What size is a super king mattress?

A super king size mattress measures 6 feet wide (180cm) and 6 feet 6 inches long (200cm), making it the perfect mattress for those with a little extra floor space in their bedroom and a desire to get really comfortable in their bed. Whether you move around a lot at night time, like to sprawl out or just want to sit cosily in the middle of a huge bed, the super king size mattress is for you. The depth of your super king size mattress will depend on which mattress you choose, whether that be pocket sprung, memory foam, soft or firm, but the length and width will always be the same.

How heavy is a super king size mattress?

Being the largest standard mattress size means that super king size mattresses are quite heavy, although the weight of your mattress will depend on the type of mattress you choose. You can expect your mattress  to weigh roughly between 130 pounds (59kg) and 180 pounds (82kg).

What is the best super king size mattress?

The best super king size mattress for you will depend on your own body type and preferences. If you have spinal or neck issues, then a pocket sprung super king size mattress might be best for you, but if you want a mattress that is supportive and moulds to the contours of your body, then a firm super king size memory foam mattress might suit you better. If you’re looking for the ultimate in mattress comfort, then check out our 6’0” Super King Blenheim VIP 35000 Mattress.
