Frequently Asked Questions
How big is an emperor mattress?
An emperor mattress measures 200 cm by 200 cm — or 6 feet and 6 inches. Emperor mattresses are as wide as they are long, meaning there’s plenty of cosy surface area to spread out and relax.
Emperor mattresses are the largest commercially available size of mattress — and even then, they are quite uncommon to see! To compare them to the second-largest size, an emperor mattress would give you an additional 20 cm of space when compared to a Super King, which is 180 cm by 200 cm. It may not sound like much, but we’re sure that you’ll notice the difference — especially if you share a bed!
In the UK, mattress sizes are as follows:
|Mattress Size||Size in feet and inches||Size in centimetres|
|Small Single||2’5” x 6’2”||75 cm x 190 cm|
|UK Single||3’0” x 6’2”||90 cm x 190 cm|
|Euro Single||3’0” x 6’6”||90 cm x 200 cm|
|Small Double||4’0” x 6’2”||120 cm x 190 cm|
|UK Double||4’5” x 6’2”||135 cm x 190 cm|
|Euro Double||4’7” x 6’6”||140 cm x 200 cm|
|UK King||5’0” x 6’6”||150 cm x 200 cm|
|Euro King||5’3” x 6’6”||160 cm x 200 cm|
|Super King||6’0” x 6’6”||180 cm x 200 cm|
|Emperor||6’6” x 6’6”||200 cm x 200 cm|
Una is one of the few mattress companies in the UK who offer emperor mattresses. We don’t believe in compromising on comfort, so made sure that our Una Mattress™ Organic Mattress Delux was available in the emperor size, as well as all the other standard UK and European sizes.
Who is an emperor mattress good for?
Emperor mattresses can be a fantastic sleep solution for taller people and couples. With a standard UK double mattress measuring only a little over 6 feet long, if you’re 5’10” or taller, you may struggle to spread out properly when you factor in things like pillows.
Emperor mattresses are fantastic for those with bigger and taller bodies, providing both the space and support that they need to sleep more comfortably. We spend roughly a third of our lives in bed, so why should you have to suffer in cramped conditions?
Space to move and stretch as we sleep is so important. When we aren’t able to do this, it can lead to issues with your sleep, your back, and possibly even your relationship. Sharing a bed can be difficult at the best of times, but when you both have less space than you need, it certainly doesn’t help.
As we mentioned above, an emperor mattress would add an extra 20 cm of width to your mattress compared to a Super King — and a staggering 65 cm more than a standard UK Double!
Why should I buy an Una emperor mattress?
At Una mattress, we pride ourselves on the craftsmanship and thoughtful design that goes into every one of our mattresses.
Many mattresses are manufactured with harmful microplastics and unnecessary chemicals, which can make their way into your home through a process called “off-gassing”. However, our mattresses are certified organic. We make them with all-natural materials like cotton and ethically sourced wool for a mattress that is good for your sleep, as well as being better for the environment.
We also use natural latex — a healthier alternative to man-made materials like memory foam. To learn more about the benefits of natural latex for your sleep and the plant, feel free to visit our organic latex page for more information. And if you’d like to shop the full range, feel free to visit our online mattress store to see all the models we have available.
