What is the best king single mattress?

This is always going to be a matter of opinion, which is why we ensure that we stock an extensive range of king single mattresses, providing you with the choice you need. The best king single bed mattress for you will always be the one that feels the most comfortable.

Do 2 king single mattresses make a king?

No, all sizes of mattresses have specific measurements. A king single bed mattress is the same length as a king size mattress, at 2,030mm. However, a king single size mattress is 1,055mm wide, while a king mattress has a width of 1,835mm. If you put two king single mattresses together, you would create a huge width of 2,110mm, far wider than a standard king mattress. This might be a good solution if you require a very large sleeping area and have a generously sized bedroom! In most homes, however, this would be too big.

How do I choose a good king single mattress?

There are several factors you need to consider when choosing the right single king mattress for you. In addition to selecting a product from a respected manufacturer, you need to think about the feel of the mattress. Some sleepers like a firm mattress, as this provides you with a sturdier base, giving you more support while you sleep. Other sleepers might prefer a medium mattress, offering the perfect combination of strength and softness.

Those who want the ultimate in luxury can choose a plush mattress. This is the softest option, giving warmth and a cosy feel. We offer a full range of mattress options, enabling you to select the product which best suits your personal needs and preferences.
