Finding the perfect mattress is essential to improving your quality of sleep. If you’re feeling uncomfortable in the night, you get too hot to sleep or you find yourself slipping into that annoying dip in the middle of the bed, it’s probably time to invest in a new mattress. But with so many options available, where do you even start?

We’ve put together this handy mattress buying guide, to help you make the right choice and take care of your new mattress, too. Read on!

What type of mattress should I choose?

Choosing a mattress is a very personal thing, and finding your perfect mattress means working out what you need from it. For example, if you’re prone to achy muscles after a night’s sleep, you might want to consider an orthopedic mattress. A memory foam mattress will mould to your body shape to provide support through the night, while an open sprung mattress is lighter and easier to turn.

Scroll through the different options below.

What size mattress do I need?

Choosing the right size mattress is important – once you’ve got a mattress up the stairs and unpacked, you really don’t want to have to send it back because it doesn’t fit on your bed!

The best way to ensure you get a mattress that fits your bedframe is to measure it. Measure inside the frame where the mattress sits, and use the table below to work out what your measurements translate into in terms of mattress sizing.

Most beds in the UK are single, double, king or super king, but depending on where you bought your frame, you may have a European size bed which means you’ll need a different mattress.

We stock both EU and UK standard sized mattresses to help you find the perfect fit.

What firmness mattress should I buy?

Your natural sleeping position can determine what type of mattress you go for. Whether you’re a back, side or front sleeper, different levels of firmness will support your sleeping position and ensure a comfortable night’s sleep without that dreaded crick in your neck when you wake up.

Take a look to see how firm your mattress should be, depending on how you sleep.

Is a firm mattress better for back pain?

The right mattress for you will be both supportive and comfortable, and this is particularly important for those who suffer with back pain. A firm mattress is often recommended if you experience back pain, but the main thing to look for is a mattress that keeps your back supported and relieves pressure points on your joints and spine. This varies a lot depending on your weight and how you sleep, so it’s a good idea to try before you buy – all of our mattresses can be returned for free within 21 days, just make sure you don’t remove the packaging.

The pillow you use will also affect your back alignment, so make sure you have one that’s supportive and not too high. Shop pillows here.

Sleeping positions

Sleep on my back


Back sleepers need to strike a balance between soft and firm when it comes to their mattress, so a medium firmness is the best option to go for. When lying on your back, it’s vital to maintain the alignment of the spine, but if your mattress is too firm it will put pressure on the bottom of your back. For the best night sleep, opt for a Pocket Spring Mattress to evenly distribute your weight from head to toe.


Combination mattresses or memory foam mattresses are well suited to those who sleep on their side so that they can mould to the curves of your body whilst you sleep. A mattress that is too firm will cause discomfort and unnecessary pressure for side sleepers so opt for a memory foam mattress or a mattress that has an inbuilt layer of foam at least.

Sleep on my side
Sleep on my front


The Pocket Spring Mattress is well suited to someone who sleeps on their front. Front sleepers need more support than side sleepers to ensure the spine stays aligned and not too much pressure is inflicted whilst you sleep. Therefore, a firmer mattress is recommended for front sleepers and a Pocket Spring will distribute the pressure perfectly for a sound night’s sleep.

What depth mattress should I buy?

Something that often gets overlooked when shopping for a new mattress is the depth. The average height for a mattress is between 9-12 inches – most people will find this comfortable and mattresses at this depth will fit most bedframes.

Memory foam mattresses can be higher at 12 inches because they’re usually denser to give more back support. pocket spring mattresses have less depth because the springs take up less space. Choosing the depth of your mattress is a personal thing – lots of people love that feeling of sinking into a deep mattress, whereas others like a thinner mattress that feels firmer.

A good way to work out what you like is to measure the depth of your current mattress – if you find it comfortable (but it’s just time for an upgrade), stick with it. If you want something a bit more luxurious, go for a deeper style.

How should you sleep while pregnant?

A comfortable, supportive mattress is essential for everyone, but especially if you’re pregnant. Pregnancy is a very tiring time and you want to ensure your sleeping space is perfect, so you can catch up on that all-important sleep.

Once you’ve reached your second trimester, it’s recommended that you don’t sleep on your back as the weight of your baby can put pressure on main blood vessels and make you feel faint. Switch to side sleeping at this point, and look for a firm mattress that offers more support.

In the third trimester when your baby is heavier, you might find using a pillow between your knees eases discomfort.

How to take care of a new mattress

So you’ve worked out which mattress is right for you, you’ve bought it and it’s been delivered. Now what? Taking care of your mattress after it’s been delivered is really important and will ensure it remains in tip top condition for many years.

First, let your mattress air out for at least four hours after it’s been delivered. This will freshen it up after being packed and stored and remove any lingering manufacturing smells. Make airing your mattress a regular thing from here on, removing your bed linen for a few hours to let air circulate before putting clean sheets on.

Turning your mattress will really help extend its life too – flip it over and turn it round every six months or so to stop dips forming and keep your weight evenly distributed across the whole space.

Finally, consider a mattress protector to really keep your mattress fresh and clean – this is a thin sheet that goes directly on top of your mattress, before your bed linen, and protects it from spills and stains.

Mattress toppers

A mattress topper is an extra layer of cushioning that sits on top of your mattress. As well as providing an extra layer of support and comfort, a mattress topper will give your bed that super luxurious, hotel feel – perfect for crawling into after a long day!

Mattress toppers come in a range of materials, from goose down, cotton and wool to microfibre and fleece. Your perfect style will likely match the kind of duvet you have – natural fibres are great for ultimate cosiness, while synthetic styles work well for allergy sufferers.

Can you wash a mattress topper?

Just like a duvet, how you wash your mattress topper will depend on what it’s made of and what the instructions say. Always check the label before throwing it in the washing machine – down and wool styles may need delicate cycles, and memory foam toppers should be spot treated for stains and not washed in the machine.

Now you’ve got all the info you need, you can go forth and buy a mattress that’s supportive, comfortable and perfect for you. And once you’ve got the mattress, you might want to check out our guides we’ve created such as buying bed linen.
