Super Kingsize Firm Comfort Mattresses

A super kingsize bed and mattress is the largest UK standard size and provides ample space for two sleeping adults. Measuring 180cm wide and 200cm long or 6 feet wide and 6 feet 6 inches long, the super king is the largest of all standard UK sizes. The super king (6’0”) sized bed provides abundant space.


A firm mattress is a firmness that offers very little give or sink, providing a very supportive sleeping surface and distributing your body weight more evenly than softer mattresses. Firm mattresses are perfect for front and back sleepers.
