What mattress firmness do I need?

While many may opt for a super soft mattress for super cosiness and comfort, everyone has different preferences when it comes to the firmness of their mattress. The rule of thumb is that heavier sleepers should opt for firmer mattresses, as a sleeper’s weight determines how deeply they’ll sink into a mattress.

However, many factors can determine what type of firmness you should choose with your mattress. Correct support during sleep depends not only on your weight, but your height, build, and preferred sleeping position. It’s the same for comfort, some may prefer a firmer mattress, and others may prefer being cocooned and sunk into their bed.

To help you find the type of mattress that’ll support your preferred style of sleeping, explore the different mattress firmness options, below.

What are the different types of mattresses?

From different types of foams to various spring designs, mattresses types vary to accommodate many different sleepers. Let’s find out which mattress type is just right for you and how to pick out a mattress.

  • Best For: back & front sleepers, couples.

Open coil

If you suffer from back or joint pain and are looking for a mattress to help relieve it, you might want to consider an orthopaedic mattress. These mattresses are usually on the firmer side, and are designed specifically to provide superior support to the joints, helping ease pressure and offer relief to those with back pain and other types of chronic joint pain.

With so many options to choose from, it can be a bit overwhelming choosing a the right mattress. Don’t worry - we’re here to help you find your sleep thing! Just answer a few questions about how you sleep, and we’ll share the perfect mattresses for your dream night’s slumber…

What mattress do I need?

When you’re looking for your next mattress, your personal sleeping issues can be some of the most important factors in making a decision. These problems vary from sleeper to sleeper, and your old mattress could be causing you more issues than you realise.

For example, some common sleeping and mattress issues include back pain, joint pain, allergies, running too hot at night, and being affected by your sleeping partner’s sleep behaviour.

The good news is, that no matter your sleeping issues, there’s likely a mattress that can help alleviate them.


What is the best mattress for back pain?

Generally speaking, firm mattresses are best suited for supporting sleepers with back pains. Opting for a medium-firm mattress is a good choice for those seeking comfort as well as relief, as these mattresses support joints and ensure your spine is kept aligned.

Similarly, memory foam and latex mattresses also help with back pain. Thanks to the foams’ special properties, they contour to a sleeper’s body, which cradles pressure points. With this in mind, our top picks are our Silk Ortho Mattress and our Latex Pocket Sensation Mattress.


What is the best mattress for allergies?

If you suffer from hay fever, asthma, or any other sleep-disturbing allergy, then you’ll need a hypoallergenic mattress. We recommend opting for a Silk Memory Supreme Mattress or, for a softer, foam-only option, take a look at Just Relax by Silentnight.


What is the coolest mattress to stop me overheating?

For people who always get too hot at night, choosing the coolest mattress could hold the key to better sleep. Your first option is to look for a mattress with better airflow, such as a pocket sprung mattress, which doesn’t trap as much heat under your body.

You can also opt for a mattress with a cooling gel or system. Our Eco Comfort Breathe Pocket Mattress is a perfect example of this, thanks to its ‘microclimate system’ and special ‘eco breathe fibres’.


What is the best mattress for couples?

Sometimes, the biggest threat to your sleeping pattern is the partner snoozing next to you – but a new mattress can help!

In this respect, we recommend looking at a pocket sprung mattress; the bigger the better. For example, a firm king size mattress would be your best bet. The pocket springs are individually nested, which means that the entire bed doesn’t shake when your partner rolls over.

Those looking to add more comfort to their night should consider a pocket spring mattress with a pillow top, such as our Rylee Mattress. Or, for a more secure choice that features special foams, there are options like our Silentnight Geltex Mattress.

How to look after your new mattress

Once you’ve picked out your perfect mattress and brought it home, you’ll want to keep it looking and feeling its best for as long as possible. Thankfully, there are some simple ways to do just that.

flipping mattress

Flip or rotate your mattress

Our first tip is a simple one: flip or rotate your mattress every six months. This helps to distribute the impact of sleepers’ bodies over time. If weight isn’t distributed properly, this can lead to the mattress sagging.

Whether a mattress should be flipped or rotated depends on the mattress structure. Most mattresses should be flipped over to minimise this damage. However, some special types of mattresses, such as pillow tops, need to be rotated instead.

If you’re unsure whether you should flip, rotate, or both flip and rotate your mattress, check the care label on it.


Regularly clean and air out your mattress

Like any other regularly used piece of furniture in the home, your mattress needs a regular clean to keep it nice and fresh.

First, remove any accumulated dust from the mattress with a soft brush. Then, give the surface a once over with a cloth dipped in warm, soapy water. Leave to dry before dressing the bed again.

There are other smaller steps you can take to ensure your mattress remains clean for longer. You can air out your mattress every day, simply by pulling back your covers for a couple of hours. You can also regularly wash your linens and bedsheets once every one to two weeks, which helps to keep the mattress fresh.

Mattress FAQs

Once you’ve established the mattress size, type and firmness that’s right for you, there are still plenty of ranges and products to choose from - so how do you decide how to pick a mattress? When it comes to choosing a mattress that meets your preferences, you should always buy the best you can afford, because higher quality mattresses will provide longer lasting support and offer a better night’s sleep. Purchasing a mattress from a reputable retailer or brand is also a good bet, as you’ll know it’s been thoroughly tested for long-lasting quality, and made from materials that are safe to have in your home.

When shopping for a pocket sprung or coil sprung mattress, generally speaking, the higher the spring count, the more support it will offer. Mattresses with more springs use more materials, and therefore generally cost more, but they will offer more targeted support and isolate movement more effectively - particularly helpful if you find your partner disturbs your sleep in the night. Many ranges include similar mattresses with different spring counts, so you can choose the sprung mattress that suits your budget.

Everyone’s comfort needs are different, and so it’s unsurprising that it’s difficult to generalise what the comfiest mattress may be for you. While the most popular mattresses are medium and medium firm, some people prefer the sink-in feel of a soft mattress, while others prefer the support that comes with a firm orthopaedic mattress. Some people love the way a memory foam mattress moulds to their body shape, while others prefer the cooling air circulation you experience on a pocket sprung mattress.
