6' Superking Mattresses

What Size is a 6ft Super King Mattress?

A 6'0 super king mattress is the largest of all standard UK mattress sizes, measuring 180cm x 200cm (6 feet wide by 6 feet 6 inches long). That’s a whole foot wider than a king size, offering ultimate space, comfort, and luxury.

The UK super king mattress size is a perfect fit for larger master bedrooms and anyone who refuses to compromise on sleeping space. Whether you’re a couple who values undisturbed rest, a taller sleeper who needs the extra legroom, or a family that occasionally shares the bed with kids or pets, a 6ft mattress provides unmatched freedom of movement.

Who is a Super King Mattress Best For?

The super king mattress is the gold standard for:

• Couples who want ample space and less motion transfer
• Taller individuals needing maximum length
• Luxury Master Bedrooms where comfort is key
• Families who often co-sleep with children or pets
• Restless Sleepers who like to spread out and switch positions
  

While it’s a large size to squeeze in, the comfort benefits more than make up for it , as long as your room can accommodate the size and you’ve measured hallways and stairs for access!
