Emperor Mattresses FAQ

How big are emperor mattresses?

Emperor mattresses are 7’0’ wide and 6’6” long. Most of our handmade wooden beds are also available in emperor size, but the footprint of our beds is always bigger than the equivalent sized mattress because the mattress sits within the bed frame.

Yes. Caesar mattresses are the next size up from emperor and they are 8’0″ wide and 6’6″ long. Eastern king mattresses are the next smallest size and they are 6’6″ wide and 6’6″ long.


A large mattress would be anything from super king-size. We would recommend a zip-link mattress for this size to ensure our delivery and installation team can get the mattress up your stairs.

Having a zip-link mattress also means it’s not too heavy, so you’ll be able to rotate it easily. A zip-link emperor mattress would be two mattresses that zip together in the middle (2 x 3’5” wide by 6’6”).

Our collection of handmade caesar bed frames will fit any caesar mattress (standard UK size).

However, all our caesar beds are bigger than 8’0″ wide because the mattress sits within the bed frame and the dimensions are dependant on the design.

For example a caesar Maine bed is 2650 (W) x 2155 (L), while our Ambassador caesar four poster bed measures 2689 (W) x 2294 (L).

It’s also important to consider furniture for bigger beds and making sure everything is in proportion. For example, our 2 over 2 chest can be used as a bedside cabinet and we can also change the width, length and height of our bedroom furniture to coordinate perfectly with bigger beds in large bedrooms.
