Need a little extra room? We’ve got the perfect choice for you. Get a great sleep night after night on a Dormeo King Size memory foam mattress; designed to offer you room to find your perfect sleeping position. Our fantastic range of standard-sized King mattresses (150x200cm) are roomier than a standard double but still provide the same level of comfort and support. Shop the range below to find your perfect king-size mattress for you!
At Dormeo, we’re dedicated to delivering comfort, and our king-size mattresses are spacious, supportive, and stylish, making them the perfect ally for a good night’s sleep.
Our European king-size mattresses are an extra 10cm wider. Of course, if you have enough room, you could even 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!
Need extra support? We’ve got your back. Our king-size mattresses are available in Memory, Fresh, and Octaspring, and even traditional pocket-sprung mattresses so you can find the ideal style for your sleeping needs. And with our 200-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.

What size is a king-size mattress?
Ideal for taller or heavier sleepers, king-size mattresses are a spacious alternative to standard double mattresses, which typically measure 150cm wide by 200cm long.
So, if you like a little extra luxury but don’t have space for a super king-size, a king-size mattress offers a neat middle ground.
What are the dimensions of a standard king-size mattress?
A standard king-size mattress is 150cm by 250cm, making them ideal for mid-to-large size rooms.
How much bigger is a king-size mattress than a queen-size mattress?
In short, quite a bit! King-size mattresses are 30cm wider and 10cm longer than a small double mattress (otherwise known as queen-size).
We recommend that you don’t attempt to fit a king-size bed on a queen-size frame.
Can a king-size mattress fit on a double bed?
We’d avoid it. Given the size difference between a king-size mattress and a much smaller double bed, it’s best to only put king-size mattresses on king-size frames.
If you’re looking to upgrade your sleeping set-up with a king-size mattress, go the extra mile and choose from our premier king-size bedding range, including pillows, duvets and sheets, or add a mattress topper for ultimate comfort.
How much is a Dormeo king-size mattress?
We’re dedicated to delivering a quality night’s sleep at an affordable price, so we offer a wide range of king-size mattresses to suit all budgets.
What is the best king-size mattress for me?
That depends entirely on your sleeping position. If you’re a side sleeper, you’ll likely be more comfortable on a softer mattress, or if you want to really appreciate the extra space a king-size mattress offers by sleeping on your front or back, you may prefer something firmer.
If you’re one-half of a couple with drastically different sleeping positions, we’d recommend a medium firmness mattress.
