Super king size mattresses are the definition of luxury. If you love space, comfort, and that five-star hotel feeling at home, this is the size for you. With plenty of room to stretch, turn, and relax, a 6ft super king mattress transforms your bedroom into a haven of peace and rest.
At our UK store, we stock a wide range of super king size mattresses, from premium pocket sprung and supportive orthopaedic designs to indulgent memory foam and hybrid models. Every mattress is built with high-quality materials to ensure lasting comfort, reliable support, and years of restful sleep.
This is more than just a mattress. It’s an upgrade to your lifestyle — perfect for couples who value space, taller sleepers who need extra length, or anyone who simply wants the best night’s sleep possible.
A super king bed mattress size measures 6ft x 6ft 6in (180cm x 200cm), making it the largest standard mattress size in the UK. It’s a full 30cm wider than a king size, offering more space for two people to sleep comfortably without disturbing one another.
If you’ve ever felt cramped on a double or king, the extra width makes a world of difference. There’s room to spread out, roll over, or sleep in any position you like — all without bumping into your partner.
This mattress is ideal for master bedrooms, large loft spaces, or any room where space allows you to truly enjoy it. Always measure your bed frame and doorways before ordering, as super king size mattresses are both wide and deep, and you’ll want to ensure smooth delivery and setup.
Owning a 6ft mattress isn’t just about size, it’s about improving the quality of your rest and wellbeing. Here are some of the biggest benefits:
More space for better sleep: The wider sleeping surface gives each person more room to move, reducing tossing and turning.
Perfect for couples: You won’t feel your partner’s movements, so both of you can enjoy an uninterrupted night’s sleep.
Ideal for taller people: At 200cm long, it gives extra legroom for taller sleepers who often find standard beds too short.
Luxurious comfort: Larger mattresses often feature extra layers and deeper fillings for added plushness and support.
Family-friendly: Great for parents whose children or pets like to climb into bed for a morning cuddle.
Once you’ve slept on a super king size mattress, it’s hard to imagine going back to anything smaller.
