The size of your mattress can make a world of difference to your sleep and your lifestyle. The last thing anyone needs after a long, tiring day is having to fight with your bed ‒ or your partner ‒ to make enough room for that much-needed rest. So how do you know which size best suits your needs? We’ve put together a simple bed size guide in cm, and recommendations, that will help you make the right choice.

Bear in mind that, as a general rule, the length of your bed should surpass your height by at least 10 cm when lying down ‒ giving your head and feet enough room for comfort, movement and undisturbed rest.
