What size is a super king size mattress?

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 .

What firmness ratings do super king mattresses come in?

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.

What types of super king size mattresses are available?

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

Super king orthopaedic mattresses

Orthopaedic mattresses are often firmer than other types, as they are designed to help alleviate lower back pain by encouraging a correct spinal alignment throughout the night. A super king size orthopaedic mattress can do this whilst giving you plenty of space to sleep!

Super king memory foam mattresses

Looking for custom support, even in a mattress as big as a super king? Look no further than a super king size memory foam mattress , which uses high-tech memory foam created by NASA that uses your body heat to contour to your body for personalised support.

Super king pocket sprung mattresses

A super king mattress is great for couples, as its large size means you're less likely to be woken up by movement. If you want to get the ultimate sleep, then invest in a super king size pocket sprung mattress as these have thousands of individually wrapped pocket springs that work independently of each other to reduce movement.

Super king open coil mattresses

Go back to the classics with a super king size open coil mattress , also called a traditional mattress or Bonnell spring mattress. This features an interlinked series of springs inside the mattress that distributes your weight evenly across the bed.

Super king latex foam mattresses

Latex foam mattresses are a great choice if you're looking for something that will offer custom support and is also hypoallergenic. A super king size latex foam mattress features naturally sourced latex foam that contours to your body, giving you high levels of support!

Not sure which mattress type will suit you best? Make sure to read our mattress buying guide to figure out which one suits you best.

How much does a super king size mattress weigh?

There is no specific weight for super king size mattresses, as they will vary depending on the mattress type. A mattress with mostly foam is likely to weigh less than a mattress with multiple layers, but the exact weight will depend on the mattress. It's important to ensure that your bed can accommodate the weight of a super king size mattress, so double-check this before purchasing!
