Why choose a Super King Size mattress?

If you want a large mattress then the Super King mattress is the obvious choice – with the largest measuring 6ft in length. There are so many benefits in choosing a Super King Size mattress. Here, we’ll take a look at some of the key reasons to choose super king:

Extra sleeping space

With a super king, you can expect extra sleeping space and a restful night’s sleep – ideal if you or your partner tend to shuffle around in your sleep. Measuring 6ft in length, super king mattresses are a whole foot longer than a standard king size mattress.

Extra space for tall partners

If you or your partner is tall, then this size is the obvious choice. As you’d expect, they’re the longest mattress available, ideal for those taller than 6ft. If you want a mattress that really ensures that you do not disturb your partner, then opt for a pocket sprung or memory foam Super King mattress, or a combination of both as these are designed to cope with different weights and movement, resulting in a mattress that will not dip or sag.

A wide range of materials and fillings

Super-king mattresses are available in a range of depths, comfort levels, and fillings to suit every preference. We also provide a huge range of materials including cotton, cashmere, lambswool, silk and even latex to name a few! Super king latex mattresses work in the same way as a super king memory foam mattress but are a more affordable option. So, if you want lots of space, extra comfort, all at a great cost, consider a super king latex style.

What is the best super king mattress?

The best super king mattress will come down to personal preference. Depending on the level of firmness you prefer, you might find one type of mattress – from hybrid to innerspring to foam – more comfortable than another. To find the best super king mattress consider the following:

  • Whether you normally sleep on your back, front, or side
  • What your budget is
  • Whether you suffer from lower back pain
  • If you are sleeping alone or with a partner
  • How much you weigh

Once you’ve thought about these considerations, take a look at the firmness and material specifications on each product to decide which is the best model for you. We offer a whole host of super king bed and mattress deals!
