6'0 Super King Mattresses

Super king size mattresses are the largest standard size mattress we offer, and are brilliant if you need some extra space. We offer many of our most popular mattresses in super king size, giving you lots of choice from top brands like Sealy, Silentnight and Hypnos and assuring you a fantastic night’s sleep!

If you share a bed with a partner, you need to give yourself enough room to sleep comfortably without disturbing each other, so a super king size mattress is the perfect choice, giving you a whole extra foot of room than a king size mattress. Even better is a pocket sprung or memory foam super king size mattress, as these are both designed so that you won’t disturb each other as you move about during the night. You can even get a combination of memory foam and pocket springs in your super king size mattress!

If you prefer natural fillings, we have super king size mattresses stuffed with some of the most luxurious fillings nature has to offer, including breathable cotton, cosy lambswool, and soft cashmere and silk. Other super king size mattresses have latex, a brilliant new filling that has similar properties to memory foam, or man-made fibres, used in many budget super king size mattresses as a durable, comfortable filling that keeps costs down.

Use our filters to narrow down our full range of super king size mattresses, and if you need any help, give our friendly customer services team a call on 0333 577 5773
