What Size Is a King Single Mattress?

A king single mattress is a popular choice for those needing more space than a standard single but less than a double. Measuring approximately 106 centimetres in width and 203 centimetres in length, the king single offers extra room, making it ideal for growing children, teenagers, or adults who prefer a more spacious single sleeping area. 

This size is notably longer than a regular single mattress, providing ample legroom, which is particularly beneficial for taller individuals. The dimensions of a king single make it a versatile option for smaller bedrooms or multi-use spaces, as it balances the need for comfort with efficient use of space.

How Thick Are King Single Mattresses?

King single mattresses, like other mattress types, come in a variety of thicknesses to cater to different preferences and needs. Generally, their thickness ranges from about 20 centimetres (8 inches) to around 35 centimetres (14 inches). The mattress construction and materials influence the thickness. For instance, a basic innerspring mattress might be on the thinner end of the spectrum. In contrast, more luxurious memory foam, latex, or hybrid mattresses can be thicker due to additional comfort and support layers.

The thickness of a mattress can affect its feel and support level. Thicker mattresses often provide more cushioning and are better for those who prefer a plush sleeping surface or require extra support for joint or back issues. 

What Types of King Single Mattresses Does Factory Buys Sell?

At Factory Buys, we strive to provide all Australians with the perfect sleeping experience. We know that no two people are the same, which is why we offer a wide range of king single bed mattresses to cater to each person’s needs. The types of mattresses we sell include:



If you’re unsure which mattress style suits your needs, we suggest consulting with a sleep expert before purchasing.

How Many People Fit on a King Single Size Mattress?

A king single mattress, measuring around 106 centimetres in width and 203 centimetres in length, is ideally suited for one person. This size provides more room compared to a standard single mattress, offering extra space for an individual to sleep comfortably. The added width and length make it a popular choice for teenagers, tall individuals, or anyone who prefers more space than a traditional single bed provides. 

While it's spacious for one person, accommodating two people on a king single mattress is not recommended, as it would be quite cramped and likely uncomfortable. The king single is designed to blend the benefits of space efficiency with the comfort of an additional personal sleeping area, making it an excellent choice for solo sleepers who value extra room.

How Much Does a King Single Mattress Cost?

The answer to this question greatly depends on the manufacturer and website from whom you purchase it, as it varies from brand to brand. At Factory Buys, however, we can assure you that we only offer the greatest deals. You can find a low-cost king single mattress of high quality! It’s a win-win situation.
