What is an Emperor size bed?

Article navigation

An Emperor bed, typically measures 7 feet square (215 cm x 215 cm). As there is no industry standard for bed sizes, some manufacturers make a slightly smaller version of an Emperor bed measuring 6’6” square (200 cm x 200 cm).

When it comes to choosing a new bed, size matters. Various studies show that couples sleep better in bigger beds because they are less likely to disturb one another. However, most couples in the UK still sleep in a standard double bed, which is only 4ft 6” (135 cm) wide. While it’s nice to cosy up with your partner in bed, this only gives each person around 2ft 3” of sleeping space, that’s less than a baby gets in a cot!

You could consider upgrading to a larger bed if you have a large bedroom. In the UK, there are six typical bed sizes, with super king measuring 6ft wide regarded as the biggest size. But what if you could go even bigger?

Emperor bed size

Some manufacturers can cater to large bedrooms by offering oversized mattresses and beds. An impressive centrepiece for a spacious bedroom, an Emperor bed typically measures 7 feet square (215 cm x 215 cm). As there is no industry standard for bed sizes, some manufacturers make a slightly smaller version of an Emperor bed measuring 6’6” square (200 cm x 200 cm).

An Emperor bed is a size up from a super king. There is plenty of room for children, pets, or just stretching out.

What are the benefits of a bigger bed?

We spend around a third of our lives in bed, so why compromise on sleeping space? Being disturbed by your partner in bed can contribute to poor quality sleep. If you’re fighting over the bedcovers, disturbing one another when you turn over in bed or taking up most of the space, it may be time to upgrade your bed.

Couples sleep better in bigger beds, and various studies support this. With a bigger bed, you’ll enjoy a more relaxing, restful, and peaceful sleep without interference. Some adults also need more sleeping space because they prefer to share a bed with children or pets.

Couples also often find that when they are used to sleeping in a bigger bed, they rarely downsize when it’s time for a replacement. So if you have the space and budget, bigger is better.

Where can I purchase an Emperor bed?

There are fewer manufacturers than can offer beds and mattresses in Emperor size because they are essentially bespoke. However, if you visit your local store, they can advise you on which beds are available as an Emperor. They may have a few models on display for you to try to help you decide which is right for you.

Alternatively, various online retailers can offer beds and mattresses in bespoke sizes. Just remember to do plenty of research to ensure the retailer is reputable.

Mattress types

There are several different types of mattresses available for an Emperor bed. It isn’t necessarily the case that one type is better, but what you and your partner find the most comfortable and supports you both correctly.

Pocket springs

Pocket springs are likely the most common option for an Emperor bed. Pocket springs are smaller, softer springs encased in fabric.

Each spring works independently, allowing the mattress to conform better to the shape of the body. Spring counts typically start from 600 in cheaper models and can go up to 10,000 springs and beyond.

Pocket springs often come in soft, medium, firm, and sometimes extra firm tensions, so you can choose the tension that suits your body weight and preference.

Memory foam

Memory foam moulds and adapts to the shape of the body, distributing your weight more evenly. The material has good pressure-relieving qualities that can help sleepers who suffer from back and joint pain. 


Natural latex is a durable material that is produced from the sap of the rubber tree. Like memory foam, it offers good pressure relief and even weight distribution across various sleeping positions.


A hybrid mattress is typically a combination of foams and springs. It offers the perfect compromise for many sleepers combining the support of a traditional sprung mattress with the comfort and cushioning benefits of different foams.

Bed bases

An Emperor mattress is typically paired with a divan or bedstead. It’s vital to ensure that the two are compatible, especially when buying both separately.

A divan base is an upholstered box with a solid top or spring unit for the mattress to rest on. Divan bases come in various colours and materials and can sometimes be paired with a matching headboard.

Divan bases can often include drawers providing extra storage for light items like books and bedding. The four-drawer continental option is ideal for rooms with bedside cabinets. This configuration features two smaller drawers on either side at the head of the bed that open and close without having to move the bedsides.

Alternatively, you may prefer four standard-size drawers to maximise storage space or an end drawer which opens from the foot of the bed. Whatever combination you choose, make sure you allow extra bedroom space so you can open the drawers.

Bedsteads or bed frames typically occupy more space because the mattress often sits inside a frame. Bedsteads come in various styles to suit traditional and modern room settings. The frames are available in wood, metal, fabric, or leather. But keep in mind the options may be limited for bespoke sizes.

Most bed frames come with solid or sprung slats to support the mattress.

Zip and link

Large mattresses can be extremely heavy and difficult to move, even with generous access to the bedroom. Carrying an Emperor mattress requires a lot of physical effort making the delivery process a daunting experience.

Because of this, most Emperor beds usually come with a zip and link mattress for ease of transport and easier access to the bedroom. Zip and link allow two separate mattresses to be zipped together, creating one large mattress. Separate mattresses are much easier to manoeuvre than a one-piece mattress. Not only does this help with the delivery process, but it is also much easier to turn and rotate two single mattresses where necessary.

If you pair the mattress with a divan, the divan will come in two or four sections. Once in situ, the sections can be discreetly linked together. Another benefit of a divan is that it also provides the flexibility to split one large bed into separate beds when needed.

Memory foam and latex mattresses are generally unavailable as zip and link due to the materials’ flexibility. But you can order two separate mattresses instead and push them together. You could use a snug, fitted sheet to keep both mattresses together, but this is not as effective as zipping and linking.

Bed frames usually come flat-packed in several sections, which often include the headboard, footboard, side rails and slats.

Measure the space

When buying a bigger bed, such as an Emperor, you will want to ensure it can fit into the room comfortably and that there is sufficient room to move around the bedroom once the bed is in place.

You also need to check access points like stairs and doorways to avoid problems with delivery. Remember that Emperor beds are made to order, and the store you purchased the bed from may not accept returns in the event of a failed delivery.

Where do I find bedding for an Emperor bed?

You should be able to find bedding for an Emperor bed online though it won’t be as freely available as standard bedding. You may also have to wait longer than usual for delivery as the bedding will be typically made to order.

Mattress turning

Most mattresses require turning to help even out the wear. People are often concerned about turning a larger mattress due to the physical effort involved.

Fortunately, an Emperor bed often comes with two separate mattresses, making mattress turning much easier. Some mattresses are single-sided and cannot be flipped over for sleeping on. Non-turn mattresses only need to be rotated from time to time.

Other mattresses may be referred to as being no need to turn. These mattresses are double-sided and can be flipped and rotated occasionally where necessary.

Is there a bigger bed than an Emperor?

In America, an Alaskan king bed measures 9 feet by 9 feet and is the largest bed available, while an Alberta king measures 8 feet by 8 feet. Both beds are ideal for larger couples or families that share the bed with their children.

Final thoughts

Partner disturbance is one of the main reasons for poor sleep, so buying a bigger bed should result in a better night’s sleep. Because there is no UK standardisation, bed sizes may vary between manufacturers, so if you’re considering an Emperor bed, confirm the size with the retailer beforehand.
