Bed sizes are labelled differently in the United Kingdom. The United States queen is referred to as a king in the UK and it is two inches shorter.
The UK equivalent to the US king is referred to as a super king and is again two inches shorter compared to a king in the United States.
The UK king, which measures 150 by 200 centimetres is the ultimate choice for comfort for couples. It is what you need to eliminate tossing and turning when sleeping with a partner.
A UK king alleviates restless legs, improves blood flow, eases breathing, and allows a couple to sleep in proper positions without interfering with each other’s sleep.
But there are too many options on the market. This can be confusing because individual brands have emerged with unique marketing tactics that can mislead you.
We have done the assessment on your behalf, and the following are the products that we believe you and your partner are looking for.

King Size Mattress: Buying Guide
Space is very important when sleeping, which is usually inadequate when sleeping with a partner on a limited surface.
So, the simplest solution for couples in the UK is to buy a UK king mattress. But the size alone will do you no good. You have to consider the built-in features of the mattress.
What is the perfect sleep experience? How do you quantify comfort? The answers to these two questions depend entirely on the mattress design you choose.
These are the most popular beds in today’s UK market. Modern day foam beds are favoured by most people in the United Kingdom because of the advancements that have been made.
Unlike before, the contemporary types of memory foam have been improved in design and functionality.
Most people used to complain that traditional foams were hot and uncomfortable, but that is not the case anymore.
Newer types of memory foams have emerged, such as convoluted or egg crate foam and gel infused memory foam.
The main focus of most memory foam bed manufacturers is contouring support, moulding comfort, pressure relief and cooling.
In fact, the aforementioned factors are what should guide you in your search for a memory foam mattress.
You want a UK king memory foam bed that will not sink too deep, but just offer the ideal contouring to relieve pressure points.
You want a bed that has point elasticity. This will ensure you and your partner don’t toss and turn the whole night due to discomfort.
But most important you want a foam mattress that features exceptional cooling properties, which starts with the topside cover all the way to the core of the bed.
Latex beds are exceptional when you and your partner are seeking for buoyant support and adaptability.
Latex is naturally elastic and resilient, which makes these beds excellent for adjustable bases. The resilience of latex makes it highly durable and long lasting.
A latex mattress contours to every part of your body, providing exceptional support. This ensures you experience no pressure points.
The natural elasticity of latex also helps to eliminate motion transfer. A turning and tossing partner won’t interfere with your sleep.
The ultimate choice for a UK king mattress is the hybrid design. This offers you the benefits of both worlds. Hybrid UK king beds are favoured for their spring feel.
A hybrid bed usually contains individually wrapped spring coils and layers of memory foam and/or latex. The comfort of this design depends mostly on the comfort layers.
The individually encased springs are known to offer targeted support and promote proper spinal alignment. These combinations of features are invaluable for back pain sufferers.
The thickness and Edge Support
A concern that may not be immediately obvious when choosing a quality UK king size mattress is usually the thickness.
When various thicknesses of a mattress of the same density are compressed by the same load, the indentation of sleep surface increases with the mattress thickness.
This implies that a thicker mattress will contour with your body curves perfectly, supporting your vertebral column effectively while eliminating pressure points.
Normally, stress transfers in a thick bed easily compared to a thin bed. Therefore, a thick bed has a superior response to weight, which guarantees longer service life.
One of the highlights of any good king size mattress is an edge to edge support without which you have a limited sleeping surface.
A quality king mattress should not only reduce motion transfer but should also be able to provide targeted support at the edge.
Good edge support also makes it easier for you and your partner to get into and out of bed easily without sinking too deep at the edge.
You don’t have to squeeze in a UK double, you can improve your sleeping experience by upgrading to a UK king mattress.
What is most important is the design of the bed. The most popular UK king mattress designs are hybrid (consisting of pocket springs) and memory foam. You can still consider latex/air beds.
For maximum support, contouring, pressure relief, comfort and durability. We advise you to consider a thick mattress with a superior indentation load deflection.
You should also go for brands with a reputation of producing high performing king mattresses, such as Evergreen Web, Simpur, Emma and Simba.
