A king-size mattress is 15cm wider and 10cm longer than a standard double mattress, meaning it offers plenty of space to stretch out — perfect for taller or heavier sleepers. They’re the perfect middle ground if you like space to relax, but can't quite fit a super king-size into your room.
As well as being incredibly spacious, our king mattresses are exceptionally comfortable and supportive, allowing you to enjoy a luxurious night's rest. And, we carry this size in all of our best collections, including our Memory, Fresh, and Octaspring mattresses, so you'll be able to find the exact style that matches your sleeping needs. And, with our 60-night comfort guarantee, you’ve got a full two months to decide whether your mattress is right for you.
Should you have any questions about our king-size bed mattresses, you can get in touch with our team at [email protected] or 0800 625 0134. They'll be happy to answer your queries or provide more information.
We offer free UK tracked delivery, so order a king size mattress from our online store today. Alternatively, take a look at our European king-size mattresses, which are an extra 10cm wider. Of course, if you have enough room, you could push the boat out with a super king mattress: the largest and most luxurious size we offer. Measuring 180cm by 200cm, they’re twice as wide as a single mattress!
