Super King Mattresses & Bed Bases

Sleep indulgently with a super king mattress

Dream big and sleep expansively with a super king mattress. Offering around 20cm extra width than a regular king, these mattresses are designed for the ultimate comfort. Perfect for couples who love to sprawl, or for individuals who cherish their own space for relaxation, super king mattresses provide a lavish amount of space to snuggle up and sink into.

Super king mattress size

While a king-size mattress is already a spacious 183cm x 203cm, a super king takes luxury and comfort to the next level, measuring an approximate 203cm x 203cm. This extra 20cm width makes a noticeable difference in terms of sleeping area and comfort, providing a luxurious amount of space for stretching out and relaxing. That makes super kings a popular choice for taller individuals or couples looking to minimise partner disturbance. 

Of course, a super king mattress also requires a larger bedroom to accommodate its size, so it’s important to measure your space before purchasing a super king mattress to ensure you have enough area to comfortably move around.
