Our Super King Isn’t Made From a Piece of Heaven, but It Does Feel Like It Is.

The Super King is the King of mattresses. This is because doubles are just right for one to two people. The Spinery’s Fitzwilliam double is slightly smaller than our king and super king mattress, but it delivers the same quality sleep as its larger brothers and sisters.

Our Fitzwilliam Mattress uses only quality materials.


Our Super King size mattress is crafted using the highest quality foams and fabrics. Our Super King size mattress is made from 100% natural and plant-based materials which means it’s safe for you and the environment.

Intelligently Engineered Contouring by Our Team of Doctors Means ‘Just Right’ Support

We use perforations and multiple layers of distinct natural latex foam. This gently supports your body while cradling your weight; this relieves stress and pressure from your back.

Our design also means that you maintain perfect alignment through your night, allowing your body to recover in a tension-free position.

What Is the Dimension of a Super King Bed and Mattress?

Our Super King beds are 180cm wide and 200cm long. If you are familiar with imperial dimensions, this equals 6 feet in width and 6 feet 6 inches in length. Since its the most massive bed and mattress size available, this means an unbeatable amount of space for sleep.

Best For: If you value a lot of space or your family all like to squeeze in together on some nights, the super king is a perfect choice.

Some of Our Super King Mattress Reviews

Ivan Flynn


Really happy with the mattress and pillows. The kids are sleeping much better too, and definitely have more energy in the morning!


David McClelland 


Best purchase I ever made. Sleep like a baby now.
I also got the pillow. Never use anything but Latex again.

James Maguire


Very pleased with mattress. No unpleasant odors, it’s nice and firm but has a nice soft feeling to it. My sleep has improved exponentially ever since I replaced my old pocket spring coil mattress with one of these Spinery latex mattresses. Best purchase that I made all year!
