spine. This is ideal for those who sleep in many different sleeping positions as it provides excellent pressure point relief for your joints and limbs. It properly aligns the neck, spine, and hips.
Ever slept on a surface that is too firm? Having your full body weight on pressure points all night as you sleep can make you feel sore in the morning. This mattress reduces pressure spots across your body by evenly distributing body weight, helping to correct a poor sleeping posture. Encouraging a healthy sleeping position also helps to reduce chronic back and neck pain.
Memory foam supports the curve of your neck, easing your breathing by keeping your airways clear and open. This contributes to better sleep quality and is appealing to people with sleep apnea.
Memory foam mattresses are made from materials that make them hypoallergenic and dust mite-resistant. This is ideal for people who have allergies, asthma, or respiratory problems.
Memory foam is silent – coils in a traditional mattress can start to squeak and creak over time. This issue doesn’t happen with memory foam, which can help you get great sleep.
The body contouring mattress stops movement from being transferred, which means you’ll be undisturbed when the person you’re sharing a bed with moves or rolls over. This is perfect if you’re a light sleeper or your partner is restless.
Memory foam mattresses are one-sided, with the foam layer only on the top side. This means you shouldn’t flip them but rotate them instead.
Memory foam isn’t a one size fits all sleeping solution. There are actually many different types of foam mattresses available, each with its own characteristics and benefits.
Latex mattresses are similar to memory foam but are made from an entirely natural material harvested from the rubber tree. They are renowned for their luxurious natural filling and superior, denser posture support and have less 'sink-in' than traditional memory foam, while offering trademark plush comfort.
Latex is also super breathable and doesn't retain as much heat as traditional memory foam. You can read more about this natural alternative to memory foam in our Latex Mattress Buying Guide.
A form of cooling memory foam, these gel mattresses are perfect for those who tend to overheat at night, regulating temperature and airflow while retaining that classic memory foam feel. Choose a gel memory foam mattress for a cooler night’s sleep.
Cooling gel is also great for memory foam pillows, especially if you love the 'cool side of the pillow' feeling.

This pioneering sleeping solution blends all the benefits of pocket-sprung mattresses with the supple comfort of memory foam.
This is a hybrid mattress that is breathable and supportive without sacrificing any softness. Pocket foam mattresses have sprung foundations topped with a generous layer of memory foam – the best of both worlds.
Our Hybrid Mattress Buying Guide will help you decide if this is the mattress type for you.
There are several different features of memory foam mattresses to consider when choosing the perfect sleep surface for you.
There are three main types of memory foam mattresses:
It is also possible to get hybrid mattresses that offer memory foam comfort layers along with more traditional structures, such as pocket springs. These are a great choice if you’re looking for the best of both worlds and additional support.
The density of memory foam is how heavy it is compared to how big it is. How dense the memory foam is impacts mattress longevity, durability, and the amount of support it gives you. The denser a mattress is, the more longevity it has.
Memory foam densities range between 3 to 7 pounds, with the higher end being more premium and usually lasting longer. Knowing which density not only suits your sleep style but also your budget will help narrow down your options. Find out more information with our guide on memory foam mattress density.
Memory foam mattresses have several layers and vary between brands. There are two layers that are most important.
Memory mattresses are typically in the range of 8 to 14 inches. A standard mattress thickness is around 10-12 inches which is enough support for the average adult sleeper, however, you can get thicker if you’d like even more support.
How firm you want your mattress totally depends on personal preference – there is no right or wrong answer. We offer memory foam in a range of firmnesses:
Take a look at our guide on preparing and caring for your memory foam mattress for information on how to make it firmer or softer as your needs change.
Due to the popularity of memory foam, there is an incredibly wide range available at different price points. We stock memory foam mattresses to suit every budget, from as little as £140.
However, the level of comfort and support you get from your memory foam mattress is going to increase the more you spend on it - higher quality materials are more expensive to produce, but we always ensure you get the very best price possible.
Choosing the right memory foam mattress size will guarantee you have enough space to truly relax, especially if you’re sharing the bed with your partner and don’t want to be squished next to each other.

The right bed frame is incredibly important for a proper night's rest. Make sure you pair the correct frame with your mattress otherwise this can void the brand’s warranty.
The best type of bed frame for a memory mattress is a platform bed or a standard bed frame. This choice will provide proper support and will enhance the features of the viscoelastic foam, letting air circulate properly.
We've also created a guide to the best bed frames for a memory foam mattress, so take a look at that for more help in choosing your sleep set-up.
A memory foam mattress is made of several supportive and comfortable layers of polyurethane, a material which contours around the shape of your body and relieves pressure points. This makes it one of the best materials for those with back pain, or people who are looking to correct their posture.
The body contouring characteristics of this viscoelastic foam help to support the natural curves in the spine, which help align it and reduce pressure spots on other parts of the body like shoulders, hips, and knees. If you’ve ever slept on an overly firm mattress, you’ll likely have felt sore the next day where these areas have dug into the material.
We also have a range of memory foam mattresses with specific orthopaedic support features.
Memory foam mattresses are suitable for a range of people from those who want pain relief, those who sleep on their side or regularly toss and turn, and those who simply love a soft, comfortable sleep.
However, we’re dedicated to ensuring you get the very best mattress for you and your unique needs. We’ve compared memory foam to other types of mattresses so you can be sure to get the right one for you.
Orthopaedic mattresses are more specialist than memory foam – they are more suitable for people who experience pain when they sleep, those in active recovery from injury, and older people. Doctors can recommend them if you have back pain or other similar medical conditions.
An orthopaedic memory foam mattress features a layer of memory foam for comfort as well as orthopaedic support. This means it is slightly firmer than a typical memory foam option, helping maintain a correct posture while in bed and aligning your spine.
Rather than foam, a pocket sprung mattress is made of hundreds or even thousands of coils that are encased individually. Each individual pocket spring moves independently to adapt quickly to different weights and sleep positions.
A higher spring count generally provides better support and a firmer feel. Pocket-sprung mattresses are ideal if you wish to lay ‘on top’ of your bed, rather than ‘sink in’ like you would with memory foam.
A hybrid mattress generally involves a layer of pocket springs with a pillow top made up of memory foam or a similarly comorting foam. These are arguably the best of both worlds - you get the intense support and firmness from the springs, with the sink-in feeling of the memory foam.
We offer unique combinations of hybrid mattresses, so you’ll be able to find one that perfectly suits your needs.
A gel foam mattress is similar to memory foam, with cooling gel pods added to the foam layer. Gel foam also bouncier and moulds back to its original shape faster than regular memory foam.
The main difference between memory foam and gel memory foam is heat retention. This type of mattress draws warmth away from your body which keeps you cool while you sleep.
