Article navigation

Who would benefit from an Emperor bed?

When choosing a new bed, size matters. Studies suggest that couples sleep better in bigger beds because they are less likely to disturb one another. Despite this, most couples in the UK sleep in a standard double bed, which is only 4 feet 6 inches (135 cm) wide. This only gives each partner 2 feet 3 inches of sleeping space, less than a baby gets in a cot!

Emperor beds are ideal for those sharing a bed with their partner, children or pets. There’s plenty of room to stretch out, allowing sleepers to enjoy a more relaxing, restful, and peaceful sleep without disturbances.

Couples often discover that once they’ve experienced a larger bed, they rarely downsize when it’s time for a replacement. Therefore, a bigger bed is usually a good option if you have the space and budget.

What are the different types of mattresses available for an Emperor bed?

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 mattresses

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 well to 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 spring tensions, so you can choose the firmness that suits your body weight and preference.

Memory foam mattresses

Memory foam moulds and adapts to the body, distributing your weight more evenly. The material has good pressure-relieving qualities that may help sleepers with back and joint pain. 

Latex mattresses

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

Hybrid mattresses

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.

What types of bed bases are available as an Emperor?

Typically, there are two types of bed bases suitable for an Emperor mattress – a divan or a bedstead.


A divan base is an upholstered box with a solid top or spring unit for the mattress to rest on. They come in various colours and materials and may include a matching headboard. Some divans offer a sprung base for added luxury.

Many divan bases feature drawers, providing convenient storage for items like books and bedding. The four-drawer continental option, with two smaller drawers on each side at the head of the bed, is ideal for rooms with bedside cabinets. Alternatively, you can opt for four standard-size drawers or an end drawer that opens from the foot of the bed. Ensure you allow extra bedroom space to access the drawers easily.


Bedsteads or bed frames typically occupy more space as the mattress often sits inside the frame. They come in various styles to suit traditional and modern room settings. They are available in wood, metal, fabric, or leather. However, options may be limited for Emperor sizes. Most bed frames come with solid or sprung slats to support the mattress.

The bed base you choose will affect how the mattress feels and performs. You also need to ensure the base is compatible with your mattress. Otherwise, it may not provide adequate support.

Are Emperor beds expensive?

Larger beds like Emperors tend to be pricier than standard models due to several factors. They require more materials, including extra fabrics, fillings, and springs. Emperor mattresses often feature luxurious materials like wool, horsehair, and latex, which are more costly than synthetic alternatives. Additionally, zipping and linking the mattress adds to the overall cost.

Constructing bigger beds involves more labour and a longer manufacturing process than standard models. Also, you may need to consider additional costs, such as larger bedding or a new headboard.

While Emperor beds may come at a higher price, their additional sleeping space can positively impact sleep quality. With ample room for you and your sleeping partner, there’s less chance of disturbing each other during the night.

Where can you buy an Emperor bed?

Fewer manufacturers offer beds and mattresses in Emperor size because they are essentially bespoke. However, your local store can guide you on available options and may have models on display for you to try.

Alternatively, several online retailers offer beds and mattresses in bespoke sizes. Just make sure you research beforehand to ensure the seller is reputable.

How do you find bedding for an Emperor bed?

While bedding for an Emperor bed is available online, it won’t be as widely available as standard bedding. Additionally, you may experience longer delivery times, as Emperor size bedding is usually made to order.

How does an Emperor bed fit into the bedroom?

Once you’ve established that an Emperor bed is the right size, the next step is to ensure it will fit into your intended room.

Large mattresses can be heavy and difficult to move, making the delivery process daunting. Furthermore, most Emperor mattresses won’t fit up the stairs as a one-piece, even with generous access to the bedroom.

Because of this, most Emperor beds typically feature a zip and link mattress for convenient transportation and easier access to the bedroom. Zip and link mattresses enable two separate mattresses to be zipped together, forming one large mattress. This setup makes manoeuvring much easier compared to a single-piece mattress. It is also easier to turn and rotate two single mattresses if necessary.

Emperor bed bases usually come in sections for easier access. Divans come in two or four sections, which you can link together once in place. Divans also offer the flexibility to split one large bed into two separate beds if necessary.

Memory foam and latex mattresses are typically unavailable as zip and link due to the flexibility of the materials. However, you can order two separate mattresses and push them together. Using a snug, fitted sheet to keep both mattresses together is an option, though less effective than zipping and linking.

Bed frames usually arrive flat-packed in several sections, including the headboard, footboard, side rails, and slats.

When buying a larger bed, like an Emperor, carefully measure your property, including access points like stairs, doorways, and corridors, to prevent delivery problems. Also, ensure there is enough room to move around the bed once it’s in situ.

Should you turn an Emperor mattress?

Most mattresses require turning to help even out the wear. Since Emperor mattresses are usually zipped and linked, turning should be easier. Most Emperor mattresses are double-sided, allowing you to flip or rotate them where necessary. Others are single-sided, where they can be rotated but not flipped over. Always refer to the manufacturer’s instructions before turning your mattress. Note that you need to unfasten the zips before turning.

Is there a bigger bed than an Emperor?

In America, an Alaskan king bed measures 9 feet by 9 feet, making it the largest available bed. In comparison, an Alberta king measures 8 feet by 8 feet. Both are great options for larger couples or families who share the bed with their children.

Final thoughts

Investing in a bigger bed like an Emperor can promote better sleep quality, reduce partner disturbance and improve comfort. Remember, Emperor bed sizes vary between manufacturers, so double-check the dimensions before purchasing.
