A super king size mattress measures 180cm x 200cm / 6ft x 6ft6, roughly 30cm / 12 inches larger than a regular king size mattress . Want to find out more about mattress sizes? Take a look at our mattress size guide .

Our super king mattresses come in a range of firmness levels, ensuring we have a mattress that will suit every sleeper. These firmness ratings include:

• Soft super king size mattresses
• Soft/medium super king size mattresses
• Medium super king size mattresses
• Medium/firm super king size mattresses
• Firm super king size mattresses

The firmness rating of a mattress is essential, as it can dictate how supportive and comfortable it is for different sleepers. Heavier people will benefit from a firmer mattress, whereas lighter people will find a softer mattress more comfortable. Your sleeping position also impacts the firmness level of the super king mattress you will need.

Check out our guides on the best mattresses for side sleepers and the best mattresses for front sleepers to make sure you get the correct firmness rating for your position. We guarantee that figuring out which firmness you need will make sleeping better than ever. In addition, make sure to use our mattress firmness tool, which allows you to input the weight of the sleepers who will be using the mattress to give you the perfect mattress.

We have a variety of super king mattresses available to buy in our most popular types, including:
