A super king size mattress offers the ultimate in both comfort and space. These larger mattresses give you more room whilst sleeping throughout the night. This means that you get excellent support from one of our super king size mattresses alongside the comfort of high-quality sleep.
Our super king size mattresses measure 180cm x 200cm / 6ft x 6ft6, making them roughly 30cm / 12 inches larger than a regular king size mattress. To find out more about the difference in mattress sizes, take a look at our Mattress Size Guide.

Everyone sleeps differently. So, we’ve made sure that we stock a range of super king size mattresses that can accommodate your sleeping preferences.

Side sleepers may wish to choose a soft mattress that will allow their bodies to sink into the material. On the other hand, back sleepers will benefit more from a firm mattress that provides increased back support.

To help you choose the super king size mattress that suits you best, utilise our firmness tool. Simply enter the weight and firmness preferences of the people who will be using this new mattress, and a handy scale will be shown for each product to show how it will feel under body weight.

Check it out! It’s the dark blue box on the left-hand side of this page.

To ensure complete satisfaction, we stock a range of super king size mattresses, including:

  • Reflex Foam Mattresses - crafted with high-density polyurethane material. It adds firmness to different areas of the mattress to accommodate different sleeping positions.
  • Orthopaedic Mattresses - firmer than standard mattresses, our super king size orthopaedic mattresses can better support your lower back while you sleep, allowing you to maintain a good posture.
  • Pocket Sprung Mattresses - filled with separate pocket springs. These springs help create an evenly distributed sleeping area for increased comfort and stability during sleep by operating individually.
  • Rolled Mattresses - regular mattresses that are delivered in rolled-up This allows them to be delivered and transported much more effortlessly.
  • Open Coil Mattresses - made up of high-tension steel coils. A wire connects these coils, which run parallel to one another. Because open coil constructions are firmer, they are commonly used in orthopaedic mattresses.
  • Latex Foam Mattresses - is made from the sap that is gathered from rubber trees. It is a highly desirable material for mattresses as it’s durable and hypoallergenic – perfect for those who suffer from nighttime sniffles! Latex foam is more breathable than memory foam because it allows air to flow more freely through it.
  • Memory Foam Mattresses - conforms to your body’s shape to provide a tailored sleep that matches your natural sleeping position.
  • Kids Mattresses - these mattresses use slightly less filling to save money and accommodate smaller bodies.
  • Bunk Bed Mattresses - Bunk bed mattresses are thicker than traditional mattresses to compensate for both size and an elevated sleeping position.
  • Trundle Mattresses - offering excellent storage abilities thanks to their small footprint and another space for guests to sleep.
