How to Choose Your Brand New King Size Mattress?
Now that you’re familiar with the different types of king size mattresses, it’s time to work out exactly which mattress will be the best option for you. It’s important to give this decision plenty of consideration. The right mattress can provide you with many years of comfortable and healthy sleep, and can even improve back or joint pain if you suffer from it.
That said, the wrong mattress can also worsen or even cause night time aches and pains, and can seriously disturb your slumber. As you can see, choosing the most comfortable king size mattress is a decision not to be taken lightly.
What is the best king size mattress on the market? The truth is, the most comfortable mattress is the one that suits you best. So, read on for our expert advice to take the mystery out of buying a king size bed.
Consider your sleeping position
Believe it or not, the pose in which you catch forty winks makes a difference when it comes to selecting the right mattress for you. Why does sleeping position matter? Well, different positions put pressure on different parts of your body. So, what suits a front sleeper is not necessarily right for someone who sleeps on their back.
The most common sleeping position is on your side. This position is generally good for the health of your back. However, it can put pressure on your hip and shoulder joints.
So, you’ll want to choose a mattress that allows your body to sink in comfortably. Memory, gel or latex foam mattresses are ideal as they conform to your body, but spring mattresses can also be suitable. As long as the bed is soft to medium, this should allow your body to sink in adequately.
Back sleeping requires a firmer mattress to support your spine into a healthy alignment. Any medium-firm to firm mattress can be suitable, however, latex provides an especially good level of firmness. Stomach sleepers are already in a position that is, unfortunately, not very healthy for the spine or joints. If you sleep on your stomach, you’ll need a firm to very firm mattress to give you the support you need.
Do you and your partner sleep in different positions? This can be a challenging conundrum if one person sleeps in a very different way to the other. In this situation, it’s often best to opt for a ‘universal comfort’ mattress. These mattresses are just the right firmness to suit the vast majority of sleepers.
Also, you may be able to find a mattress model that allows you to customize it by selecting a different firmness for each side of the bed. However, bear in mind that these are likely to cost more.
Work out which firmness you need
As we mentioned above, which firmness you need depends largely on your sleeping position. Back and front sleepers require firmer mattresses, while side sleepers will need a soft to medium mattress to reduce pressure on their shoulders and hips.
Another factor to bear in mind is whether you suffer from back pain. You may have been told that back pain sufferers need an extremely firm mattress, often referred to as an orthopedic mattress.
However, this isn’t usually necessary. A medium-firm king size mattress to firm mattress should give you the support you need to encourage your spine into a healthy alignment and reduce pain.
If you and your partner have two differing needs in terms of firmness, you have two options available. You could either buy a universal comfort mattress, designed to feel comfortable for most people, or choose a mattress where you can customize each side to each partner’s personal needs.
For most people, a new mattress represents a major investment. Even if you buy one of the best affordable king size mattress options, it stands to reason that you’ll want to get as much use out of it as possible before you need to replace it. So, finding a mattress with longevity is an important consideration.
So, how do you choose a durable mattress? In general, some types of mattress are more durable than others. As a rule, spring mattresses tend to sag earlier than foam mattresses.
However, you can prolong the life of a spring mattress by flipping and rotating it at regular intervals so one area of the mattress doesn’t suffer excessive wear.
Nowadays, thanks to the internet, it’s pretty easy to check out expert and user reviews to find out if a mattress is durable. This is definitely something to check out before you make a purchase.
Some types of mattress are generally more breathable than others. This is an important factor to look out for as breathable mattresses are better at maintaining a comfortable temperature. That’s because heat can escape from the bedding during the night.
Spring mattresses are a good bet in terms of breathability because they have a lot of air spaces. On the other hand, traditional memory foam tends to sleep hot. That being said, many manufacturers are being smart about using methods to cool down foam mattresses such as incorporating air channels.
So, it is possible to buy a king size bed with memory foam mattress and still stay cool at night. Be sure to check out whether a particular mattress sleeps hot before you commit to buying.
Unfortunately, many of the foams used in mattresses are made using potentially dangerous chemicals. These can release gases into the air around you as you sleep, and can damage your health. This is of particular concern for young children or people with existing respiratory problems. However, nobody wants to be inhaling anything that could make them sick.
So, how can you avoid these nasties in your bedding? The answer is to look for a mattress that has been certified to state that it is made without the use of toxic chemicals. Two key certifications are the Certi-Pur or GREENGUARD certifications. These are independent bodies that inspect mattresses rigorously to make sure they conform to strict safety standards in terms of toxin emissions. You could also consider purchasing an organic mattress, which must be made without chemicals that could harm people or the environment.
Bed frame compatibility
If this is your first king size mattress, then you’ll be buying a new bed frame in any event. However, if you already own a king size bed and are simply replacing your mattress, you’ll need to make sure that the mattress you’re considering is compatible with your existing frame.
It’s also worth checking out if you will need a box spring in addition. It’s especially important to check out mattress compatibility if you have an adjustable bed frame, as many mattresses can’t be used with these types of bed.
Depending on the type of bed frame you plan to use, you may also want to check that the mattress you’re buying has a non-slip underlayer. That’s because, if the surface of your frame is very smooth, your mattress could shift position during the night or while you’re climbing in and out of bed.
Whenever you’re buying a high-value item like a mattress, it’s important to check that it comes with a suitable warranty. This should cover any manufacturing faults that come to light within a specified period of time. You should find out whether the manufacturer will repair or replace the mattress in the event of such a fault occurring, and who would bear the cost of returning the mattress.
The industry standard warranty length is around 10 years, which should cover the expected life of the mattress. However, many manufacturers are offering more generous warranty lengths, with some even offering ‘forever’ warranties that last indefinitely. It’s a good idea to check the length of the warranty to check that you’re happy with it.
Although you might not have heard of them before, sleep trials are big news if you’re buying a mattress online. So, what’s a sleep trial? When you purchase a mattress, many companies allow you to return the mattress within a specified period if you’re not satisfied with it for any reason and receive a refund.
This is particularly important if you have purchased your mattress over the internet without trying it out first, as it’s impossible to know for certain whether you will enjoy sleeping on your new bed. As a bare minimum, we recommend that you look for a mattress offering at least a 30-night trial so that you can be sure you’re happy.
It’s worth checking out whether you or the mattress company will bear the cost of returning the mattress in the event that you’re dissatisfied, as shipping a large item like a mattress can be extremely expensive. You may also want to know what the manufacturer intends to do with any returned mattresses. Fortunately, most companies donate any returns to good causes.
Some mattresses have extra features to recommend them that make them unique. For example, some mattresses have special ‘zoned’ support areas to support the lumbar area. This can be helpful for those with back pain. Similarly, some mattresses are infused with substances such as charcoal or even green tea to make them more breathable, durable or hygienic. These features can be a great bonus and are more than worth your while finding out about.
Some mattresses even come with great freebies such as free memory foam pillows. Whilst this probably won’t be a deciding factor, it can be a nice bonus.

Why choose a king size bed?
King-sized beds have boomed in popularity in recent years. Not long ago, almost all couples slept on a standard double and king size beds were considered a luxury. So, why the sudden rise in sales? The main reason for choosing a king-size is pretty obvious: you get more space to stretch out and sleep comfortably. For many couples, this extra space is a real godsend. There are several reasons why plumping for a king-size may be a good option for you:
1. The extra space
A king-sized mattress comes with a generous 76 inches in the width department. To give that figure some perspective, that’s a whole 16 inches wider than a queen mattress. Therefore, when you sleep in a king-size as a couple, that gives each partner a whopping 37 inches of bed width to call their own. Not only does that mean you can stretch out, but you’ll also be far less likely to be disturbed by your partner tossing and turning in the night. The long and short of it is, when you share with a partner, a bigger bed is usually more comfortable.
2. A touch of luxury
Many king size mattresses are made to luxurious specifications, and if you pick a thicker model you can end up with something akin to what you would expect in a 5-star hotel room.
3. Everything in proportion
If you have a large bedroom, a standard double or even a queen mattress can look oddly out of proportion in comparison to the dimensions of your bedroom. For this reason, bigger spaces often look much better with a larger bed to match. You may also feel that a king-size mattress looks in better proportion to your existing bedroom furniture than a smaller model.
4. Maximum range of options
Almost all brands and models of mattresses are available in a king size. Therefore, if this is the size mattress that you decide to go for, you can be pretty sure that you will have just about every option on the market available to you.
Disadvantages of a king size
For many people, a king-size mattress is the best option. However, there are a few drawbacks to king size mattress ownership of which you should be aware. For some people, king size is not necessarily the best way to go.
First of all, if you only have a small bedroom, then king size may not be the best direction to go in. A bed that big can really dominate a small sleeping space and can make your existing furniture look out of proportion. At worst, it can actually take up all of your existing floor space, leaving you squeezing between furniture. Of course, this is not a practical solution.
Secondly, bear in mind that changing the sheets on a king size bed can be more of a hassle than on a smaller mattress. If you don’t have someone around to help out, you may decide this is too much hard work. It can also be a real pain trying to flip a king-size mattress, and we would never recommend attempting this alone. This also applies if you plan to move your mattress from one place to another at any point.
Finally, shoppers on an extremely small budget may find that a decent king size mattress is out of their price range. After all, it stands to reason that a larger mattress will be more costly than a smaller size of the same model. So, you may decide that getting a smaller version of a higher-quality mattress is a better use of your money.
How much is a good king size mattress? That’s a tough question to answer, as there is a wide range available and some can cost thousands. However, in our review section, you’ll be able to find the best king size mattress under $1000.
King vs California King
One area where many people become confused is the difference between a king and a California King size mattress. Many people assume that a California King size mattress is simply bigger in every respect. However, this is untrue and a myth that is worth dispelling.
A king size mattress measures a whopping 75 inches in width and is 80 inches long. If it’s width you’re looking for in a mattress, then this is the best option to go for. That’s because it’s actually wider than a California King. So, it’s the best choice for couples who want to stretch out as much as possible without disturbing their bed mate.
On the other hand, the California King is narrower at 72 inches wide. However, it is significantly longer at 84 inches. Generally, these mattress types are a very good choice for people who are very tall and need the extra legroom. Bear in mind, however, that you probably won’t be as spoilt for choice when you’re shopping for a California king, as not all models come in this size.
Types of King Size Mattresses
Unless you’re completely new to the mattress shopping scene, chances are you’ve noticed that there’s a vast array of different types and models on offer. So, which is best? What is the best king size mattress? You’ll hear some people swearing by one particular type, whereas others will vehemently disagree. The truth is, all the types have pros and cons, and you’ll want to make a decision based on your own personal sleep needs. What suits one person may not suit another.
To help you get to grips with the main types of mattresses on offer, our experts have put together a quick guide to the most common varieties you’re likely to encounter on your search.
Unless you’ve been living under a rock, you’ll have heard lots about memory foam mattresses in recent years. Although originally developed by NASA for astronauts, memory foam has become an increasingly popular material of choice for making mattresses. In fact, many of the best quality king size mattress models are made from memory foam.
Memory foam is specially designed to contour to the unique shape of your body, supporting you in a way that feels quite different to a traditional innerspring. This ability to adapt to your body comes with various benefits and many people find it extremely comfortable.
However, it won’t suit everyone. So, is memory foam right for you? Let’s check out the advantages and disadvantages of this ever-popular mattress type.
• Pressure relief: A memory foam mattress can conform to your body’s curves while you sleep, relieving pressure on your joints. Why is pressure relief so important? Over time, excess pressure on your pressure points can cause aches and pains, even leading to potential joint problems over time. For this reason, memory foam mattresses can be particularly good for those with back or joint pain, or people who sleep on their sides.
• Reduced motion transfer: Unlike spring mattresses, memory foam mattresses isolate movement form one side of the bed to the other very effectively. This means that you shouldn’t be too acutely aware of your partner tossing and turning during the night.
• Durability: As a rule, memory foam mattresses tend to be pretty long-lasting and shouldn’t start to sag too quickly. Most do not need to be flipped, although you should check your manufacturer’s guidance to find out whether you should rotate your mattress to prolong its life.
• Great range available: Nowadays, there are a vast array of mattress manufacturers making high-quality memory foam mattresses in a wide range of prices. Therefore, you’ll be spoilt for choice if you opt for this as your preferred type.
• Sleeping hot: Unfortunately, traditional memory foam mattresses tend to retain heat. This can become a real problem if you live in a warm climate or tend to sleep hot anyway. However, many brands are combating this by using means to make their mattresses more breathable, such as adding air channels or infusing their foams with copper or charcoal. Check this out before you buy to make sure your mattress keeps a comfortable temperature.
• Off-gassing: Due to the chemicals used in their manufacture, memory foam mattresses can let off a funky smell when you first unpack them. This is known as ‘off-gassing’. Some people aren’t bothered by this, whereas for others it can be a real pain. For this reason, you’ll need to air out your new mattress for at least 24 hours before you sleep on it.
• Can feel tricky to move around: Some people love the feeling of sinking into a memory foam mattress. However, this can make moving around in bed feel laborious, especially if you have mobility issues.
Although less commonly used than traditional memory foam, gel mattresses have enjoyed a boom in popularity recently. Why use gel in mattresses? Well, using memory foam infused with gel can add extra support and also helps to keep the mattress cooler during the night. That’s because gel can wick away excess body heat while you sleep. Therefore, infusing mattresses with gel can help to solve some of the common grumbles with regular memory foam. So, is gel the right choice for you?
• Temperature neutral: Gel mattresses help to reduce the build-up of heat that so often happens with normal memory foam. For that reason, they can be a better choice for those that tend to sleep hot.
• Reduced motion transfer: Like regular memory foam, gel mattresses generally come with very low amounts of motion transfer. That means that you won’t be able to feel your partner fidgeting during the night.
• Pressure relief: Again, in this regard, gel performs in much the same way as regular foam. As it can conform to the shape of your body, this can help to reduce pressure on your joints. Therefore, it’s a good option for reducing bedtime aches and pains.
• Less choice available: As gel is less commonly used, you won’t be as spoilt for choice as you would be shopping for a memory foam or traditional spring mattress. However, as the popularity of gel mattresses continues to rise, we can expect this to change as more manufacturers branch out into this area.
• Off-gassing: Like memory foam, gel mattresses often let off a funny smell at first. This may not bother you. If it does, however, then you’ll need to air it out for at least a day before sleeping on it.
Nowadays, come of the best quality king size mattress models are made from latex foam. Ok, we know what you’re thinking: why on earth would you use latex to make a bed? Believe it or not, latex foam has several properties that make it ideal for mattress making. Latex foam is a supportive and adaptable material, which is able to contour to your body.
Furthermore, it’s a natural product which means it has a minimal impact on the environment. Let’s check out latex mattresses in more detail.
• Support and pressure relief: Latex foam performs well as a material for making a good quality king size mattress because it is both supportive and has the ability to conform to your body shape. This means that it encourages a healthy spinal alignment whilst relieving pressure. So, it’s a great option if you suffer from back or joint pain.
• Longevity: Latex foam is a durable material, lasting many years. So, you can expect your new latex mattress to last a long time, provided you care for it properly.
• Reduced motion transfer: Latex foam is very good at isolating movement from one side of the bed to the other. Therefore, you can sleep comfortably without being disturbed by movements from your partner’s side of the bed.
• Maybe too firm: As a rule, latex is a good material if you’re looking for the best firm king size mattress. However, for some people, latex may feel too firm to be comfortable. In the end, it all comes down to our individual needs and personal sense of comfort.
• Heat retention: Latex mattresses often retain heat more easily than some other types, which can make them uncomfortable to sleep on if you already suffer from night time overheating or live in a very hot climate. However, many latex manufacturers combat this by using air channels or convoluted layers to make their mattresses more breathable.
Those on the hunt for good king-size beds may also want to consider hybrid mattresses. You’ve probably heard of a hybrid car, but what’s a hybrid mattress? As the name suggests, these mattresses combine more than one of the above types of mattress. Hybrid mattresses usually comprise of an innerspring core wrapped in another material such as memory or latex foam. So, it’s a ‘best of both worlds’ situation, which can be a good option if you’re torn between more than one type of mattress.
• More bounce: If you’re tempted by a foam mattress but think you may miss the familiar ‘bounce’ of an innerspring, then a hybrid mattress could be the answer. That’s because the vast majority of hybrid mattresses have an innerspring core. So, you can retain bounciness whilst enjoying the benefits of body-conforming foam.
• Breathable: Provided that you’re buying a hybrid mattress with an innerspring core, this means that there are plenty of air cavities within the body of the mattress. Therefore, air can circulate, allowing heat to escape during the night. So, hybrid mattresses could be the answer if you like the idea of memory foam but want to keep cool.
• Support and pressure relief: Mattresses with innerspring cores are generally very supportive, which is good for your back health. Assuming the mattress is wrapped with memory foam, gel foam or latex foam, then the mattress will also have the ability to adapt to the shape of your body. Therefore, this also helps to relieve pressure on your body during the night.
• Less choice available: In terms of mattresses, hybrid models are the new kids on the block. So, it stands to reason that there aren’t as many manufacturers making them as many more established types. That being said, you should still have a reasonable range of choice as hybrids are becoming more mainstream. Just don’t expect to be as spoilt for choice as if you were buying a memory foam or spring mattress.
• Off-gassing: If you choose a hybrid mattress wrapped in memory foam or gel-infused foam, then you could experience some off-gassing when you unwrap your new bed. This is due to the chemicals used during manufacture. Although harmless, these can smell unpleasant, so you’ll have to air the mattress out before you sleep on it.
Chances are, you’ve spent at least some of your life sleeping on a spring mattress. You may even be using one as your current bed. That’s because spring mattresses are the most commonly used of all the mattress varieties. Although not necessarily as hi-tech as some of the other types, the truth is many of the best quality king size mattress models are spring mattresses.
Simply put, spring mattresses use a network of metal coils to provide support to sleepers. The very cheapest of these mattresses have a system of interconnected coils, as they are inexpensive to manufacture.
However, many sleepers find these cheap spring mattresses uncomfortable and also find that they transfer movement from one side to the other very easily. More popular nowadays are mattresses with individual springs, each sewn into their own fabric ‘pocket’. So, what are the pros and cons of spring mattresses?
• Breathability: Spring mattresses have plenty of air cavities inside, allowing air to freely circulate. This means that heat can easily escape while you slumber making spring mattresses a top choice for those that sleep hot.
• Lower cost: In general, spring mattresses come at a lower price than many other mattress types. However, be aware that some of the more premium brands can still come with a hefty price tag.
• Familiarity: Many people are very accustomed to sleeping on a spring mattress, and like the feeling of ‘bounce’ that they give. They also do not have the ‘sinking in’ effect which can come with foam mattresses, which some people do not like.
• Good support: A spring mattress gives a good level of support, which can be helpful for back pain and maintaining a healthy spinal alignment.
• Sagging: Spring mattresses tend to sag quicker than other types, especially if you buy a model with interconnected springs. However, you can prevent this for as long as possible by flipping and/or rotating your mattress.
• Motion transfer: Unfortunately, spring mattresses with interconnected spring systems are notorious for motion transfer. This means that your movements can be felt by your partner on their side of the bed and vice versa. However, this is less problematic with pocket spring mattresses.
• Heavy weight: Spring mattresses are usually heavier than other types of mattress. Whilst probably not a deal-breaker in itself, bear in mind that you will need someone to help you flip your mattress, or to help you move it from place to place.
Where should you buy a king-size mattress?
When it comes to buying a king-size mattress, you really have two choices as to where you buy. You can either buy from a regular bricks-and-mortar mattress store, or you can buy online.
If you choose to shop instore, the major advantage of this is that you get to try out mattresses before you commit. Many people do not like the idea of buying a mattress without having tested it first.
However, as many mattress store employees work on commission, you may be put under pressure to commit to a purchase. If you find a mattress you like in-store, it’s a good idea to see if you can find it cheaper online before you part with your money.
Many people now prefer to shop for mattresses online. There are several reasons that this might be a good idea. First of all, you’ll have access to a wider range of products that you’ll find in store. In fact, many mattress manufacturers sell their products exclusively online. Because of the wealth of online information available, you’ll find it easier to compare king size mattresses online.
There are also good deals to be had online, as selling this way is cheaper for bed companies. So, many choose to pass on these savings to their clients. On the other hand, a disadvantage is that you won’t be able to try your mattress first.
For this reason, it’s especially important to make sure your mattress comes with a sleep trial, so you can get a refund if you find it turns out to be unsuitable.
