Our goal is to assist you in finding the perfect king size mattress for a peaceful night's sleep.

When looking for a mattress, everyone has different requirements. Your body shape, weight distribution, firmness preference and mattress type are all factors that determine which mattress is for you. 

Explore the collection of mattresses we have available at The Bed Warehouse Direct, and get in touch with our team on 0800 049 0800 if you have any questions about the mattresses we offer.

What is a king size mattress?

A king size mattress is a type of mattress that is larger than a standard double mattress. They are usually 5’0” wide by 6’6” long, which makes them perfect for a couple, especially if someone in the couple requires those extra few inches to fully stretch out.

In order to fit a king size bed into your bedroom, you’ll have to have plenty of space to ensure that your bed fits where you want it to go. It’s a good idea to measure the space where you’d like your bed to go before purchasing it, to avoid disappointment if your bed doesn’t fit when it arrives.

How big is a king size mattress?

A king size mattress is 5’0” (150cm) wide by 6’6” (200cm) long.

We also stock a range of king size bed frames that are designed to fit our collection of king size mattresses.

What other mattress sizes do you have available?

If you’d like to explore the other sizes of mattresses we have available, we offer a variety of different options for you to consider:

What types of king size mattresses do you stock?

We offer a wide range of king size mattresses that are crafted using a combination of traditional and modern methods, as well as automated techniques. This ensures that our king size mattresses are of high quality, and you can explore the different options we have available below:

King size open coil mattresses: These are made using individual steel coils that are connected to each other and reinforced with a thicker gauge steel for added firmness. However, it's worth noting that while some people may find these mattresses beneficial for back support, it may not be the case for everyone.

King size pocket spring mattresses: These are composed of individual steel coils that are encased in fabric. This design allows each spring to move independently, providing customised comfort and support that conforms to the sleeper's body shape.

King size memory foam mattresses: This is a great choice for those looking for a comfortable and responsive surface. These mattresses are created by bonding together various types of foam to reduce pressure points. However, one common issue with traditional memory foam mattresses is that they tend to trap heat, making it hard for some users to move around comfortably. But, the good news is that manufacturers have come up with solutions such as incorporating cooling foam or latex-based foam layers to address this issue.

King size hybrid mattresses: This is designed to give you the best of both worlds, combining the traditional benefits of spring mattresses with the modern technology of memory foam. This creates a versatile and comfortable sleeping surface that is sure to provide you with a great night's sleep. This hybrid mattress is a great option for those who want the support of a spring mattress as well as the pressure relief of a memory foam mattress

What's the best king size mattress for my sleep position?

The best king size mattress for you will depend on your preferred sleep position.

Front sleeper

If you're someone who sleeps on their front, it's crucial to choose a firm king size mattress. This is because a soft mattress can cause your hips to sink too far, resulting in lower back pain. 

It's worth noting that sleeping on your front can be a sign of a pre-existing lower back condition, so if possible, it's best to avoid this position. However, for those who can't change their sleeping position, a firm mattress is an essential choice to help alleviate any discomfort.

Back sleeper

For those who sleep on their back, a medium-firm king size mattress is the ideal choice. This type of mattress should be firm enough to keep your hips in alignment, but also soft enough to adapt to the curve of your lower back, providing a perfect balance of support and comfort. 

A medium-firm mattress will help keep your spine in a neutral position and reduce any pressure points, making for a comfortable and restful night's sleep.

Side sleeper

For those who sleep on their side, having a responsive mattress is essential. A mattress that allows your hips and shoulders to sink in while still providing support for your waist is ideal. 

Depending on your body shape, a soft king size mattress may be the best choice.

This type of mattress will conform to your body and provide the needed support for your hips, shoulders, and waist. It will also help to reduce pressure points, allowing for a more comfortable night's sleep.

How much does a king size mattress cost?

When it comes to purchasing a new king size mattress, it's important to remember that investing in a quality product can have long-term benefits for both your physical and mental health. 

Assuming a new king size mattress lasts around 8 years with 2 people sleeping on it, even a higher range king size mattress from £500 would be costing each sleeper from as little as 9 pence per night.

A middle range king size mattress costing between £200 and £500 would work out at between 3.5 pence and 8.5 pence per sleeper per night.

If you were to buy a cheap king size mattress for less than £200 that could be as low as just 2 pence per night per person.

How do I choose the right king size mattress for me?

It's crucial to figure out what level of comfort you're after when looking to purchase a new king size mattress. 

Take a moment to think about what you liked about your old mattress when it was new, and what you wish you could change about it now. It can also be helpful to think about a time when you slept exceptionally well on holiday and try to replicate that mattress's feel.

It's also important to consider how your own body shape and weight will affect your mattress choice. Keep in mind that product descriptions and firmness guides are based on average body types, so a mattress that feels comfortable for one person may not feel the same for someone else with a different body shape or weight.

Don't hesitate to take a look at the resources available on our website such as our FAQ videos, Bed Buyer's Guide, and our blog. We've tried to provide as much information as possible to help you make the important decision of choosing the best mattress for you.

If you're still unsure about which mattress to purchase, our expert team is here to assist you. You can give us a call at 0800 049 0800 during business hours (9:30am - 5:00pm) or drop us an email, and we'll get back to you. Our advisors have extensive experience and will provide friendly, honest, and highly-skilled advice without any pressure to buy.
