Super king size mattresses

Super king size mattresses are W180cm x L200cm (6 feet wide x 6 feet 6 inches long), wider than a standard king size mattress by 30cm (1 foot) offering ample space for an undisturbed, peaceful sleep.

Super king mattresses are 180cm wide or 6 foot 6 inches across with a length of 6 feet or 200cm. Full a full list of mattress dimensions, visit the size guide.

We offer a range of super king size mattresses with a spread of budget ranges available. When it comes to quality, we have exacting standards when it comes to craftsmanship, fillings and support. Our most luxurious super king mattresses have various tensions to choose from, the finest fillings and are available as zip & link mattresses too.  Read our mattress guide to help you decide which is the best mattress for you.

Standard pillows leave a noticeable gap across a wider bed frame. Super king pillows span the entire width when placed side by side, creating a balanced visual proportion and complete head support. Standard pillows function well, but super king pillows are ideal.

Luxury mattresses with deep natural fillings or integrated pillow top layers feature a higher profile than standard mattresses. Extra-deep fitted sheets (typically 32cm to 40cm depth) allow the internal natural fibres to expand fully without compressing the cushioned surface.

Rotate your mattress regularly during the initial months to encourage natural fillings to settle evenly. Turn double-sided models according to seasonal care guidelines, and protect the damask cover with a breathable mattress protector. Learn more guidance in our mattress care guide. 

Crafted with hand-tufted natural fillings and resilient steel pocket springs, a luxury super king size mattress maintains its structural integrity and support profile for ten years or more when maintained with regular rotation. We recommend consulting our mattress lifespan guide for expert advice on preserving the longevity of your investment.
