A full 45cm bigger than our standard 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.

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. Not sure what’s right for you? Our mattress and bed size guide has all the answers. Plus, with our 60-night comfort guarantee, you’re always free to change your mind if you’re not completely happy with your new mattress. Simply send it back and you’ll receive a full refund or exchange.

Feel free to get in touch via [email protected] or 0800 625 0134 if you have any questions about our super king mattresses. We offer free tracked UK delivery with all orders, so be sure to shop for your ideal super king-size mattress with us today.
