Frequently Asked by Our Customers
What size is a super king mattress?
In the UK, a standard super king-size mattress measures 180cm wide by 200cm long, or 6' x 6'6". A full 45cm wider than our standard double mattress, 60cm wider than a small double mattress, and twice as wide as a single mattress, a super king mattress is ideal for couples who like to have plenty of space.
Each super king-size mattress benefits from our innovative design and quality craftsmanship, delivering unparalleled levels of comfort and support for your sleep. We make these products in all of our leading styles, including memory foam, pocket sprung, latex, and hybrid mattresses. You can enhance the experience of falling asleep on one of these mattresses further by adding some of our super king bedding or a super king mattress topper.
What is the difference between a king and super king?
The only difference between a king and super king mattress is that the latter is an extra foot wider. This makes them perfect for taller people or those who sleep more soundly with extra room.
Will a super king bed fit in my room?
We recommend a super king bed for rooms no smaller than 3m x 3.5m. This will give you plenty of space to fit bedside tables either side, while leaving space to move around the rest of the room.
If you’re looking for a smaller style, our European king-size and king-size mattresses are a little narrower, but still offer a generous amount of room to stretch out. We also have other mattress sizes on offer, including single, small double, and double mattresses, so you're bound to find the perfect size for your needs.
