Introducing our collection of King Size Mattresses, one of the most spacious mattress options available in the UK. Our king size mattress collection boasts a luxurious sleep for two people or gives one sleeper a huge amount of space to stretch out across all night long. King size mattresses are available in many different types to choose from, so we appreciate how difficult mattress shopping can be, even when you’re set on the size you want. That’s where we come in. Bensons for Beds are here to help you choose the right king size mattress for you. From snuggly king size memory foam mattresses that provide a dreamy surface that hugs you good night, through to extra firm orthopaedic king size options to help relieve back pain, we’ll help you choose the mattress your dreams are made of.
Popular with people who like a little more room to move about in bed, king size mattresses are the second largest mattress size available in the UK.
A king size mattress size is 5 feet wide and 6 feet 6 inches long, or 150cm by 200cm.
King size mattresses are a foot smaller than a super king size mattress in terms of their width and whole six inches wider than a double mattress.
If you’re looking for plenty of space while you sleep or you share a bed with your partner, then a king size mattress could be a great option for you.
A king size bed and mattress is also a good option if the kids like to get in bed with you in the middle of the night. Or perhaps you like to have your pets snuggled at the foot of the bed. There’s plenty of space for everyone!
No, a king size mattress won’t fit on a double bed – it will be too big. A double mattress is the perfect fit for a double bed. So, if you already have a double bed, why not check out some of the different types of double mattresses we have available?
The depth of a king size mattress differs from one to the next. Different products, manufacturers, and styles will ultimately have different king size mattress depths. If you’re wondering about the depth of a particular mattress, you can check out the individual product page to find out its dimensions.
The weight of a king size mattress also varies. Mattress weight depends on several factors, including the materials it is made from.
King size mattresses usually weigh somewhere between 130 and 180 pounds (or from 59kg-82kg).
Knowing how much your mattress weighs can help you to choose a suitable bed frame. Bed frames will specify the maximum weight they can support, and the weight of the mattress will contribute to this total maximum weight.
Check the individual mattress product pages to learn how much each mattress weighs.

Different sleepers will ultimately want different things out of a mattress. But at Bensons for Beds, we’ve got options to suit every need and want. Here are some examples of the different king mattresses we have available:
King size orthopaedic mattresses: A king size orthopaedic mattress is ideal for anyone who suffers sleep disturbance due to aches and pains. Whether it’s because of back or neck pain, or just due to you preferring a firmer mattress to sleep on, an orthopaedic mattress in king size could be a good pick for you.
King size memory foam mattresses: If you love the conforming nature of memory foam, a king size memory foam mattress could be just what you need to get a great night’s sleep. Mattresses made from memory foam give sleepers a personalised feel while delivering excellent relief to key pressure points. King memory foam mattresses (or any size memory foam mattress) are also great at reducing motion transfer so could be a winner if you or your bed partner are regularly woken during the night by movement from your co-sleeper.
King size pocket spring mattresses: If you’re hot sleepers, you like to move around a lot in your sleep, or you’re looking for consistent support, a king size pocket sprung mattress may be ideal. These individually wrapped springs promote air flow in the mattress which helps stop heat building up. King pocket spring mattresses are also extremely responsive while minimising the risk of motion transfer too. When it comes to a great all-rounder, pocket sprung mattresses are usually a good shout.
King size hybrid mattresses: A king size hybrid mattress gives sleepers the best of both worlds. Hybrid mattresses combine springs and foam to help provide sleepers with consistent support, cushioning for key pressure points, and a cool and comfortable sleep.
King size zip and link mattresses: Partners don’t always agree when it comes to sleep. If this sounds familiar, a zip link king mattress could help you both benefit for a great night’s sleep. Zip and link mattresses are essentially two mattresses that you can be zipped together to create one king size mattress that two people can sleep on comfortably. This means that two individuals can choose different comfort ratings (or firmness ratings) within the same mattress wherever necessary.
King size latex mattresses: If you’re prone to overheating when you’re in bed, or you suffer from allergies, a king size latex mattress might be what you need. Find out why in our informative Latex Mattress Buying Guide.
King coil mattresses: Opposed to pocket sprung mattresses, king size open coil mattresses are packed with hundreds of individual coils that aren’t individually wrapped. These mattresses are usually the most budget-friendly option and the benefits of choosing one include enhanced air flow and responsive support. Plus, open coil mattresses are usually lightweight too.
King size rolled up mattresses: A roll up king size mattress (or a king size bed in a box, if you prefer) is a great pick for anyone living in apartments, flats, or multi-storey buildings. Basically, anywhere where navigating from the front door of the building to the front door of your home is difficult to do, a rolled mattress can save you a headache. This type of mattress is delivered rolled up for ultimate manoeuvrability.
And that’s not all. We also have king size mattresses in our eco-friendly collection, king size mattresses under £500, and award-winning king size mattresses too.
The price of a good king size mattress can vary, depending on what kind of mattress you are looking for. Here at Bensons for Beds, we have a range of high-quality king-size mattresses available to suit every budget.
You don’t need to spend a fortune to enjoy a restful night’s sleep on a new mattress in king size.
